1. The working principle of the Bicycle code watch

The principle of the bicycle sheet is that the sensor captures the information brought by the inductive magnet when the car ring rotates, transmits it to the gauge through the sensing line, and the host code table is calculated to calculate the speed, mileage and other information after this process.

Popularly speaking, there is a magnet -like thing on the front wheels. There is a sensor on the front fork. The wheels turn around, and the magnet passes through the sensor once.In the wheel parameters, the code watch has calculated the speed and the journey.To put it simply, the airflow formed during the cycling process to generate induction of the wind hole of the code watch, thereby measuring the speed.

2. What is the reason for the Bicycle code watch

The bicycle codes are not allowed

1. The code table generally has only two keys. The "SET key" in the back is the setting key.Hold down the "SET key" behind the code watch for more than 2 seconds, and enter the setting mode after the screen displays "Set Open".

2. The screen displays "SIZE 2155", where the wheel value is set.Press "Big Key", the screen display "Unit Kmh", that is, the display value is "km/h".

3. Press "Big Key", the screen shows "Dist 0", which is the total mileage.Press "Big Key", the screen displays "time 00:02", that is, time.

4. Press "Big Key", the screen display "Scan OFF", that is, the scroll display mode is turned off.

5. Then go back to the "Time" interface, press the "SET key", the numbers flickered, and set the numbers according to the "Big Key".

6. After the time is adjusted, press the "SET key" again, the screen display "Set OK", and the time settings are successful.

7. Press the "SET key" behind the code watch for more than 2 seconds. The screen displays "SET Close", exit the setting mode, and then press "Big Key" to switch to time and check the setting time.

The average speed of the bicycle codes is not allowed

The biggest reason for the inaccurate speed of the bicycle codes is the incorrect setting of the perimeter of the wheels. Generally, the newly -bought bicycle sheet wheels need to be set. You need to accurately measure the size of the car, and then the code watch parameters follow the car circle according to the car circle.Settings.

The highest speed of the Bicycle code watch is not allowed

There are many reasons for the highest speed of the Bicycle code watch, but the reason is basically the same, that is, the wheels of the wheels have vibrated when the magnets of the front wheels pass through the sensor (sanitary Tube) through the code watch, such as overwhelming over the wheel, such as overwriting too much.A pit, a sudden brake, etc., made the magnet shake near the sensor of the code watch, so that the code watch thought that in this shaking time, the front wheels had turned around, so that there would be a very high high.Speed and recorded, this is normal, don't care.

Astronomical Telescope eye mirror type Introduction of astronomical Telescope mirror structure diagram

1. Huachangs mirror (H)

The Dutch scientist Huachaus was designed in 1703. It is composed of two flat convex lenses. The front is a field mirror and the back is a mirror. Their convex surface is facing the end of the object mirror. The focal length of the field mirror is generally 2-3 times the mirror.It is half of their focal length.Huachangs mirror is about 25-40 degrees.In the past, the Huachangs mirror was the first choice of a small refraction mirror, but with the increase of the light power of the Telescope, the disadvantages of the obvious disadvantages of the field of view, low contrast, color difference, and ball differences. Therefore, this structure is generally generally generallyUse the eyepiece of the Microscope.

2. Romans Deng mirror (R)

The design was successful in 1783, and it was also two -sets and two groups of structures. It was composed of two flat convex lenses with the same focal length and the same focal length.The spacing is 2/3-3/4, which is the focal length of the two. The color difference is slightly large, and the field song is significantly reduced. The field of view is about 30-45 degrees. At present, it is rarely used.

3. Klena mirror (K, RKE)

It was developed on the basis of Ranzesden mirror. It appeared in 1849. The main improvement was to change the single -piece lighting mirror to the dual -glued color differential lens, which greatly improved the improvement of color difference and edge image.At 40-50 degrees, there is a comfortable pupil distance when it is low, so it is currently widely used in some low-dimensional Telescopes, but it is not well performed when it is high.In addition, the field mirror of the Kelna eye mirror is close to the focal plane, so that the dust on the field mirror is easy to images and affects observation, so pay special attention to cleaning.

A US company has further improved on the basis of Kylene mirror and developed RKE eyepiece. The edge image is better than the classic structure.

4. Abbey disorders (or) (or)

Designed by Abe, one of the founders of Germany's Zeiss Company in 1880, it is a structure of four pieces and two sets. Among them, the field mirror is a three -glue lens, and the mirror is a flat -convex lens.Like and the field of the field to the degree of difficulty, it also has a flat field of viewing and sufficient pupils at a flat field of 40-50 degrees. It has a good performance in each magnification and has been widely adopted.

5. Ailifer wide -angle mirror (ER)

The successful development in 1917 was designed for military Telescopes that needed a large field of view. It was the originator of all wide-angle mirrors. The structure was 5 pieces and three groups, and the field of view was as high as 60-75 degrees.It is very suitable for observing deep space celestial bodies. Because the edges are scattered, it is not suitable for high -power design. Its performance in low times is very good.

6. Prove mirror (PL)

Also known as symmetrical mirror.It is composed of the two sets of two sets of dual -gluing color differential lenses. Its parameter performance is equivalent to OL eyepiece, but it has a greater pupil distance and field of view. The cost is lower, and it is suitable for all the magnitudeThe eyepiece has been assigned a variety of improved types.

7. Nagler's eyepiece mirror

A high -end eyepiece designed by Americans in 1979 has an amazing field of 82 degrees, high -quality edges like quality and comfortable pupils, as well as complex structures and high prices, and weight of more than one kilogram.

1. What are the conditions for opening a Fishing gear shop?

Nowadays, people's pursuit of life taste is getting higher and higher. Usually, fishing and leisure entertainment is also common. Especially some office workers and middle -aged and elderly people can fish for stress or self -cultivation.Seeing this market demand, many people also want to open a store to start a business, and it is naturally easy to open a store to meet everyone's needs. So what are the conditions for opening a Fishing gear shop?

Opening a store requires legitimate business qualifications. At this time, all documents must be fully prepared, including nuclear names, applying for business licenses, engraving rules, and tax registration instructions.In addition, you must also go to the bank to open an account and open it, and you must go to the taxation to report it. At this time, you will often use a copy of your ID card, a lease contract, and an application form. These are fully prepared.

2. Open the Fishing gear shop to join or buy it by yourself

1. Opening a store is the name of the franchise store. The headquarters will be distributed to you. You do nt need to go to the goods by yourself. You only need to pay a certain fee. You can pay for the decoration.It's right.Relatively easier, because the business philosophy is based on the headquarters.

2. It is more complicated to open the store by yourself. You need to go to the goods to make up. If you have a quality problem, you can find it to find the shipper. If you are a franchise store, you can find the headquarters to solve it. What is it?It s all done by yourself. Maybe you feel good as your boss, but there are a lot of troubles, and you need to do it yourself.

Both methods have their own advantages and disadvantages. What should I do if I need to connect with the actual situation and follow my own heart.

1. Is the quality of Anta's down jackets good?

The quality of Anta's down jacket is relatively good. The specific reasons are as follows:

1. Anta uses hot technology to give products better heating up and long -lasting locking attributes, bringing the warmest dressing experience

2. The "seamless pipe lock technology" used in short down jackets and medium -length down jackets use seamless processes in the main part, effectively improving the "Running down" problem.

3. The design of Anta down jackets has a sense of fashion and functionality. It is a good choice for Outdoor travel or urban tourism.

4. Anta down jacket adds TEFLON fabric protection auxiliary to the fabric, giving the "three -proof" attributes of oil -proof, water -proof, and moisturizing on the surface of the fabric, which can not only cope with the general light rain and small snow weather, but also help daily care.

2. How to choose Anta down jacket

1. See the material of Anta down jacket filling material

Everyone knows that the filling of down jackets generally has two types of "goose down" and "duck down". The former has many advantages such as strong warmth, more fluffy, elasticity, and small odor.Many.If you follow the color segmentation, you can be divided into "white goose down", "gray goose down", "white duck down" and "gray duck down".From a price point of view, white velvet is often more expensive than gray velvet.First, the fibrous tissue of white velvet is relatively fine, soft, long, and fluffy, and more warm; second, white velvet is wider, and gray velvet can only be used as filled materials for dark fabrics.In real life, we don't have to admire goose down, ordinary duck down is absolutely enough. The difference in warmth is actually very small, but the duck down smells a bit smell.

2. Look at the containing down content of Anta down jacket

The down jacket is usually filled with "fluff (also called velvet)", plus a certain proportion of feathers."Velvete content" refers to the ratio of "feathers" and "fluff".70%and 80%are currently the mainstream of the velvet content in the down jacket market (the national standards of down jackets in our country stipulate that the "velvet content of down jackets must not be less than 50%) and can meet the cold protection needs of most people, 90%contains containingVelvet (also known as 90 velvet) is the highest specification.

3. Look at Anta down jacket and charge

The volume contains percentage, and the "charging voltage-fill weight" refers to the weight gram of the filling.In other words, the higher the amount of down the down jacket in Anta, the longer the down jacket is fluffy and not flat. The longer the warmth, the better the warmth.Anta down jacket products & gt; & gt;

1. What is the difference between high carbon fishing rod and carbon fishing rod

1. Carbon fishing rod: Carbon Fish rod is called carbon fiber fishing rod. The so -called carbon fiber refers to carbonized fiber made of polypropylene fiber or asphalt and is made of high -temperature carbonized.It has the advantages of good toughness and light weight.

2124t30t36t40t46T, 60T, etc. The Fishing rods made of carbon cloth within 30t belong to ordinary carbon Fishing rods, and the Fishing rods made of carbon cloth more than 30t are high carbon Fishing rods.

In summary, the main materials of high carbon fish rods and carbon fish rods are carbon cloth. There are 24T, 30T, 36T, 40T, 46T, 60T, etc.30The Fishing rods made of carbon cloth within T belong to ordinary carbon Fishing rods, and30The Fishing rods made of carbon cloth above T are high -carbon Fishing rods.

Second, the low -carbon fishing rod during wild fishing is better or high carbon fishing rod

1. The advantages and disadvantages of high carbon fish rods

The higher the carbon rod contains the carbon rod, the lighter, harder, and stronger the pole, the more expensive the price, but the more crispy.Therefore, as a high -carbon fishing rod, what is pursuing a fast fish experience, it is more suitable for black pit fishing.Black pit fishing frequency is high, the fish individuals are relatively large, and there are many fishermen around them.Therefore, choosing a high carbon fishing rod during black pits can hold it for a long time, and quickly returning fish will not affect the fishermen around them.

But high carbon Fishing rods are not suitable for wild fishing.Wild fishing often runs east, the environmental conditions are complicated, and special attention needs to be paid to the use of Fishing rods.Due to its ultra -light and hard characteristics, the tip of the pole is crispy. In a complex environment in the wild, it is easy to cause the pole to break. Therefore, wild fishing is not suitable for high -carbon Fishing rods.

2. The advantages and disadvantages of low -carbon fish rods

The advantage of low -carbon fish rods is that we can catch catfish or carp.But the feel of the low -carbon fishing rod is not as good as the feel of the high carbon fishing rod.

The disadvantage of low carbon fishing rod is soft, heavy.Because the content of carbon cloth is low, the hardness and hardness of the fishing rod should be softer. It is more heavier. The Fishing rods we just used before were made of glass fiber fiber. It is characterized by strong, but it is hard. Now some low -carbon Fishing rods are just low -carbon Fishing rods.Mixed with carbon fiber cloth with glass fiber fiber.

Low -carbon fish rods rarely have broken rods when they are used normally. When we hear a broken rod, we are generally high -carbon Fishing rods. This is some of the errors in the process of materials and use.

Summarize:Suggestions when fishing: If it is for a target fish, then we can choose a suitable high -carbon fishing rod so that the feel will feel good when fishing, but when we fishing for many types of fish, we must choose to chooseA medium -carbon or low -carbon fishing rod, so that whether it is a large fish or a small body fish, it can be caught. Don't worry about the problem of Fishing rods.
