Adidas' shoe code is large or small

If the size of Adidas shoes you buy is wrong, this is normal, because different brands have their own shoes size tables, and the shoes are different, and they will have different sense of foot.

For example, Adidas's football shoes and tennis shoes may be small, because these shoe types must be pasted, running shoes and Outdoor shoes will be a bit larger, so that the comfort will be better.

If you want to buy the right shoe type, it is best to go to the store to try on, so as to buy the most suitable shoes.

When you compare the size of the size, it is best to compare the size of Asia. The size of Asia is very standardized, so that it is easier to buy the appropriate number.

The size of Adidas shoes can be queried by the shoe label and shoe box stickers. Adidas shoes include US, UK, EUR, and CM units. Domestic reference EUR size is generally referred to.

1. What is the structure of the water drop wheel

The original intention of the water drop wheel is used for long -range and its bait, which uses the principle of horizontal winding, and can rotate the wire shaft.The line shaft is used to activate the line through the rocker to activate the line through the brakes.The structure of the water drop wheel is as follows:

1. Put the line switch(Spool Release Button): Press it to qualify, shake the handle and reset.

2. Line cup(SPOOL): Line cups are not only important for the storage line, but also for the smoothness of the throwing distance.Generally, the line cup is made of aluminum alloy. The high -end line cup is made of aluminum, and the conventional wire cup is made of die casting aluminum.

3. brake(Brake): Adjust the initial speed of the wire cup and the initial flight speed of the line set, control the deceleration rate of the line cup.

4, wheel seat(Reel Foot): Fixed part of the fishing rod.

5. Ceramic outlet(LINE Guide): Move with the line shaft to ensure that the upper and down shafts are guided without a large angle.

6. Rocked arms grip(Reel Handle): There are two types of left rocker and right rocker. The water Drop wheels cannot be swapped like a spinning wheel, so the most suitable rocker arm needs to be determined.Using the right rocker with the right hand, the fishing wheel is on your left side, shake the handle with the right hand.

7. Star -type unloading force wrench(DRAG): Adjust the outline of the circuit.Generally, the regulation of the unloading force is 80 %, and it is urgently adjusted according to the situation when it needs to be adjusted.

8. Filter the knob(Spool Tensioner KNOB): The adjustment of the mechanical brake power, the tighter the tighter cup, the slower, and the faster.

9. The fuselage framework(Body Frame): It is made of aluminum alloy or carbon fiber, and the carbon fiber framework is light. It is recommended to find an integrated framework made of the same material. High -end fishing ships are usually made of integrated aluminum alloy framework.

Second, the disassembly and assembly tutorial of the water drop wheel

1. Preparation tools.Prepare the tools, such as screwdriver, wrench, tweezers, etc.

2. Disassemble external components.Use a screwdriver to unscrew the fixed screws outside the water drop wheel, remove the side cap and the wire cup, and pay attention to keep the screwdriver vertically vertically to avoid damaging the screws. For tight screws, do not use brute force.The strength was loose until the screw was loose.

3. Disassemble internal components.Press the end of the dealer or fingers to hold one end of the deck, and pinch the deck with the other end with a pointed tweezer. When removing the gear shaft, you need to pay attention to the pads on the axis, large metal teeth, friction pieces, rebound tooth sheets and other parts.It may need to be disassembled with a specific Tool, such as the top poles of the shaft, and each component is placed in order when disassembling to avoid errors when loading.

4. clean and repair.During the disassembly process, you can clean and repair the interior of the drop wheel, such as replacing the sealing ring or repairing damaged components.

5. Re -assemble.After the disassembly is completed, put all components in order. Do not miss any small components and small cushions. During the return process, pay special attention to the direction and order.

6. Check and test.After completing the assembly, check whether the drops of water drops work normally to ensure that there is no leakage or other problems.

What is the fishing snowmanship

Snowflake, it is a white sheet made from dehydration, dryness, and expansion.Its texture is lighter, and the proportion of water before absorbing is only about 2/3 of the water.After water absorption, it can appear suspended in the water.

We use cooler powder when we usually make bait when fishing, mainly because of two aspects: one is that it can effectively produce atomization; two is to change the proportion of the bait itself.

When adding cedar powder, you must control its amount. If too much, the bait will become too loose, the atomization is too fast, and the remaining hook is not enough.If excessive atomization, it will attract small miscellaneous fish to affect normal fishing.The appropriate addition of snow pollen can make the bait scatter in the fishing layer we booked, and achieve a good fish -liquidation effect. For example, mixing the snowflore and the large granular granules during the bottom fishing.In the bait, the bait is scattered at the bottom very well, which can effectively lure fish and leave fish.

When floating fishing, we need to increase the ratio of cedar powder in an appropriate amount, which can not only make the bait lighter, but also conducive to fishing, but also make the bait at the middle and upper layer.The ground attracts the nest.

The role of snowflake powder

When we are fishing, whether it is rubbing the bait and fishing bottom, or pulling the bait to fishing the bottom, especially when we pull bait fishing, we can't do without snow pollen.Everyone knows that the snowflore powder is strong. When mixing bait, it plays a sticky effect. When the pole is thrown, the bait does not disperse. After entering the water, the bait begins to be atomized and scattered. A little bait can be left on the fishing hook., And it is convenient for fish to eat.

Snowflames use tips

The amount of snowflake should be dependent on the fishing situation at that time.The depth of water, the height of the water temperature, the size of the fish, the fast and slow hook, the bait, the bait or the rubbing or the rubbing, the bottom fishing or floating fishing, etc. to comprehensively determine it.Generally, it is: deep water, large fish, low water temperature, and slow food hooks. When fishing for the bottom, it should be added appropriately, and the contrary will be less.The specific amount of additional amount is also asked to ponder and summarize more in practice.

How far can the Telescope look at

1. The distance between the Telescope is related to human vision.For example, the letter on the vision table: When "E" is 5 meters away, people with good vision can see the bottom line. People with myopia may only see the previous lines of "E".If you put the vision to 50 meters away, with a 10 -fold Telescope, it is equivalent to 10 times (the same as 5 meters away).People with good vision can still see the bottom line. People with myopia still can only see the big "E" in the front, and the bottom is still unclear.People with myopia will say that this Telescope can't see 50 meters, and even the bottom letters cannot be seen clearly, and people with good vision will say that this Telescope is very good. Even the bottom of the vision table at the bottom of 50 meters is still clearly seen.EssenceCan you say that this Telescope can only watch 50 meters?

2. The distance between the Telescope is related to the size of the object.For example: there is an ant at 1000 meters. You use 10 times the Telescope, which is equivalent to looking at the ants near 100 meters. You must not see it.Can you say that this Telescope can't see 1,000 meters?If you are a personal at 1000 meters, you use a 10 -fold Telescope, which is equivalent to pulling people closer to 100 meters. You must see it clearly.With a Telescope, you can clearly see the mountains of the moon at 380,000 kilometers, but you can't see the earth satellite that is much more than us. This is the truth.

3. The distance of the Telescope is related to the quality of the air.For example, using the same Telescope, the same person observes a billboard at 1,000 meters.After the rain, in the sunny weather, you can clearly see the small words on the billboard.In the case of no sun and air in the cloudy days, there are cars and dust in the air, it may not be clear.Furthermore, if there is a fog, that is, there are a lot of suspended particles in the air, and the visibility is reduced. You may not even see 5 meters.This is why the heavy fog weather blocks the highway.

4. The distance of the Telescope is related to the quality of the Telescope itself.Two parameters of the two Telescope (multiple, diameter, field of view, pupil distance, pupil diameter), Telescope with exactly the same size, the price may be several times or even more, there is nothing weird.The price and multiple of the Telescope have little to do, and the military Telescope has almost no more than 10 times.The lens, prism, coating, and structural parts of the Telescope determine the quality of the Telescope.A good Telescope light transmission can reach more than 90%, and the poor Telescope is only 50%-60%. The poor Telescope watching the sky is obviously dark.

You should understand why the Telescope does not see this data?As long as there are unlimited objects, the Telescope can see infinite far.With hundreds of light -year planets, we can see it without a Telescope, and we can also see with a Telescope.The moon is far away from us (380,000 kilometers), and we can see it with a Telescope.But no matter how good you are using a good Telescope or a close distance, you can't see it. Why?Because they are too small!

Basic principle of Telescope

The Telescope is an optical instrument used to observe long -distance objects. It can amplify a small horns with a small corner at a certain magnification, so that it has a large corner in the like space, so that the naked eye cannot be seen or could not see or can be seen or could not see it.The distinguished object becomes clear and distinguished.Therefore, Telescope is an indispensable Tool in astronomical and ground observations.It is an optical system that keeps the incident parallel light beam through objectives and eyepiece.It is generally divided into three types.

1. Introduction and principle of refraction Telescope

The refraction Telescope is a Telescope with a lens camera mirror.It is divided into two types: Galileo Telescope with melter mirror as a eyepiece mirror.The birch mirror is called the Capeler Telescope.

Galileo Telescope is a mirror that is a convex lens and a eyepiece is a concave mirror Telescope.The real image of the light through the refraction of the objective mirror is on the focus of the eyepiece (behind the purpose of the person). This is like a virtual image of the pair mirror, so it is refracted into a magnifying positive image.The magnitude of the Galileo Telescope is equal to the ratio of the focal length of the material mirror to the focal length of the eyed mirror.Its advantage is that the lens barrel can be short and can be positive, but its vision is relatively small.Two Gali Lue Telescopes with a low magnification of the magnification are tied together. In the middle, a bolts can be used to adjust their clear degrees at the same time, called "Drama mirror".Because it is easy to carry, it is often used to watch performances.The Telescope invented by Galileo has an important position in the history of human understanding of nature.Its advantage is that the structure is simple and can be directly in the right image.

The Capeler Telescope is composed of two convex lenses.Because there is a real image between the two, which can be convenient to install the branch board and excellent performance, professional -grade Telescopes such as military Telescopes and small astronomical Telescope are currently adopted.But this constitutional imaging is inverted, so it is necessary to add a positive system in the middle.

There are two types of systems: the prism is like the system and the lens are like the system.Our common front -wide and narrow typical binocular Telescope uses the two right -angle prisms.The advantage of this system is that the optical shaft is folded twice at the same time as positively, which greatly reduces the volume and weight of the Telescope.The lens is like a set of complex lenses as the system.

Due to the color difference between the mirror mirror and the ball difference, the modern refraction Telescope often uses two or more lens group crop mirrors.Among them, dual lens mirrors should be most commonly used.It is composed of convex lens made of a crown glass that is close to each other and a concave lens made of a piece of fire stone glass. It can completely eliminate the color difference between the two specific wavelengths, and the color difference of the remaining wavelength can also be weakened accordingly, as shown in Figure 2 in Figure 2Show.

When meeting certain design conditions, the gap and comets can be eliminated.Due to the effects of the remaining color difference and other aberrations, the relative caliber of dual lens mirrors is small, generally 1/15-1/20, rarely greater than 1/7, and the field of view is not large.Dual lens mirrors with a diameter of less than 8 cm can combine two lens glory together, called double glue compound mirrors, and there is a dual -separated mirror with a certain gap without glue.

In order to increase the relative caliber and field, multiple lens mirror groups can be used.For the Galileo Telescope, the structure is very simple and the light can lose less.The lens barrel is short and light.And it is positive, but the multiples are narrow, which is generally used for drama mirrors and toy Telescopes.For the Campler Telescope, you need to add a prism or a lens group to the image behind the object mirror to make the eyes observe the positive image.The general refraction Telescope uses the Capeler structure.

Because the imaging quality of the refraction Telescope is better than the reflected Telescope, the field of view is large, it is convenient to use, and it is easy to maintain. Small and medium -sized astronomical Telescopes and many special equipment are mostly refracted systems, but large refractive Telescopes are much more difficult to make than reflecting Telescopes because the smelting is large, because the smelting is large.The high -quality lens of the caliber is very difficult, and there is a problem with the absorption of light in the glass, so the large -diameter Telescope uses reflex.

2. Introduction and principle of reflection Telescope

The reflector Telescope is a Telescope with a concave reflector.It can be divided into several types such as Newton Telescope Kedar Telescope.

The principle of Newton's Telescope is to reflect the light on a focus using a curved mirror.This design method is several times higher than the magnification of the object to enlarge the object.It uses a parabolic mirror as the main mirror, enters the bottom of the lens barrel, and then folds back to the second reflector (diagonal reflex mirror of the plane), and once again changes the direction into the eye mirror focus plane.In order to observe, the eyepiece is placed near the side of the top of the Telescope lens barrel, as shown in Figure 3.Newton's reflection Telescope replaces the expensive and bulky lens collection and focusing on the light, thereby reducing the cost.

Newton's reflected Telescope system has a focal length of up to 1000mm and is still relatively compact and portable.Because the main mirror is exposed to air and dust, the Newton's reflectors Telescope requires more maintenance and maintenance.However, this small disadvantage does not hinder the popularization of this type of Telescope. For those users who want a price economy, they can still solve the weak observation and distant targets, Newton's reflecting Telescope is an ideal choice.Due to the principle of optical systems, the imaging of Newton's Telescope is an inverted image, which does not affect astronomical observations. Therefore, Newton's reflection Telescope is the best choice for astronomy.Through an additional lens such as the mirror, the image can be corrected, but the image quality will be reduced.

The Carse Green Telescope has a main mirror of the parabolic mirror, and the dual -curved secondary mirror reflects the light and passes through the hole in the center of the main mirror.In the lens of the small Telescope and camera, the secondary mirror is usually installed on the optical platform on the transparent optical glass board with a closed Telescope lens barrel.Such a device can eliminate the "star" scattering effect caused by the spider -type supporting frame.Although the closed lens cylinder will cause losses in the amount of light, the lens barrel can be kept clean and the main mirror can be protected.

It uses some characteristics of bilateral and parabolic reflection. The concave parabolic reflection mirror can converge all light in the light shaft into a single point -focus.The bilateral reflector on the convex surface has two focal points, which will reflect all light through one of the focus to the other focus.The lens of this type of Telescope will be placed in the design of sharing a focus in design so that the light can be used in another focus of the bilateral mirror for observation. Usually external eyepiece will also be at this point.The main mirror of the parabolic surface will enter the parallel light reflection of the Telescope and converge on the focus. This point is also a focus of the bilateral mirror.Then the dual -curved mirror reflects these light to another focus to observe the image there.

The main advantage of reflecting Telescope is that there is no color difference. When the object mirror is used, the ball difference can be eliminated.However, in order to reduce the effects of other aberrations, the field of view can be smaller.The materials that manufacture reflectors only require small expansion coefficients, small stress and easy grinding.The grinding reflectors are generally plated with an aluminum film on the surface, and the reflectivity of the aluminum film in the range of 2000-9000 Elaboratory is greater than 80%. Therefore, in addition to the optical band, the reflected Telescope is also suitable for the near-infrared and near-ultraviolet wave bands.research.The relative caliber of the reflective Telescope can be made large. The relative caliber of the main focus reflecting Telescope is about 1/5-1/2.5, or even more.There are only one surface of the main mirror that requires processing, which greatly reduces the difficulty of cost and manufacturing. Therefore, the current optical Telescope with a caliber greater than 1.34 meters is all reflecting Telescopes.A large -caliber reflecting Telescope can obtain the focus system (or Newton system), Kaserglin system, and folding system by changing different sub -mirrors.In this way, a Telescope can get several different relative caliber and field.Reflecting Telescope is mainly used for celestial physics.

3. Introduction and principle of reflecting Telescope

This kind of Telescope is based on the spherical reflex mirror, and then adds a refractive element for correctional imaging, which can avoid difficulty in large informal processing and get good quality quality.The more famous is Schmid Telescope, as shown in Figure 5.It places a Schmidt formal plate at the center of the ball reflector.It is one surface of the plane, and the other side is a mild deformation of the non -spherical, which makes the center part of the beam slightly converge, and the peripheral part is slightly divergent, just to correct the ball difference and comet difference.

The optical system of the Mark Subetov Telescope is composed of a concave spherical reflex mirror and a lens that corrected the ball difference in front, as shown in Figure 6.Correction of the lens is the sphere. The curvature radius of the two surfaces is not much different, but it has considerable curvature and thickness.Therefore, this system is sometimes called a moon mirror system.Properly select the curvature radius and thickness of the two sides of the lens, which can make the bending lens generate enough to compensate for the ball difference between the concave pads mirror, and at the same time meet the color elimination conditions.In the entire system, the distance between the bending moon lens and the spherical mirror can be corrected.The statue of the Macsolov long mirror optical system is very small, but the venue is relatively large, so it must use curved negatives that match the focus surface.The central part of the second side of the bending moon lens can be grinded into a spherical side with a longer curvature radius (it can also be a lens with a glue combined, which constitutes the Mark Subetov Kasselin system with relative caliber.Part of the central mirror part of the central mirror forms a Masukov-Carseglin system.

In addition to Schmidt Telescope and Mark Subov Telescope, there are two derivatives of these two Telescopes, such as Super Schmidt Telescope, Beck -Nuen camera, etc.In the refractive Telescope, the reflex mirror is used, and the refractive mirror is used for correctional image difference.It is characterized by a large caliber (or even greater than 1), strong light power, broad vision, and excellent quality.Suitable for celestial photography and observation of celebrities, comets, meteors and other celestial bodies.If a small eyes look at the reflected Katgreen system, the lens barrel can be very short.

What are the car emergency Tool packages

1. flashlight

3 AAA batteries can be used, and the battery needs to be matched separately.

2. Emergency trailer rope

The trailer is suitable for trailers for ordinary cars. The most heavier of the trailer must not exceed 3 tons; the rope of the bright orange rope is very eye -catching, and the vehicle can be reminded at night.

The tips of trailers: driving on uneven roads, or starting rapidly, and accelerating too fast, etc., will cause the trailer rope to be overwhelmed and break.Be sure to keep a slow starting, keep the trailer rope straight, move forward as much as possible, stop or turn in advance, you need to warn in advance, and the rear car needs to keep the synchronous brake or steering at any time.

3. battery fire line (500A)

When the vehicle is unable to start, use it to start with the battery of another vehicle.The 2 -meter -long battery startup is a thickened wire, which is generally suitable for the use of gasoline engines with a gasoline engine or a diesel engine battery with a displacement of less than 2500cc.

The two cars cannot have any contact, and the electronic system of the two cars must have the same voltage.If the battery is frozen, please do not use this startup line.Before the connection, the engines, audio, and air conditioners of the two cars need to be turned off.The connection program is as follows:

(1) First of all, the red wire of the startup line is on the positive pole of the red battery of the "rescued car".

(2) Then the red wire of the other end is clawed on the positive electrode of the red battery of the "rescue car".

(3) Put the black wire on the black negative battery of the "rescued car".

(4) Then hold the black wire on the black negative battery of the "rescue car".

(5) Start the engine of "rescue car" first, and then start the "rescued car" engine.If you find that the rescue car is still unable to start, please check whether the metal contact part is poor.After completing the startup engine, the starting fire line is still needed to be removed in order, otherwise it may cause short circuit.

The dismantling wire program is as follows:

(1) First remove the "rescued car" black wire.

(2) Remove the black wire of the "rescue car".

(3) Then remove the red wire of the "rescue car".

(4) Finally, remove the red wire of the "rescued car".

4. Vehicle fuse (6 pieces)

The function of the fuse is to protect the circuit (line) and electric equipment. Occasionally, when the vehicle is used, it is found that the headlights are not on or the wiper is not available. In this case, we should first suspect that the fuse is damaged.Generally, the fuse of the headlights is 20A or 30A specifications. The insurance of the cigarette lighter is 10A or 15A, and the insurance specifications of the wiper are around 45A.Generally, the insurance box of the car is below the steering wheel. There is a logo next to each insurance in the insurance box, and there is a backup fuse in the insurance box.This product is equipped with 6 backup fuses, including 15A*2, 20A*2, 30A*2.

When replacing the fuse, you must be consistent with the original fuse specifications. You cannot arbitrarily increase the current level of the fuse, and you cannot use other conductives instead.If the fuse that is changed is burned again, it means that the circuit has a short -circuit failure, and the professionals should be asked to exclude the failure before installing the fuse. Do not use the addition of fuse specifications to deal with it, otherwise it is likely to cause a fire.

5. Emergency raincoat

Put on rainy days or fog to prevent clothes or heads from being damp.It can be used for insulation or parcels under harsh conditions.

6, reflective vest

On the highway or at night, seeking it to wear it when seeking rescue or car repair can play a role in warning forward vehicles and obtaining safety guarantees.In addition, cycling at night or walking on the street can also be worn to ensure the safety of warning.

Large size, there is a magic buckle on both sides, which is suitable for different figures.(Special reminder: Most of the domestic highways have no street lights, the sky is darker or the off -car operation needs to be worn on the car)

7. Cotton anti -sliding gloves

Driving is inevitable when it comes to self -repair when it is faulty, such as changing tires and checking engines. Wearing gloves not only prevent the hands from being stained or injured, but also non -slip, making the work more interested.The whole cotton yarn is woven, and the titer of the titer is non -slip particles, which provides a comfortable feel.

8. Tire replenishment Tool

Specifications: 1 set of features: Tire cold -toned strip products are the use of tire supplementation methods that use tires to roll up the vulcanization process to firmly paste the tires and tires.This method of tireing is fast, convenient, reliable, and safe, and has become a portable tire supplement product that owners generally choose.

9. Tire inflation machine (can be set with tire pressure, LCD display)

Digital LCD display can set tire pressure pump.

10. Triangle warning sign

I believe no netizens do not know the role of the triangle signs.It is a very important Tool. When a sudden incident occurs, it placed it behind the car to remind the rear vehicles to avoid timely and avoid the occurrence of secondary accidents.

11. Wire

Now the new cars are generally equipped with tire wrench with the car.When the tire fails, it can be replaced by itself in time.

12.fire extinguisher

The fire extinguisher is an important car Tool for fire extinguishers, but many car owners are not equipped with fire extinguishers for cars. When dangerous, they can help help.

If the fire extinguisher pointer is in the "re -installation" area, it means that the gas pressure in the tank is lower than the normal use pressure; if it is "overcoming", it means that the normal use pressure is high. Remember to change the fire extinguisher.

13. Safety Hammer

Everyone knows that in the past, the glass of cars was shaken, so rarely was equipped in the car, and usually only appeared on the bus.However, with the alternative mechanical lifting of the electronics elevation, there is a hidden safety hazard in the rainy day of wading driving, that is, the windows cannot be opened after the wading.

At present, there are two types of functional safety hammer and multi -functional safety hammer on the market.When the owner encounters an emergency, if the window is needed, the four corners of the window are smashed with a safe hammer, because the middle part of the tempered glass is the most firm.

14. Message board

If you need to move your car, please call , sorry for the trouble that causes you.With a card with your own contact information with you, you can not only give people a convenient convenience when blocking others, but if you stop, other vehicles accidentally stuck to your car, which is convenient for other car owners to contact you. This is also convenient for other car owners.It is also good for yourself.

15. Pure water

Water is not only important for people, but also very important to cars.Especially in the hot summer, preparing a few bottles of pure water in the trunk is particularly important.It is easy to dehydrate when going out in summer, and long -term carriage air conditioners will also accelerate the dryness of the Skin, so frequent hydration is needed.

In high -temperature summer, the water tank water consumption of the engine of some old vehicles will increase, and it will even be opened.Therefore, when the water level of the water tank is low, you need to add a special water tank water in time. If there are no conditions, you can also use drinking pure water instead. You cannot use mineral water and tap water, because they are easy to produce scale in the water tank pipelineEffect.In addition, car owners who often use wiper and water cleaning function should also often need to add wiper cleaner. There is no one. It also needs pure water to help. If you can add some detergent, the effect is better.In order to prevent the scoop blocking the cleaning agent, tap water or mineral water should not be added.

The above only lists some common car emergency packages, and others have ice shovels, hydraulic jacks, and so on.In addition, tools like spare tires cannot be placed in emergency packages due to excessive volume, but if the space on the car is sufficient, it is better to have a spare tire.
