1. Do you need to wear ski gloves for skiing?

You need to wear ski gloves during skiing.The temperature is low during skiing, and sometimes it can even be less than minus, so you need to wear thick gloves to keep warm to prevent your hands from frostbite.Moreover, during skiing, if you fall or hold the snowboard, having gloves can reduce the possibility of hand injury.

2. ski gloves Five fingers are good or even better

ski gloves are usually divided into five -finger separate type and joint gloves.ski gloves have the advantages and disadvantages of the five fingers and even the even fingers. Which gloves should be determined according to personal needs and preferences.

The advantages of five -finger gloves are flexible, suitable for holding snow sticks when double -board skiing, and it is also suitable for adjusting fine finger movements such as snow tools and snow shoes.In addition, five -finger gloves can also provide better touch and hand control, which is conducive to fine operation.However, the warmth of five -finger gloves is not as good as finger gloves.

The advantages of even finger gloves are excellent heating, suitable for skiing of the board, and can also provide additional safety protection.However, the flexibility of the gloves is low, and it is not suitable for holding the snow stick or performing fine finger movements during double -board skiing.

Therefore, when choosing ski gloves, decide according to personal needs and preferences.If it is skiing in cold winter and staying outdoors for a long time, it is recommended to choose a finger glove to keep your hands warm.If you are skiing in a warm season, or you need to perform slight finger operations, you can choose five -finger gloves.

A suitable ski gloves must be close first, and leave enough space at the end of the fingers.At the same time, reinforcement will be adopted in the palm, fingertips, and thumbs to better hold the snow stick.Be careful not to buy wool gloves, not waterproof or warm.

[yoga mat] What is the size of the yoga mat in yoga mat?How to buy Yoga mats

How to buy Yoga mats

As far as the yoga people are concerned, it is a necessity of daily life.The longer the yoga people who practice yoga, the more they like to bring their own Yoga mats.Because a fashionable and beautiful yoga mat, not only can you get more likes in the circle of social friends, but more importantly, you can also ensure the continuity of practice in the yoga hall, journey and home.

Therefore, choosing a yoga cushion that suits you has become a must -have homework for yoga people.Next, we mainly analyze how to choose yoga cushions from the positive lines, materials, size, portability and non -slip.

oneAs well asPositive line

This is the most important detail standard for yoga people to choose cushions.The positive lines on the pad can guide the assistant practitioner Xi Lian's more accurate and more accurate yoga.The choice of positive lines is basically grasped two points: First of all, it depends on the design principle of the lines (that is, the authenticity of the system).It is more accurate to fit)

2. What are the materials of Yoga mats?

At present, the mainstream Yoga mats on the market are generally divided into PVC, TPE, natural rubber, cotton, cotton, and mixed material Yoga mats.If you are allergic to latex, pay attention to whether you are not included in the latch-free in the scoring label.

PVC

Advantages: good durability and low cost of raw materials, so the price is relatively close to the people, and it is also currently using relatively common Yoga mats; it does not contain latex, suitable for gathers who are allergic to latex; material absorption is poor, so it is easy to clean.

Insufficient: Because the material absorption is poor, the non -slip resistance is good under drying, but for the sweaty people, the wetting and slippery properties are poor; plastic products cannot be degraded naturally.

TPE

Advantages: high elasticity; good/wet and anti -slip; environmental protection, some products can be completely recycled.

Insufficient: Compared with PVC, durability is poor.

Natural rubber

Advantages: raw materials are natural and environmentally friendly; surface natural texture and opening structure can help absorb moisture. Therefore, it is very good regardless of the anti -drying or slippery effect.

Insufficient: The smell is heavier when it is bought; the opening structure is easy to absorb stains and requires market cleaning.

cork

Advantages: environmentally friendly and non -toxic, almost no odor; wood is more back to nature; anti -drying and slippery effects are excellent.

Insurance: The price is relatively expensive; the wooden structure is well absorbed and it is not easy to clean.

Cotton

Advantages: Skin -friendly and non -irritating, is the first choice for love for traditional preparation craftsman; easy to clean.

Insufficient: The effect of the grip is poor, which is limited to yoga courses or meditation exercises with less movement, which is relatively niche.

Mixed material

Most of the synthetic materials of chemical industry are non -toxic -free products.In the modern sense of industrial assembly line, Yoga mats are the first to use PVC as materials.

TPE is a relatively high -end material, with high production quality and friendly environment. It is currently the most commonly used public pads in mid -to -high -end gyms.

threeAs well asHow much is the size of the yoga mat

The length is usually in163cmand183cmLeft and right; width is usually in61cmabout.

Beginners can choose according to the material,TPEAs well asPVCRecommendation6-8mmMedium thickness, natural rubber recommended use4mmThe left and right can make the process of first -school yoga more pleasant;

Advanceder recommendation3-6mm(Also the most common thickness on the market), gradually adapt;

Senior person recommends use1.5-3mmThin pads, fully perceive the ground, and keep the movements stable.

FourAs well asPortability

yoga people usually prepare two mats, one placed home, and one for Outdoor exercises.The yoga cushion at home can be ignored, but the cushions that are brought out must be easy to carry.First of all, the weight is light, and many brands will produce1.5-3mmYoga mats for travel can be rolled up or folded very conveniently, put in a suitcase and Backpack.

fiveAs well asNon -slip

Friends who just come into contact with yoga, in addition to choosing a positive yoga cushion that can help you develop good habits, you must pay most attention to the problem of anti -slip cushions.Stress, difficult to obtain stretching, in addition to the correct practice of constitution, it is also related to the safety of training.summer yoga is easy to sweat. At this time, a cushion is needed.

The most important point of choosing a yoga mat is to be soft, the ground, and the grip should be strong when the floor is paved. You cannot slide when sweating. It is best to carry it.Secondly, there must be good waterproof and non -slip performance.Even sweaty can practice on it.

Xiaobian suggestion

1Use the thumb and index finger to pinch the yoga mat, try the resistance of the pressure, good elastic Yoga mats have a more protective effect on the human body.

2, Come with a rubber rubbing before buying, wipe the yoga mat with it, try whether the material is easy to breakWhat's more?

3Push the surface of the cushion with the palm of your hand, you need to have a dry feeling. If the cushion surface foaming agent remains too much, it will have a slippery feeling, then it is easy to slip and fall when you do exercises.

4The practitioner of the first yoga can choose a thicker pad, such as6mmThick;;If you have a certain foundation, you can choose thickness3.5mm-5mmThe left and right Yoga mats.

5, Compared to traditional usePVCThe produced Yoga mats, mixed natural latex and environmental protection Yoga mats, although the price is slightly higher, it will be better for the human body and the environment.When economic permission, you may wish to consider it.

1. The anchor fish hook is stabbed upside down or there is no stabbing

The anchor Fish hooks are divided into pheasant Fish hooks and no pouring Fish hooks. The inverted thorns are generally located on the inside of the hook tip, and there is a certain torment.Generally, the same brand and the same type of Fish hooks will have a fish hook with piercer and no thorns.

1. The advantages and disadvantages of pouring Fish hooks

(1) advantages

Due to the existence of stabbing, the pouring anchor hooks are not caused by the presence of pyromics, even when we choose earthworms, insects and other live bodies as bait, we will not fall off due to their struggle and peristaltic.In the actual fishing process, after the fish hook smoothly stabbed the fish, due to the existence of piercer, it can also reduce the risk of fish falling off, thereby reducing the decoupling rate of our fishing.

(2) Disadvantages

When the fish hook has a stabbing, the fish may have a certain sense of obstacle when they eat, so that the fish cannot swallow the hook smoothly.Because of the existence of piercer, when we lift the pole and spine fish, there will also be a certain resistance. At the same time, when we want to remove the fish hook from the fish, we need to fix the fish first.It takes a certain amount of time when picking up hooks.And during the fishing process, it is inevitable that the fish hook will be hung to clothes or pants, or when the fish is copied with the fish, the fish hook will hang the net. At this timeIt is difficult for us to take out the fish hook smoothly.

2. The advantages and disadvantages of no pierced fish hook

(1) advantages

There is no obstacle to the piercing fish hook. It is more conducive to the fish swallowing bait and biting the hook. It is smoother when the fish is thorny. When the hook is taken, there is no need to fix the fish first with the hand to pick up the hook.Just hold the fishing line to touch the fish to the edge of the fish, and the fish will easily fall into the fish protection.Because the fish hook does not pour, even when the fish hook hangs on the clothes, fish care and other objects, it can easily remove the fish hook.

(2) Disadvantages

Because there is no thorns on the hook, the live body such as earthworms, insects, etc. cannot be used as bait, because when they are motivated or struggling on the hook, they do not have the restraint of the piercing. They are easily dropped.In the choice of bait, there is no pierced fish hook suitable for plant or commercial bait.At the same time, when the fish hook is not spiny, if we are loosening in the process of fishing, the fish can easily break off the fish hook.

Second, there are applicable scenarios of inverted Fish hooks and no piercing Fish hooks

1. Applicable scenarios with pouring Fish hooks

During leisure fishing, the fishing environment is relatively complicated, the fish mouth is relatively sparse, and the choice of fishing and bait is rich. Therefore, there are pouring Fish hooks for leisure fishing.

2. Applicable scenes without piercing Fish hooks

When competing fishing, the fishing environment is relatively simple and convenient. In order to have better fishing results, the fishermen are also necessary to fight in seconds.Commonly used for competitive fishing.

Third, how to remove the pheasant of the fish hook

If you do nt want to use a fish hook with pouring spines, you can directly tell the owner of the Fishing gear shop that you need to buy a pouring fish hook. If you accidentally buy it, you can remove the piercing: prepare a knife or an ordinary nail knife.Insert the hook with the pheasant part into the blade blade, hold the handle gently in the right hand, and turn the fish hook at the same time, so that the pouring spines on the fish hook can be removed.

What to think of the Telescope multiples

The multiples of the Telescope are the previous number, and the latter number is a plympite diameter.These two numbers have no specific effect, which is two separate parameters.

For example:20X22 Represents the multiplier 20 Be more, the aperture diameter is 22mm Essence

The larger the Telescope multiples, the better, the better

The multiple of the Telescope is theoretically inversely proportional to the visual field of the Telescope. The higher the multiple, the smaller the view.Therefore, the multiples of the Telescope are not too large.50mm The diameter binocular Telescope, if it is here 20 The double is basically the limit. If the multiple is large, the field of vision is too small.It is basically impossible.

Common multiplayer of the Telescope

Common7 Double 8 Double 10 Times. 12 The higher or even higher Telescope does not have technical difficulty, but if you do not need a tripod, you will be able to see anything.

Maximum multiples of the Telescope

1 There is a standard multiple range of holding Telescope, that is, 7 ~ 10 Between times, the range of this multiple is obtained through long -term practice.

Because the higher the multiple, the better, while increasing the multiples, it will also cause problems such as narrow vision and jitter.

2 , "The highest", in fact, the highest ones are 20 Double, 16 Double, 12 More, but there are no such products. What are such products?They are all deformed and low -end, rely on multiple to seduce products of consumers who are not familiar with Telescope.

Shipped Telescope purchase suggestion

Watching the scenery, double Tube6 ~ 8 The best, the eyepiece 32 ~ 42 Between the backblasses.

In the case of stargazing, double Tube8 ~ 12 The best, the eyepiece mirror 42 ~ 50 Between the backblasses.

Paul mirror is not recommended, because the same caliber, the gyrolasses are much lighter than Paul mirror, which is more suitable for handheld and shake.

Not recommend50 The above is also considering the weight, 50 Even if the above ridge is needed 1kg If you hold it, it will inevitably shake.

What to think of the Telescope parameter

The magnification of the Telescope: that is, the magnification (multiple) of the Telescope is a magnifying multiple through the Telescope observation target.It is equivalent to observing objects at 100 meters with the naked eye. Its value is equal to the ratio of the focal length of the object mirror to the focal length of the eyed mirror.

The caliber of the Telescope:Here refers to the diameter of the objective mirror. It is usually expressed by mm. For example, 7X50, then it means that the diameter of this Telescope is 50mm.

The focus method of Telescope:In general, there are two types, one is the intermediate focus, that is, by rotating the focus wheels in the middle of the mirror body, the appearance of the two eyepiece is gradually clear.There will be a separate coke wheel on the right eye mirror of some Telescopes. This is because the eyes of the two eyes may not be the same vision, so you can adjust the right eye alone.The coke wheel, open the right eye after the left eye is clear, and then open the right eye. After the right eye mirror is adjusted to adjust the right eye mirror alone, the eyes are clearly debugged, and the intermediate focus wheel can be adjusted uniformly.

The other is to focus separately, that is, close the right eye to debug the eye mirror of the left eye alone. After the debugging is clear, close the left eye to adjust the right eye mirror alone. After debugging the clear debugging, you can enjoy the beautiful scenery.

Prism system:Now the mainstream Telescope prism system uses two basic designs: ROOF prism or Porro (also translated Porro, Poparo, Baoluo) prism.

The roof spine prism system is that the optical structure is relatively light and compact, and it is more suitable for outdoor sports portable products; the disadvantage is that the light losses are more and the imaging is relatively darker (but with the development of coating technology, the imaging effect of the Telescope of the roof structure is greatly great.Improvement), high requirements for assembly accuracy, difficulty in manufacturing, and expensive prices.At the same time, the appearance is much more complicated than the Paul prism, and it is difficult to process. In addition, it is difficult to be more difficult to assemble and maintainability, so the cost is high.

Paul prism is also called right -angled prisms. It is a traditional classic design. The more common design is composed of two exactly the same right -angle prism. The advantages are simple shapes, light transmission and brightness will have good effects, easy to process and assemble, disadvantages, disadvantagesIt is relative to the roof prism, with a large weight and volume.

Prism material:In terms of prism materials, in the current sales market, the internationally commonly adopts the brand sign of the German Shawt Company. The two common materials used in Telescope prisms are BK-7 (Shawot Company, and my country's factory approximate material brand number For K9) or BAK-4 (Schart Corporation, the similar material brand of my country's factory is K7).

BK-7 or BK-4 are both economic and efficient design that have been tested in history. In comparison, BAK-4 glass has a high refractive index, eliminating the internal light scattering loss.Essence

Nearly focal distance:That is, the distance between the observed object can be seen. For example, the near focal distance is 3 meters. Then the object is blurred within 3 meters, and the focus can be seen clearly by focusing 3 meters away.

Pupil diameter:After the light is converged by the eyepiece, the diameter formed by the spots formed after the eyepiece.For the optical equipment used by the naked eye, the light must be used to enter the retina imaging after the pupils. Human pupils are about 3mm during the day and the maximum of about 7mm at night.When observing it with optical equipment, the bright spots formed by the lighting of the eyepiece will be projected on the pupil. Therefore, the larger the diameter of the pupil, the greater the brightness of the imaging.

The calculation formula of the diameter of the pupil is: p = d / m where P represents the diameter of the pupil, D represents the diameter of the object, and M represents the magnifying multiple.

Pupil distance:It refers to the distance between the last lens of the eyes and the eyepiece when it can be seen clearly.Many binocular Telescopes are designed to grow out of the pupil Telescope, mainly because it is comfortable to use, and the viewing of the scenery is brighter, especially users wearing glasses, can not take off their glasses, and some ordinary pupil Telescopes.It is difficult to use.

Telescope Vision:Highlight the sky range that can be seen in the remote mirror or twin Tube Telescope.The field represents the maximum range that can be observed through the Telescope. Usually, it is expressed from an angle. The larger the viewing field, the larger the observation.The field of view is generally represented by the vision (observable width) and an angle of view. There are three common methods: one is to directly use angle, such as Angle of view: 9 ; the other is a thousand thousands;The visual range of the rice, such as Field of View: 158m/1000m; the third is the thousands of feet used by some countries abroad, which is actually similar to the second, such as Field of VIES: 288FT/1000Y.

Relatively brightness:The relative brightness is calculated based on the formulas such as multiple, caliber, etc. The current simple calculation method is the Square of the diameter of the pupil.

Far mirror resolution:The actual resolution of the Telescope generally does not exceed 20 ", mostly within 10", and the resolution of the naked eye is 60 ". Therefore, the naked eye that can be seen through the Telescope cannot see clear objects.

Telescope coating:Optical coating: This is the lowest -level coating. The price is cheaper. Generally, it is a mirror -surface shelter film, generally plating mirror.

Full coating: All lenses are plated with single -layer membranes.This will increase the pass rate of light from 50 % to 80 %.

Multi -layer coating: At least one film is plated more than one layer of membrane.

Full mirror multi -layer coating: This is the most advanced coating.It indicates that all mirrors are made of multi -layer coating, which can increase the pass rate of light to 90-95 %.

Wangyuan mirror eye mask:Divided into rotation and folding.

two,How to convert sports pants size

How to calculate the size of female sports pants?Many people are confused when they buy pants. Why do they sometimes wear 25 or 26, but sometimes they say what S code M code is?There are even many times that are 2 feet of waist circumference or a waist circumference of 1 feet 9. How can these be converted?And sometimes the waist circumference is performed with centimeters.How to count the size of the sports pants is a problem that confuses many people.Therefore, in this regard, it is still necessary to understand some knowledge.

For example, many people say that I wear 26 pants, so what kind of size is this 26?How to do pants size conversion?These generally have detailed explanations on the comparison tables of the store.How big is the waistline in one foot nine?In fact, one foot is equal to 33 cm, then one foot nine is actually one foot nine inches, which is a waist circumference of about 63 cm.In some shops, there are one of them, but there are actually several types. As long as you pay a little attention, you can know how to calculate the size of the sports pants.

Another is a problem with an inch, so how is the size of the sports pants when encountering an inch?It is a different name, so you can ask customer service in general.If you buy it in a physical store, ordinary salespersons can answer this question.Don't feel embarrassed, and don't think it is shameful.Only by knowing your size and knowing the sizes of pants, can you better buy your own appropriate pants.Sometimes if you buy it for others, you can also make a good judgment. You do nt need to ask a lot of things. You only need to know that one or two information can buy the right pants.

three,Size selection method

Understand my country's clothing size labeling method

According to the relevant national standards of my country, the clothing size of adult men and women is represented by a number system. In addition, we usually see such as S, M, L (usually used on leisure clothing), or 27, 27, 27. 28, 29 (usually used on pants), or 44A, 44B, 46A (usually used on the suit) and other labeling methods are irregular, but everyone is used to it. Many brands will still be outside the number system. Supplemented by everyone's habitual labeling method.

1. Adult men's and women's clothing number includes three parts: "number", "type" and "body type".Among them, "No." represents the height of the human body (represented by CM, based on 5cm as a gear); "type" indicates the net bust of the human body (on the top, generally 4cm as a gear) or a net waist circumference (lower installation, generally 4cm as a 4cm as theOne gear); "body shape" means the difference between the body's clean bust and the clean waist;

2. The classification code of the body is y, A, B, C, and Y body type is a wide shoulder and waist type (lean or muscle is specially developed), A body type is a normal body type, and the abdomen of B is slightly protruding (fat body type).The C type is obese, and the specific difference is:

male: 22-17cm 16-12cm 11-7cm 6-2cm

Female: 24-19cm 18-14cm 13-9cm 8-4cm

For example:

The 170/88A of the man is suitable for men at about 170cm (167.5 ~ 172.5cm), the net bust is about 88cm (86-90cm), and the body shape (12 to 16cm) with a normal body type (chest and waist difference).

How to simply judge whether your body shape is standard?

Generally speaking, for adult men and women, height and weight have a certain corresponding relationship.

The standard weight calculation method for Oriental people commonly used internationally:

Standard weight (male) = (height CM -100) 0.9 (kg)

Standard weight (female) = (height CM -100) 0.9 (kg) -2.5 (kg)

Normal weight: Standard weight 10%; lean: less than 10%than the standard weight; ultra -weight: greater than the standard weight 10%to 20%; mild obesity: greater than the standard weight 20%to 30%; moderate obesity: greater than standard weight: greater than standard weight30%to 50%; severe obesity: greater than the standard weight of more than 50%.
