[Key knife classification] What are the Outdoor keys for key knife classification?

Usually we classify the key knife according to the size, such as 58mm, 91mm, 111mm.However, according to the characteristics of the inherent work on the key knife, you will find a very interesting method:

What are the key knife classification

1. Modification type: Representative -model (scissors and cut nails, nails repair nails, toothpicks to remove teeth, mule eyebrows)

2. kitchen type: Representative -Standard (knife cut fruit, bottle liter, kick -up can be opened, plug the plug and wood plug, toothpick picks water cubes)

3. home: Representative -climbers/concise (knife cut fruit, scissors and cut things, rose up the bottle canal wood plug, hook litter bag, etc.)

4. Urban suburban: Representative -Hunter/Farm Lord (on the basis of climbing, there is an extra wood saw or replaced the cross cone. With the meaning of Outdoor, it becomes a common type in the city and the suburbs)

5. Tool type: Representative -guerrilla/craftsman/famous craftsman/work champion (knife, clamp, cutting, wooden saw, steel saw, frustration, chisel, cone, cone, is the combination of tools)

6. Comprehensive: Representative -mini champion/Swiss champion (modification, kitchen, outskirts, urban dwellings, tools are all complete)

7. Professional type: Representative -fishing/Traveler/computer Master/Firefighter/Rescue Tool

8. Defense type: Representative -sentinel (single opening, lock, long enough, you can "go straight" single -knife)

9. Wild appearance: Representative -hunter (cutting, wooden sawing wood, sickle stabbing grass, drilling cone drilling)

10. Mixed type: Representative -Poor/German officer (there are many types of this category. On the basis of the field of wildness, there is a cross -word cone to be repaired.

precautions

Through the above classification, you can clearly know which style of Outdoor multifunctional saber you want.

Polarized Microscope principle

1. Single refraction and dual refractive

When the light passes through a certain substance, such as the nature of light and the pathway does not change due to the direction of illumination. This substance has "different sexual sex" in optics, also known as single refractive body, such as ordinary gases, liquids, and non -crystalline.Solid; if the light is through another material, the speed, refractive index, absorption and polarization, amplitude of the light are different due to the illumination direction.Such as crystal, fiber, etc.

2. The polarization phenomenon of light

Based on the characteristics of vibration, light waves can be divided into natural light and polarizing light.The vibration of natural light is characterized by many vibration surfaces on the vertical light wave conduction shaft, and the amplitude of vibration on each plane is the same; natural light is reflected, refracted, double refraction and absorption, etc.Given light waves are called "polarizing" or "polarized light".

3. The generation of polarization and its role

The most important part of polarizing Microscope is polarizing device -polarizer and polarizer.In the past, both of which were composed of Nicola prisms. It was made from natural squarestones, but due to the large limitation of the crystal volume, it is difficult to obtain a large area of polarization. Polarized Microscope uses a artificial polarizer to useReplace the Nicor Slutter.The artificial polarizing mirror is made of sulfate, also known as the crystal of HERAPathite, which is green olive.When ordinary light passes through it, it can obtain a straight line polarizing light that is only vibrated on the line.

Polarized Microscope has two polarized mirrors, one is called "up mirror" between the light source and the object of the object;Attachment is for operation, which has the scales on the rotation angle.When the light from the light source through two polarized mirrors, if the vibration direction of the mirror is parallel to each other, that is, when the "parallel inspection bias" is in the case, the field is the brightest.Conversely, if the two are vertically each other, that is, when they are in the "bias of the Zhengjiao school", the field of view is completely dark. If the two are tilted, the field shows a medium degree of brightness.It can be seen that the straight line polarization formed by the mirror, if its vibration direction is parallel to the vibration direction of the mirror, it can be completely passed; if the partial slopes are oblique, only a part is passed; if it is vertical, it cannot pass.Therefore, when a polarized Microscope is used, in principle, the upper -mirror and mirror mirror should be carried out in a state of positive cross -check bias.

4. Double refractive body under the bias of the right inspection

In the case of orthogonal intercourse, the field of view is dark.The vibration direction of the polarized light formed does not change, and the vibration direction of the vibration of the mirror is still perpendicular to each other.If the inspection object has dual refraction or substances containing dual refraction characteristics, the vision field with dual refraction characteristics is brighter. This is because the straight -line polarization light shot from the upper mirror enters the double -folding body, and the vibration direction will generate the vibration direction.Different two kinds of linear polarization light. When these two Lights pass the mirror mirror, because another beam of light does not orthogonal with the direction of polarizing mirror polarization, you can see the bright mirror.elephant.When the light is dual -refractive, the two polarized light vibration directions are formed, which are different according to the type of object.

When the dual refractive body is orthogonal, when the rotating loading table, the elephant of the dual folding body changes four times in the rotation of 360 , which is darkened every 90 every 90 .The position of the darkening is the two vibration directions of the dual refractive body consistent with the vibration direction of the two polarizers. It is called the "light position" rotating 45 from the lighting position and the body becomes the brightest. This is "The diagonal position ", because when deviating 45 , when the polarizing light reaches the object, the light can be decomposed by the mirror that can be detected by the mirror, so it is bright.According to the above basic principles, the use of polarized micro -surgery may determine the same oriental (single refractive body) and the opposite sex (dual refractive) substances.

5. Interference color

In the case of biased positions, the dual refractive body is observed as a light source with a variety of different wavelengths. When rotating the carrier table, not only the brightest diagonal position appears in the field of view, but also the color.The cause of color is mainly caused by interference colors (of course, the object itself may not be colorless and transparent).The distribution characteristics of the interference color determine the type and its thickness of the dual folding body. It is due to the dependence of the wavelength of different colors of light.The color of the mirror light is different.

Polarized Microscope use precautions

1. The laboratory should have three anti -prevention conditions: shockproof (far away from the source of the Earthquake), moisture -proof (using air conditioners, dryers), and dust (floor floor).Power: 220V -10%, 50Hz temperature: 0 degrees -40 degrees.

2. Be careful not to make the material mirror encounter the sample to avoid scratching the material mirror.

3. Do not switch the mirror when the center of the loading table is close to the center of the object mirror, so as not to scratch the material mirror.

4. Brightness adjustment should not be large and small, and do not light up, affect the service life of the Light bulb, and at the same time damage.

5. Switch all the functions, the movement should be light, and in place.

6. To minimize the brightness when shutting down.

7. Non -professional personnel should not adjust the lighting system (filament position light) to avoid affecting the quality of imaging.

8. Pay attention to high temperature when replacing the halogen Lights to avoid burns; be careful not to directly contact the vitreous of the halogen light with your hands.

9. When the shutdown is not used, adjust the material mirror to the minimum state through the focusing mechanism.

10. Don't use it if you don't use it, don't immediately cover the dust cover, and then cover it after cooling. Pay attention to the fire prevention.

11. The optical components that are not used often are placed in a dry dish.

12. Non -professional personnel should not try to wipe polarized Microscope mirrors and other optical components.The eyepiece can be dipped in a 1: 1 ratio (aquatic alcohol: ether) mixed liquid to dry after dried the sector cotton swab. Do not use other liquids to avoid damaging the mirror.

The difference between polarizing Microscope and ordinary Microscope

The main difference between polarizing Microscope and ordinary Microscope is equipped with two light components on the polarized Microscope, that is, polarizing mirrors and detect polarizers, so the structure of polarizing Microscope is more complicated than biological microscopes.Polarized Microscope is the purpose of analyzing and testing of crystal optical characteristics through the role of these two polarizers.

When testing the crystal, the polarized Microscope is placed on the carrier between the Polarized mirror and the Polarized mirror.The vibration surface of the two polarized mirrors should be vertical (orthogonal), then the field of view is the special nature of dark use of light polarization. It is applied to microscopic imagery technology and promotes the rapid development of crystal optics.The principles and methods of crystal optics are used to study minerals, rocks, slag, and refractory materials, which are convenient and accurate, so they are widely used in geological research and gold phase research.There are basically two ways to observe with polarized Microscope:

1. Use small pores to light up the light beam to light up the object. At this time, you can think that all the beams are perpendicular to the plane of the object, and you can directly observe the image of the object with a eyepiece.

2. Using a large -pores to concentrate on the light beam to illuminate the object. At this time, the pupils of the objective mirror will produce interference phenomenon that indicates the nature of the objects observed.Interfering images formed.

[kitchen storage shelf] How to buy kitchen storage racks, how to use the kitchen storage rack for storage

How to buy the kitchen storage rack

There are many types of kitchen storage racks on the market. How to choose a suitable size Kitchen rack is a headache for the housewife.In general, the selection of kitchen storage racks should be screened according to the actual situation of the family.For example, a bowl rack, the housewives can first consider whether the size of the kitchen space in the home chooses or desktop; secondly, the number of dishes in the home must be considered.For another example, the housewives should first consider the space near the stove and the number of seasoning bottles.Overall, the selection and installation of the kitchen racks mainly pay attention to the following aspects:

1. Convenient and applicability: When installing the shelves, be sure to install the entire layout of the kitchen and the needs of our daily life. Commonly used, the installation location we need to use it at hand must be used.In other words, water is the place where we can reach for enough. We can install or place the vacant part of the kitchen.

2. Save space: Because the kitchen is relatively small in our family, the installation of the shelf must save space and use the location of our kitchen space reasonably, such as on the wall of the kitchen, the back of the kitchen door back, the back of the kitchen doorWaiting for these places.

3. The classification is clear: We must put them in a reasonable position according to their different categories when setting up the category of the kitchen.The drain can be installed next to the dishwashing tank. The knife rack can be installed on the corner of the stove. The seasoning rack is installed where it is closer to us.

How to use the kitchen storage rack for storage

The kitchen needs to use various utensils and items, such as kitchenware, tableware, condiments, etc., there are many types and quantities, and it is essential. Putting them at hand not only looks very messy, but not convenient to find it next time. At this time, the kitchen storageThe rack played a great role.The housewives can put these supplies in an orderly manner in the Storage rack to create a clean kitchen environment.

The shape of the kitchen shelf is usually three types: board, Hanging, and desktop.

Considering that the kitchen space is limited, most people still choose to hang the kitchen racks on the wall with a hanging type.

But it is not true that the placement of each Kitchen rack should be used as the principle of housewives.The following are some suggestions:

1. Place the drain of the soup plate to choose the plate type and place it by the pool for use at any time;

2. The knife rack should arrange a corner for it to avoid hurting yourself when you are busy;

3. The seasoning rack should be placed in a place near the wok so that the seasoning is convenient when cooking

5. There are some highly fixed tables installed in the kitchen. After putting various tablets and other tableware, there will be a feeling of waste of a high space. Then it is a good choice to use a Hanging small Storage rack.Reasonable use of the remaining three -dimensional space can be used to place various types of bottles and cans used for cooking, which is neat and convenient.

6. If the height of the table is not fixed, it doesn't matter. Choose a small multi -layer Storage rack to solve it.This kind of Storage rack occupies small space. Multi -layer space can store more items. The non -fixed placement method can freely adjust the position, which is very practical.

Generally, people think that it is difficult to clean up the kitchen, but it is unexpectedly simple if the purpose of "cooking".Pay attention to the kitchen storage: First, the minimal movement access; 2. The various sizes and shapes must be cleaned up;Tiring.Want to cook well and keep the distance between 2-3 steps between the "Refrigerator-cooking table-Storage rack".Putting things only need to reach out or step across.

Pay attention to things outside the kitchen. What often use should be placed in places that are easy to take, and things that are heavy should be placed below.Evolties should be avoided.

How to adjust carp in different seasons

spring

The warming of the carp is very strong. It will migrate the living environment with the change of water temperature. In the southern spring, in general, the activity of carp is still small. At the suitable temperature in March and April, part of the temperature, part of the part of the temperature, part of the part of the temperature, part of the part of the temperature.The two -pound carp will swim to the shallow water area near the shore to find food, and a small number of adult fish will find food in small -scale activities in the deep water area of the wide water surface, and weaken as the temperature rises or decreases in the morning and evening temperatures.It is also important. Because in the early seasons, most adult fish have not yet set seeds to throw essence. The "big belly" group of fish belly has always risen to affect appetite. Therefore, this period is not the ideal season for carp fishing.In the northern and even northeast regions, the foraging of carp activities in spring is almost zero.

summer

summer is the most active season of carp, and the change of meteorological conditions will also disrupt the activities of carp.The fisherman can interpret the law of carp in two periods: the first phase is the early stage of the rainwater. After a large amount of new water in the reservoir area, the water quality is improved, the amount of solubility is increased, and the fish is active.Especially adult carp will take this opportunity to start breeding offspring.In the cool drizzle or in the sunny morning, people often see large carps chased by large carps on the shallow beach in the shallow beach in large water areas.From late May to mid -June (the rain is slightly advanced or delayed sooner or later).Once the seeds are ends, the adult carp enters the food period, and it is almost all over the weather for food, and there will be a group of young carp to go to the shallow water area for food and play.Finding food with a wide water area is just fishing with sea rods.The second phase is the high temperature stage. The temperature is high during the day. After the sun rises, the carp swims to the deep water area. Foraging in the cool downstream of deep water.To grasp this feature and use the method of fishing, it is the best strategy to deal with the big carp.

autumn

The climate in autumn is cool. Some carp will travel from the deep water to the shallow water in the shallow water. At this time, there will be carp bite hooks in the long -term fishing, near, and shallow fishing, and it is very positive for foraging in the morning and evening.

winter

In the winter in the south, as long as it is a sunny day before mid -December, there will be higher temperatures. For carp that eats more than 10c of water, in the first half of the winter, it is still the "good date of finding food in the first half of the winter."Beautiful scenery", at this time, the carp will find food in the water areas of 2 meters from 78:00 to 4 or 5 meters from the water areas from 78:00 in the morning. Therefore, fishermen in various places often have the good news of winter fishing.

The state of foraging in carp activities will change with the quality of the weather.In the second half of the winter, the temperature was getting lower and lower. Occasionally, the temperature of the weather picked up, but it was not enough to promote carp activities to find food, especially in the north, so this period was basically fishing.

fishing carp bait formula

Sweet potato

Sweet potato (also known as Sweet potato) has a large sugar content and large viscosity, especially the sweet and more sticky Sweet potato.First wash the sweet potatoes, steam and cool the high -pressure cooker, cut into thin slices with a knife, and then use a pen hat (cylindrical shape) to press the small round bait on the Sweet potato chips.The king "and" Jinfeng ") are mixed, so that the small Sweet potato grains are sticking to the powder -shaped finished bait.When using, hang Sweet potato grains on the hook, and the powder bait on the Sweet potato grains scattered in the water. These powder bait scattered in the water seduce fish.You can also mix sweet potatoes into Sweet potato puree and mix it in finished bait or cake powder and bran powder as bait.

Cake powder mixed bait

Crush the cauliflower cake (or Peanut cakes, bean cakes), mix it with water into wet material, steam it in the pot, and mix various finished carp bait (such as the "old ghost" carp bait) when it is cool, add(Bone powder or fish powder, the bait is fragrant and fishy, the effect of fishing carp is very obvious.

Sesame sauce bait

Use bean cakes (Peanut cakes, sesame cakes are also fine) (about 500 grams), then fry the aroma, and bran (50 grams) also fried fragrance.Flour (50 grams), 250 grams of humidifying sesame scum, add some water in the fishing ground after the fishing ground, mix the above raw materials for bait, and can also be used as bait fishing for bomb hooks.

Sihe ~ Polying bait

Use 30 % cake powder (the best sesame cake powder, if there is no sesame cake powder, other cake Flour can also be done), three % of the Wheat bran is frying the aroma with the fire, and the water powder is used before use, and a small amount of fish powder and a small amount of animal blood powder are used.(Two kinds of Flour are combined to be 30 %), stir well, and add some Flour before the bait to increase the viscosity.

Fishy bait

500 grams of rice Flour, 100 grams of Flour, 50 grams of cake powder, 50 grams of fish Flour, mix the above bait with warm water, pinch into steamed buns, steam it for 5 minutes, open it after cooling, mix a small amount of fish powder and sugar), Put it in the bag and cover it slightly.

rice bean honey bait
