How to use the Telescope and maintenance skills

Many people have Telescopes, and even many friends have military Telescopes. Although they have such good things, many people do not know how to use them and how to maintain them. Today, they answer questions for everyone.

How to use the Telescope:

1. Adjust the distance of pupils

First of all, my Telescope is a rotating eye mask system. When used, the eye cover is rotated to the highest (generally operating this). If you bring glasses or when you are at the highest of the eye maskShadow (shadow), you need to adjust the eye cover to the most comfortable height of your glasses.

Second, adjust the distance between the program

Change the distance between the Telescope two lens cylinders, until the left and right views are a circular viewing field.At this time, the pupil distance of the outlet of the two lens cylinders was consistent with the two pupils of the human eye.

3. Focus

First rotate the middle -tone agency's handwheel of the Telescope until the left eye can see the target clearly.Then turn the vision of the right mirror, so that the right eye can also see the goal.

Fourth, observation

The Telescope is roughly observed to observe the goals, and the central institution is turned, and the eyes can quickly see the target at the same time.For different distances, as long as you rotate the central institution, you can see it quickly.

Notice:

With Bi, the rotary eye mask must be put down back, otherwise it may hit a bad rotation eye mask because of negligence.

Because of the focus function of the Telescope, it is not suitable to observe the bright objects, especially the sun, which will damage your eyes.

maintenance of the Telescope:

1. Do not wipe the mirror or eyepiece mirror with other ordinary cloth, use the velvet cloth or other soft cloth to wipe the Telescope mirror mirror with a Telescope bag.

2. When removing the residual dirt or stains, you can drip one or two drops of alcohol. It is best to use a cloth to dip, because the drip is not easy to control.

3. Although everyone buys a waterproof mirror, there will be no use problems even if they fall into the water.But in terms of maintenance Telescopes, preservation Telescope in a dry environment is harmless to the baby's coating and Telescope.Waterproofing and nitrogen -filled functions are only in case of water falling and moisture, and they are not afraid of being subject to moisture.

4. Don't try to clear the interior of the Telescope or disassemble the Telescope. The Telescope is actually very complicated. The light shaft is broken on the dedicated to debug the light shaft of the Telescope to debug.As soon as the Telescope is disassembled, the light shaft will change, so that the imaging of the left and right Tube will not be overlapped, making your glasses uncomfortable, and in severe cases, you cannot use it at all.Do not fall, pressure or other severe actions of the Telescope, mainly because of the light shaft of the Telescope, and it is easy to destroy any glasses in the light shaft of the Telescope.Please send it to me, help you repair it for free.

5. Do not observe the sun directly with a Telescope. This is a major precautions of all Telescopes. The strong sunlight through the focus of the Telescope, just like a magnifying glass, will burn your eyes.

6. Due to cost and self -weight, carry light consideration, most of the current Telescope is not a metal mirror body. It falls heavy, heavy pressure, and it is easy to damage.So everyone should love her like a Dog.

7. The desiccant I match is actually not meaningful to the waterproof Telescope. After a year, I will be thrown away.However, it is best to replace it regularly (half a year to one year) to prevent the internal moisture.The desiccant should be available, and some products are also available, which can be borrowed.

8. After using the baby, first look at the foreign body on the table when placing it. Do not place it on other items to prevent scratching or staining mirrors and eyepiece.

9. The Telescope still should be put on the drip. Do not put the eyepiece down.(Everyone on the earth!), Because some parts are painted with lubricating oil, and some places are designed with oil grooves. For a long time, the inverted time or the weather is too hot, and it may flow to the place.

1. What does infrared Telescope mean?

There are many types of infrared. Most of the microcariar night vision also have infrared functions. Its infrared is a short wave infrared, which is longer than visible light, similar to remote control.The purpose of this night vision design is to use infrared lighting, so it is not easy to be discovered (enemy).There is also a thermal imaging. Thermal imaging actually collects the infrared from collecting hot objects. However, this infrared wavelength is very long, and the general microcariae night vision instrument cannot be seen.The advantage of thermal imaging is that it can effectively observe the heat source, such as mammals, cars, etc., which is very useful in military.

2. Principles of Extramaginal Telescope Imaging

You can see the infrared Telescope, which is the band of infrared rays((wavelength8001 000Nm)The Telescope.It is also one of the night viewing Telescopes in military applications.Of course, the infrared Telescope is applied to astronomical observations.The infrared Telescope converts the infrared rays into electronic flow through photoelectric transformation, and then doubles the electrons. Finally, the electrons are hit on the fluorescent screen and turned into visible light.As long as there is temperature, infrared rays will be generated, he is a special lens that can pass and display infrared rays.

3. How much is the infrared Telescope

Like the movie, you can see the enemy clearly at night without light. Only the military active infrared Telescope.Russia is cheap and good quality. Among them4800RMB, if you can buy it in China, it should be in6000above.If it is lower than5000The active infrared night viewing Telescope should be a bit problematic. It is recommended not to buy.

4. Can infrared Telescope be seen through?

cannot.Because our human body has body temperature radiation.No formal manufacturer's manual says that I am"Perspective Telescope".Only said it is night vision Telescope.

Fifth, the red film Telescope is the infrared night vision mirror?

The Telescope, not to mention civilian, military useless Telescopes of night vision, the movie is just a movie.For red or yellow coating, many illegal vendors publicize that "night vision effects, infrared" and the like are actually false propaganda.It is a kind of decoration -has no night vision effect. In fact, this decorative coating also makes the field of vision dark.So except for the previous processed samples, other red film products have not been provided.Although the Telescope of red film, although the brightness and color deflection are not as effective as other coating, because the appearance is good, even as a regular military industry (foreign trade) manufacturer, there are a small proportion of exports.But the problem is that in the domestic chaotic Telescope market, most of the red and yellow -coated Telescopes are not from such regular manufacturers, but some small workshops, in order to deceive the propaganda (so -called "military"/"Russia",/"Japanese cherry blossoms"/"night vision"/"infrared") produced, that is, most of them are inferior products of small workshops.

What are the fabrics in the Swimsuit

1, Du FangLaika

Du FangLycra is a artificial elastic fiber with the best foam of elasticity. It can be freely extended by 4 to 7 times. Extension is excellent.Suitable for blending with a variety of fibers, which can strengthen the advantages such as drooping texture, anti -wrinkle and other advantages.DuPont Ledica, which contains anti -chlorine, will make swimwear a longer service life than a Swimsuit with ordinary materials.

2. nylon fabric

The fabric obtained by blending or interweaving the nylon long silk or short fiber and other fibers has the characteristics and strengths of each fiber.For example, the sticky/Jinhuada, using 15%nylon and 85%of the adhesive blending into a yarn, which is doubled by density than weir dense.Wrinkle, dampness drops, and it is easy to droop when wearing.In addition, there are varieties such as sticky/Jin Fanling, sticky/brocade/hair, etc., all commonly used fabrics.

The most common nylon products in the market are nylon 6 and nylon 66.

nylon 6: The full name is polybioneam fiber, which is concentrated by the amide.

nylon 66: The full name is Ji Ji gyacinhamine fiber, which is concentrated from the gimysic acid and the hexyramine.

The common characteristics of nylon 6 and nylon 66: Poor photosyntynce resistance. Under the long -term sunlight and ultraviolet light, the strength decreases and the color is yellow.Huang, intensity and extension decreased significantly, and the contraction rate increased.

nylon 6 and 66 long silk has good low temperature resistance. When it is below minus 70 C, its rebound changes are not great.Its DC conductivity is very low, and it is easy to generate static electricity during the processing process. Its conductive rate increases with the increase in moisture absorption, and increases according to the index function rules with the increase of humidity.nylon 6 and 66 long silk has a strong ability to resist microorganism. Its ability to resist microbial effects in mud or alkali is second only to chlorine.In terms of chemical properties, nylon 6 and 66 long silk has the effects of alkali resistance and reducing agent, but has poor performance in acid resistance and oxidant.

3. Polyester fabric

Polyester fabrics are a lot of chemical fiber clothing fabrics in daily life.Its biggest advantage is that wrinkle resistance and preservation are very good, so it is suitable for coats.

Polyester fabrics have poor moisture absorption, dressed in stuffy, and easy to use electrostatic, dirty dust, affecting beauty and comfort.However, it is easy to dry after washing, and the wetness is almost not reduced, does not deform, and has good washing performance.

Polyester fabrics have high strength and elastic recovery capabilities. Therefore, it is firm and durable, anti -wrinkle and refractory.

Polyester fabric has a good light resistance. In addition to the worse than acrylic, its sun resistance is better than natural fiber fabrics.Especially the ability to resist behind the glass is very good, and it is almost comparable to acrylic.

Polyester fabrics are resistant to various chemicals.The degree of acid and alkali is not greatly damaged, and they are not afraid of mold, not afraid of insects.

Polyester is the best thermal resistance in the fiber fabric. It has thermoplasticity. It can be made of pleated skirt and long -lasting.At the same time, polyester fabrics have poor anti -melting properties, and they are prone to forming holes such as ash and Mars.Therefore, we should try to avoid contact with cigarette butt, sparks, etc. when wearing.

1. The difference between outdoor down jackets and ordinary down jackets

1. Different fabrics and functions

(1) Ordinary down jackets use coating fabrics with high -density silk, cotton, cotton polymes and other fabrics, which are treated by rolling, which reduces the gap between the latitude and weft gauze.The transparent Skin covering layer of the intercourse chain is to close the latitude and weft gaps of the fabric, which has the performance of anti -dewl velvet and water -proof water.

(2) outdoor down jackets Due to some special environment requirements, fabrics are generally treated with special treatment. Compared with ordinary down jackets, it improves warmth, waterproof, and windproof.The effect of splashing water is better.

2. Different weight and compressionability

(1) outdoor down jackets are pursuing lightweight, that is, the lighter the wear.So the Outdoor light down jacket is lighter than ordinary down jackets.Some down jackets have hardly felt the existence of clothes on their bodies.It is also very convenient to compress, and it does not take up space in the bag.

(2) Ordinary down jackets are wearing daily, without considering the problem of load and compression.

3. Different down down

(1) Ordinary down jackets can improve the warmth of the clothes and improve the diamond velvet performance by filling more quality down and thick fabrics. Therefore, it is still possible to keep warm in daily down, but it is less comfortable for Outdoor use.It's right.

(2) outdoor down jackets are usually used with down 600 or more down. High -end ones are 800 puffs, which are light and warm enough to wear.

5. Drilling the anti -drill velvet effects different

(1) Most of the ordinary down jackets are mostly high -density coating fabrics, which have good anti -drill velvet effects.

(2) outdoor down jackets usually consider the breathability of clothes. The disadvantage is that the probability of down the down jacket in the thinner of the feller is much higher than that of the normal down jacket.

2. Which one is the best of outdoor down jackets and ordinary down jackets

The most important thing for buying down jackets is to figure out the actual use. If it is simply used for cold protection, you can choose ordinary down jackets. If you are in an Outdoor extremely cold area for a long time, of course, it is better to choose a professional Outdoor down jacket.

1. Do you want to hit the home improvement Wall cabinet?

1. The advantages and disadvantages of the Wall cabinet to the top

advantage:

(1) It is undoubtedly to increase the storage area to the greatest extent, which is very practical.

(2) A whole cabinet makes people feel more beautiful.

(3) If you do the top, you will not worry about it will be ashamed, so it is more convenient to do it.

shortcoming:

(1) Since the cabinets are all plates, wood is easily moisture, especially when placing by the wall, it is wet. Once the heat is swollen and contracted, the cabinet volume will increase.The space is because it will lead to increased load load, which will cause deformation and affect the service life of the cabinet.

(2) If you hit the top, it is very troublesome to take Dongxi, and the short ones cannot be obtained.

(3) The cabinet is hit to the top. If the room space is great, if the space is small, it will make people particularly depressed, especially the kitchen!

2. The advantages and disadvantages of the Wall cabinet do not hit the top

To a large extent, the advantages and disadvantages of not playing to the top are just the opposite of the above.At the same time, you can save money on the top, but it is easy to hide ash, and the cleaning is more troublesome.So how to overcome the shortcomings that do not hit the ash?

(1) The ceiling is sealed with gypsum board so that there is no empty space over the cabinet, and it will not hide the gray.

(2) Put a storage box or storage basket above the cabinet, which can effectively use the air area and avoid the ash.

Second, how much is the Wall cabinet a Square Square meter

There are two calculation methods in the market on the market: one is the projection area algorithm, and the other is the development area algorithm.

1. Projection area algorithm: The projection area algorithm of the wardrobe is the simpler of the two algorithms.Customized wardrobe projection area: wardrobe width x wardrobe height = projection area, projection area X wardrobe unit price = wardrobe price.If a wardrobe is 5 meters, the height is 2.8 meters, and the unit price is 1,000 yuan/Square meter. The price of this wardrobe is 2x2.8x1000 = 5600 yuan.

2. Expand area algorithm: The wardrobe area algorithm is more complicated than the projection area algorithm.Calculation according to the area of the wardrobe is calculated based on the board used in the cabinet.That is, when the consumer finish the size of the merchant, and then produce a good wardrobe design plan, and determine the plan, the merchant spreads the calculation of all boards used by the consumer to determine the plan.The unit price of the plate with different thickness of the plate of the board = the price of the wardrobe.(No other functional accessories)

Although the price algorithm of this customized wardrobe is more troublesome, the price of various materials is clear, but it is fair and fair for consumers.Consumers can choose the internal pattern of the wardrobe according to their own habits to control the budget, and the price is more transparent.
