one,What is the standard size of the office Conference table?

The standard size of the Conference table is generally: 1200-1600mm in length, 500-650mm wide, and 700-800mm in height.The standard size of the Conference table is usually 1200*600mm, and the height is 780mm.The height of the Conference table is generally not very long and width. The height is generally not too high or too short. There are many size of the Conference table, and different sizes will represent people of different identities.Employees 'conference tables, supervisors' conference tables and boss's Conference table will have different sizes.There are also many materials at the Conference table. We commonly include stainless steel conference tables, wooden conference tables, glass conference tables, and so on.Which material Conference table is selected, which is matched with the company's entire decoration style and other employees' tables and chairs, and the style must be unified.

2. How to choose the height of the Conference table

The general Conference table is divided according to the head. There are five conference tables, about ten conference tables, twenty -person conference tables, etc. Different sizes are suitable for people of different identities to meet.

1. The size of the boss Conference table

The conference tables of ten to twenty are generally 3.8m*1.2m, 4.0m*1.2m, 4.2m*1.4m, etc. It is more common. In fact, this Conference table is also a customized Conference table for many small and medium -sized enterprises.EssenceThe conventional size of the Grandbank is unchanged, with a height of 0.75m. It is an ergonomic height. The width is 0.6m, 0.7m, 0.8m, and 0.9m. It is also matched according to the different length.1.6m, 1.8m, 2m, 2.2m, 2.4m of 2.4M are more conventional.

2. Missing Conference table size: about ten people, the meeting table

Generally, the size of the Conference table of six to ten people is 2.2m*1.1m or 2.4m*1.1m, and there are 2.4m*1.2m, 1.8m*0.9m, 2.0m*1.0m, 1.6m*0.8m, etc.Wait these sizes.

3. The size of the staff meeting at the staff meeting: the Conference table below five people

Generally, the size of the Conference table below five people is similar to the size of the dining table.The size is generally 1.8m*0.6m or 1.3m*0.4m, and the circular diameter is generally about 1.2m.You can choose different styles according to the office, whether it is a Conference table or a screen Conference table, the height is 0.75m unchanged, the conventional size of the table is 1.2m*0.6m and 1.4m*0.7m.The conventional size of 1.2m*0.6m, the conventional size of the L -shaped screen Conference table is: 1.2m*1.4m, and the highly conventional screen of the screen is 1.1m or 1.2m.

4. The size of the Conference table above 20 people

Generally, more than twenty -person conference tables are generally used by some larger companies, and the price of this Conference table is also the most expensive.The size is generally 6m*2m*7.8m, and 4.8m*1.6m*7.5m is a relatively smaller size.

Of course, the above size is not absolute. We can also have our own needs and the size of the conference room to make the Conference table size of these different number of people.

3. What material is the best material at the meeting table

1. The plate -type discussion table refers to the disassembly and combination table of the disassembly and combination of artificial board as the main substrate and the board as the basic structure.Common artificial boards include plywood, fine woodwork, particle board, mid -fiber plate, etc.

2. Planet (splint) is often used to make a Conference table that requires curvature and deformation; the performance of fine wooden boards is sometimes affected by the core material of the plate.

3. The particle board is also called a particle board and a slag plate. The material of the particle board is loose and is only used for low -end conference tables.

4. The most cost -effective and most commonly used is medium -density fiber board.The common surface materials of the plates are thin wood (commonly known as wooden Skin), wood grain paper (commonly known as stickers), PVC rubber, polycatic paint (commonly known as baking paint), etc.The latter three types of jewelry are usually used for mid -to -low -end conference tables, while natural wood leather jewelry is used for high -end products.The board Conference table is a Conference table made of medium -density fiber boards or particle boards for surface -to -surface processes.A large part of this Conference table is the wood grain simulation Conference table.At present, some board -style tables on the market will be more and more realistic. The luster and feel are good. The price of fine products is also very expensive.

5. Pure wood Conference table, which refers to the Conference table made of all materials that are not processed again, and do not use any artificial board.The pure wood Conference table has high requirements for craftsmanship and material.The requirements of solid wood selection, drying, fingerprints, and seams are very strict.If any process is not strictly controlled, the small cracked and loosening is occurred, and the large set of conference tables will be deformed and cannot be used.

4. How to choose the color of the Conference table

The color selection of the Conference table should be selected to the atmosphere. You can choose to choose vermiculous, cherry, and warm white. These colors look more spacious and atmosphere at the atmosphere of the meeting, so that everyone will not feel cramped.The decoration style of the same conference room should be matched with the color of the Conference table to play an integrated integration effect.

Fifth, which shape is good in the Conference table

First of all, the size and appearance of the Conference table requires the specific shape and size of the conference.Generally, in order to create a harmonious and equal communication environment, the Conference table should choose round or oval -shaped, which is more conducive to the meeting.At the same time, in such a harmonious environment, people can make people think more, speak freely, and help thinking innovation and team spirit.

If it is a formal meeting, then the rectangular Conference table is needed. People with different positions and different positions sit in different positions. This atmosphere of the meeting is difficult to activate, but it is even more serious and formal.However, it is still necessary to prevent the Conference table that appears in right -angle as possible, avoid punching evils, and avoid accidental damage to the body.

1. What is fast dry pants

Speed -dried pants are dried pants. It does not absorb sweat, but quickly transfers sweat to the surface of the clothes, and evaporates sweat through air circulation to achieve the purpose of fast drying.

The drying speed of general quick -dried pants is 50%faster than that of cotton fabrics.When outdoors, fast -drying clothes ensure that you are not uncomfortable when you get up in the morning.But one point, when you go out, bring a few pieces of clothes and put on dry clothes in the camp at night to avoid colds.

Second, the functional characteristics of dried trousers

1. Quick dry:The water absorption of fast -drying fabric is not high, has good breathability, and has a certain amount of water splashing. After being wet, under the action of body temperature or wind, it is relatively fast to dry the dryness of ordinary clothes and keep the body dry at all times.

2, breathable:Quick -drying fabrics can improve the air flow of the human high -the -rmal area, maintain the best motion status and comfort, the pants are lighter and soft, making the body Skin more relaxed and comfortable.

3. Anti -ultraviolet rays:Some quick -drying fabrics are treated with sunscreen, which can effectively block the invasion of ultraviolet rays, reflect some ultraviolet rays, isolate UVA and UVB to protect the Skin and prevent sunburn.

Third, Speed trousers fabric introduction

1. Polyester fabric

Advantages: Polyester fabrics are a lot of chemical fiber clothing fabrics used in daily life.Its biggest advantage is that wrinkle resistance and preservation are very good, and abrasion resistance is second only to nylon with the best abrasion resistance.

Disadvantages: Poor moisture absorption, dressed with sweltering, and easy to use electrostatic, dirty dust, affecting beauty and comfort.The disadvantages such as hard feel, poor touch, and not soft luster.

2. nylon fabric

Advantages: The abrasion resistance of nylon fabrics ranks first, which is many times higher than other fiber fabrics of similar products. Therefore, its durability is excellent.The hygroscopicity of nylon fabrics is a better variety in synthetic fiber fabrics, so the clothing made of nylon is more comfortable than polyester clothing.The nylon fabric is a light fabric, which is only listed in the synthetic fiber fabrics after the fibrine and acrylic fabrics. Therefore, it is suitable for making mountaineering clothes and winter clothing.The elasticity and elastic recovery of nylon fabrics are excellent, but it is easy to deform under small external force, so its fabric is easily wrinkled during the wear process.

Disadvantages: The heat resistance of nylon fabrics is poor. During the use of wearing, you must pay attention to the conditions for washing and maintenance to avoid damage to clothing.

3. High -tech function processing

Some stem trousers will also use some special high -tech functions, such as the global ScottGard process developed by 3M companies in the United States, which gives the organization very good oil -proof and polluting, making your quick -drying pants easily deal with all kinds of various typesThe harsh environment will always bring you easy and comfortable.In addition, some brands use the latest nano -microporous fiber technology. The inside of the fiber is designed with "Honeycomb" Nobunaga, which will automatically adjust according to the temperature and temperature of the human body.When the human body sweats, the water vapor will directly distribute through the micropore, and the remaining part of the liquid will be quickly absorbed by high -density micropores close to the Skin, and the high -density micropores outside the fabric will spread and evaporate quickly, making the body feel good at all times.Comfortable.

1. What does shoes culture mean?

The origin of shoes can be traced back to the early 19th century and is a product of technological progress and social change.In that era, not everyone could perform sports. Having a pair of sneakers that could improve sports performance were a reflection of superiority.People prefer tennis during this period, and the maturity of rubber technology has promoted the popularity of rubber bottom canvas shoes.tennis was a noble movement during this period, and rubber bottom canvas shoes naturally became a symbol of social status.

Fascism, which appeared in the 1930s, caused the general public's pursuit of perfect body, and the development of technology allowed sneakers to achieve civilian sneakers through this opportunity.

In the 1950s, television entered millions of households, which was an important opportunity for the rise of sneaker culture.Many sports stars and their shoes they wear have become the goal for people to chase.With the popularity of these sports stars, various sports gradually have their own exclusive sneakers, and the sneaker market has begun to be subdivided.

In the 1970s, American basketball shoes culture began to transform into a cultural symbol.During this period, there were two major events: Nike signed a basketball newcomer Michael Jordan, and Adidas signed the black rap band run-DMC.These two things pushed basketball shoes to a wider audience, and also led the trend of street sneakers around the world-that is, the so-called sneaker culture in the 1980s.

The meaning of sneakers

1. The indispensable part of basketball career

Provide protection for you, support every ball that supports you, whether it is victory or failure, it always participates, such as a friend, companion, listener, not simply meaningless with meaning.

2. It is a culture, a spirit

When the sneakers are given a mission, you will carry your basketball dream and go forward along the way.Playing balls you like, you will feel practical and more confident.Because of its special existence, sneakers are not just as simple as sneakers.It is a symbol, a witness you want to fight for it.

3. It is also a kind of sustenance, which is the continuation of basketball dreams

Reality is always reality. After work, many people really can't think of playing unrestrainedly like that before.And sneakers are lingering dreams.Even if you haven't played for a long time, even if your ball skills have plummeted, even if you feel at all, when you re -put on the sneakers and go to the court, the familiar feeling will come back, and all the troubles in front of you will disappear.You will think of how obsessed you are, how fascinating basketball.From morning to night, there is no problem.You will think of how you used to be progressive.Those lost balls are in sight, and you don't want to let it happen again.You will think of yourself, have a group of iron brothers.Playing with calls, those days when skewers are grilled and talked about each other.You will think of the past, and you meet her because of basketball.

shoes, it is such a special existence, a kind of emotional sustenance.

3. Getting started with sneakers

Sneaker disassembly

Here, shoes refer to general sports shoes, because the types of sneakers are different, and the design is very different.In general, sports shoes are divided into two parts: upper and soles, and the soles are composed of three modules: inner sole, midsole, and large sole.Due to the different versions, the names of each module are slightly different. Generally, a pair of sneakers consist of the above parts. Next, look at the role of each module.

1. Toe: Protect your toes.

2. shoes bile trimming: breathable.

3. Belt: protect your feet and fix.

4, tongue: protecting the back, fixing, wrapping.

5. Rear follow -up film: Avoid hurting Achilis tendon.

6, rear block: stable heel.

7, ankle foam: protect the ankle and comfort.

8. Inner bottom and insoles: evenly distributed foot pressure, support, and sweat absorption.

9, midsole: shock absorption, energy rebound.

10. Bottom: non -slip and wear -resistant.

Sneaker technology

A pair of sneakers, with excellent shock absorption function and rebound ability, even excellent.However, from the perspective of biomechanical characteristics, sneakers need to consider 6 latitude such as shock absorption, elasticity, bottom pressure, grip, reversing, and stability.

Sneaker term

1. OG = Original: The first year color scheme, that is, the original classic color matching of the shoes.Retro refers to the re -engraved version.

2. HIGH: Gang Gang, MID: Mid -Gang Low: Low Gang Edition

3, AC: vulcanized rubber reinforced outsole material, BR: breathable mesh material, SUEDE: suede material, LTR = leather: leather material, LUX: high -end luxury version.

4. CL = Classic: Some shoes will be subdivided into three Levels. C is the basic version of them, and it is usually a retro ball style of Nike.

5. PRM = Premium: The high -end version, that is, the level of one level higher than C, workmanship, shoe lining, etc. are more detailed. The shoelaces usually use the metal head.

6. Sprm = Supreme: The top version will be the highest specifications of this shoe. You can see more exquisite designs, usually the price is the top.

Telescope Buy Young Specialty Professional Profession

Telescope choice

Purchase by the environment

If you think of travel at sea or seaside, don't forget to buy a waterproof Telescope.

If you want to go out for tourism, you can buy a small Telescope with a small volume.

If you intend to go to the dangerous areas that can be seen from a distance but not to detect ", you should buy a high -multiples Telescope.

If you want to hunt or travel for a long time, it is best to buy a variable multiples Telescope, which shows how it uses it.Because the changeable Telescope can be gradually adjusted from the low multiplier to the high multiplier, the low multiplier and large field of view should be used for roughly when used, and then carefully observed with a high multiplier and small field of vision.

What are the terminals?

caliber

This is the most important factor when choosing an astronomical Telescope. The primary function of the Telescope is to collect light. No matter how much the magnifying magnification, the better the imaging.The diameter of the Telescope is to expect the glass diameter of the remote mirror or the main lens size, which is represented by millimeters or inch.The greater the diameter, the stronger the ability to collect light, the better the imaging.The larger the diameter, the clearer the details of the picture. For example, when observing a spherical nebula of a M13, a 4 -inch caliber Telescope needs to use 150 power supply, but the 8 -inch caliber Telescope also uses the same ones with the same ones.Power, but Nebula images are 16 times clearer than 4 inches.Even the stars under the weak light can be seen clearly.Considering that the user needs a long -caliber Telescope as much as possible, a large -caliber Telescope.The photos taken by a large -diameter Telescope have higher contrast, better resolution, and clearer.The Cyruster Telescope has "5 -inch caliber", "8 -inch caliber", "14 -inch caliber".

Discerning ability

This involves "Douas restrictions".The distinction between two tight twins, theoretically the ability to distinguish the Telescope is determined by 4.56 to remove the caliber of the Telescope.For example: a resolution ability with a diameter of 8 -inch is 0.6 (4.56/8 = 0.6) that directly affects the distinguishing ability of the Telescope is the caliber of the Telescope. Therefore, the larger the Telescope, the better the resolution ability.However, the ability to distinguish also depends on the influence of the atmosphere and the acuity of people observing objects.

Pupil diameter

The diameter of the pupil is a circular beam that appears in the case of a Telescope without eyepiece, which is represented by mm (millimeters).Calculate the diameter of the pupil, for example: a Telescope with a diameter of 8 inches (203mm), uses a zoom distance of 20mm eyepiece to place 102 times large, and the pupil diameter is 2mm (203/102 = 2mm).Or you can also use the focus of the Telescope to remove the diameter of the pupil with the focal length of the eye mirror.

Extreme Star et al.

Astronomers use a star and other systems to explain the level of bright stars. A star body is considered to have a certain star. The higher the level, the darker the star.The value of the stars) is about 2.5 times the stars. The darkest star body that you can see with your naked eye is about six -class stars (in the night sky). On the contrary, the brightest star is 0 and the stars (orEven negative values).See the darkest star body with a Telescope (the best time in various environments), that is, the extreme star, etc., the extreme star, etc. directly depends on the caliber of the Telescope.EssenceRoughly calculating the formula of Extreme Star is: 7.5 5 LOG (represented by CM).For example: The extreme star with a diameter of 8 inches is 14.0 (7.5 5 log 20.32 = 7.5 (5x1.3) = 14.0).The situation of the atmosphere and the visual acuity of the observer will have an impact on extreme stars.Shooting extreme stars is about two or more than visual limit stars.

Vision

The range you can see when you observe the sky through a Telescope is the field of view, which is represented by an arc angle.The larger the view of the field of view, the greater the observation range. The calculation formula of the perspective angle is that the perspective angle of the eyepiece used is except the finger of the magnification of the Telescope.For example: If the eyepiece you use is 50 degrees, and the Telescope used with the mirror and the magnification of the eyepiece is 100X, then the visual field of the Telescope is 0.5 degrees (50/100 = 0.5).Born manufacturers usually specify the corners of their eyepiece. In general, the larger the viewing corner, the larger the view of the field of vision, because the more you see when you observe the starry sky. In addition, the more, Using a low -magnification astronomical Telescope is wider than seeing the high magnification.

[Types of Sunglasses] What are the types of Sunglasses?

What are the types of Sunglasses

When buying Sunglasses, many friends do not know which type of Sunglasses they need, simply pay attention to the ranking of Sunglasses brand, and choose according to their preferences.eyes, you need to take more care, so you should know more when choosing Sunglasses and less blind.What kinds of Sunglasses do you know?Let me introduce you in detail.

The Sunglasses can be roughly divided into the following:

1. Anti -light protection lens

This kind of lens can prevent strong light reflexes, allow you to see things from being disturbed in strong light, and clearer.The principle of this lens is actually very simple, that is, a layer of magnesium is applied on the surface.If you want to know if your Sunglasses are used in anti -light protective lenses, you can align the glasses at the light source. When you see the purple or green reflection, it means that there is a protective film on the lens.

2. color lens

This kind of lens is also called "dyeing lens". The Sunglasses using this lens can absorb the light of a specific wavelength. The principle is to add some chemicals during the lens production process to make the lens appear color.This lens is the most commonly used by Sunglasses.

Third, coloring lens

This kind of lens is actually the same as the color lens, but this kind of lens is generally used in a degree of Sunglasses. Among them, everyone is most familiar with "gradient -like coloring lens". The color is from top to bottom.From deep to shallow.

Fourth, polarized lens

The word polarization is used a lot in Sunglasses, but many people do not understand the specific meaning. In fact, this kind of lens is to filter the dazzling light emitted by the sunlight in an equal direction, and add vertical special coatings to the lens.outdoor sports (such as: maritime activities, skiing or fishing) are very suitable for use.

Five, color change lenses

Another name is "photosensitive lens".Originally transparent and colorless lenses, when encountering strong light, it will become a non -colored lens to protect the eyes. This is because this type of lens is added with silver chemicals.It is very suitable.

Sunglassesprecautions

If you understand these aspects, you can help when you buy Sunglasses. After buying, you must take care of your beloved Sunglasses!
