Fifth, how to choose Luya pole tone and hardness

1. The tone of Luya pole

Children's pole is suitable for handling hard bait, fast -tone road Asian pole is suitable for manipulating soft bait.Because the sensitivity (conduction) of the pole is different, the faster the tone, the better, and the more obvious the bite of the fish is perceived, so we often choose the tone of the fast -tuning above -F or XF.And the throwing the medium -to -MF (MF) pole is better than the fast -tone pole. The comprehensive performance of the medium fast adjustment is strong. In order to solve the problem of throwing, beginners often choose medium fast poles.In the middle, the below -M, S, SS, the sticky fish is better, it is not easy to run fish, and at the same time, it can filter the vibration of the hard bait itself, thereby enlarging the fish news.

2. The hardness of Luya pole

The soft rod is suitable for throwing small bait fishing fish.When throwing, we will use the elasticity of the pole tip, because the soft rod elasticity is good, the bait range is small, the bait is more comfortable, the big bait pole is easy to break, and it is not far away.The elasticity of the pole tip of the hard pole is not enough to drive the small bait. One is uncomfortable, and the second is not far away, so the hard pole is suitable for throwing big bait.

We can choose the Luya pole of different hardness and tone according to different fishing grounds and target fish.For example, the Leiqiang fishing method in the heavy grass area, we can choose the median hard pole; and the use of soft bait fishing catfish, in order to perceive the slight motion of the water, can choose the soft fast rod.

[Elbers' effects] What are the elbows how to wear elbows and elbows how to use elbows

1. The function of elbows

The role of elbows is to provide stress to reduce swelling; the second is to restrict activities so that the injured parts can be restored.At the same time, it is best to try not to hinder the normal operation function of the hand, so if it is not necessary, most elbows are not restrained.

Elbers and knee pads are designed to prevent the elbow and knees from being injured and wearing cushions or hard shells.In order to reduce the weight of the equipment, the designer briefly, beautiful, convenient, and practical the elbow and knee pad design.

Friends who like to play tennis, Badminton, and table tennis play in a ball, especially when playing against the handball, the elbow will hurt, even if we wear elbows, the expert will tell us this commonly known as "tennis elbow"EssenceAnd this tennis elbow is mainly at the moment of hitting the ball. The wrist joints are not braking, the wrist is not locked, and the extensor of the forearm is excessively pulled, causing damage at the attached point. After the elbow joint is protected, the wrist joint is not protected.There is still an excessive excessive flexion when hitting the ball, so that the damage to the elbow joint can be worse.

So when playing tennis, if you feel the elbow pain, you'd better wear the Wrist care while wearing the elbow.And when you choose the elbow, you must choose no elasticity. If the elasticity is too good, it will not be a protective effect.And don't be too loose when you wear it too tight, too tight will affect blood circulation, too pine can not play a protective effect.

In addition to these three big goals and three small balls, young friends like some extreme sports, and they must wear professional Sports guards to effectively prevent being injured.In the end, it is reminded that the protective gear only plays a certain protective role in exercise, so in addition to wearing some protective gear during the sports competition, everyone should try to master regular technical motion and strictly abide by the rules of the competition.In addition, once you are injured in the exercise competition, you must first stop continuing exercise. If you have the conditions, use ice cubes to apply ice to relieve pain, and then you must go to the Hospital to find a professional doctor for pressure bandaging.

2. basketball elbow protection

Everyone thinks that gloves and elbow -nursing are designed to protect hands and elbows. In order to meet this need as much as possible, the producer produces a variety of elbow protection. There are many types and styles of elbows.When the ball player is training or game for a long time, when he feels that the ball is very difficult to grasp, he often hopes to use elbows to increase the power of the hand.

basketball has become a fashion movement, followed by the spread of various popular elements on the basketball court.From the once -tight jersey to the ever -changing protective gear on players, the NBA players are leading the fashion trend of the basketball industry.

If it is a fan of the god of basketball Jordan, I believe I have absolutely wearing elbows and playing.At that time, the elbows on Jordan's left arm became a unified equipment for basketball fans.Wearing the elbows as if the whole person becomes confident, and every action will deliberately imitate Jordan.However, it has been rarely seen in the event of the elbow to play. The equipment for replacing the elbow protection is to protect the arm protective with a larger area.

Elbow Putting Map

1. Positioning principle of Beidou system

The 35 satellites run around the earth at a height of more than 20,000 kilometers from the ground, surrounding the earth with a fixed cycle, so that at any time, any more than 4 satellites can be observed at any point on the ground.

Because the position of the satellite is accurate, in the observation of satellites, we can get the distance from the satellite to the receiver. Using the distance formula in the three -dimensional coordinates, the three satellites can be used to form three equations to solve the observation point of the observation point.Location (x, y, z).Considering the error between the clock of the satellite and the receiver clock, there are actually 4 unknown, the difference between X, Y, Z, and clocks, so the 4th satellite needs to be introduced to form 4 squares for solving, so as to obtain the observation point of the observation pointLavels and heights.

In fact, the receiver can often lock more than 4 satellites. At this time, the receiver can be distributed into several groups according to the satellite constellation, and each group is 4, and then the group with the smallest error is selected by the algorithm for positioning, thereby positioning, so asImprove accuracy.

The concept of "arrival time difference" (delay) is implemented: the accurate position of each satellite and the navigation information generated by the continuously sent atomic clock generated on the star of the star to obtain the time difference from the satellite to the receiver.

The satellite sends a radio signal with time and location information in the air for receiving the receiver.Due to the distance factor of the transmission, the time when the receiving machine receives the signal is delayed than the moment when the signal sends the signal, it is usually called a delay. Therefore, the distance can be determined by the delay.The satellite and receiving machine generate the same pseudo -random code at the same time. Once the two yards achieve time synchronization, the receiver can determine the delay; take the delay on the speed of light, and get the distance.

The computer and navigation information generators on each satellite understand their orbit position and system time very accurately, while the global monitoring station network maintains the position and system time of the satellite continuously tracking the satellite.Together with the main control station on the ground, with its operation control section, at least once a day, it is injected into the correction data of each satellite.Injecting data include: determination of the orbit position of each satellite in the constellation and the correction of the star clock.These correction data are calculated on the basis of complex models and can be maintained within a few weeks.

Satellite navigation system time is maintained by the pupae of the atomic clock on each satellite.Within a few seconds of NATO of these star clocks to the world coordination (UTC), UTC is maintained by the "main clock" of the US Navy's viewing table. The stability of each main clock is several 10^-13 seconds.The satellites used two frequency bands and two frequency bands in the early days. Later, it gradually changed to more frequent bands.Generally, within any designated time, only one frequency sign is working on each satellite.

Satellite navigation principle: The distance between satellite and users is based on the difference between the launch time of satellite signals and the time to reach the receiver, called pseudo -distance.In order to calculate the user's three -dimensional position and the bell deviation of the receiver, the pseudo -distance measurement requires that at least the signals from 4 satellites are received.

Due to the errors of satellite Running track and satellite clock, the effects of atmosphere on the signal on the flow layer and ionization layer on the signal, so that the positioning accuracy of civilian use is only tens of meters.In order to improve the positioning accuracy, the differential positioning technology (such as DGPS, DGNSS) is generally adopted, and the ground ground reference station (differential platform) is established for satellite observation., And released to the outside world.After receiving the correction number, the receiver compares it with its own observation value, eliminates most of the errors, and obtains a more accurate position.Experiments show that the positioning of differential positioning technology can be improved to the rice level.

Can sunscreen clothes really sunscreen?

Sun protection jackets can play a certain role in sunscreen, but cannot be fully sunscreen.After special treatment, sunscreen clothes can indeed play a role in sunscreen. However, due to the environmental impact and our cleaning, its sunscreen effect will also be greatly discounted.The fiber composition, texture and denseness of textile fabrics, and the depth of color, etc., will have a certain impact on UV resistance.Generally speaking, the anti -ultraviolet performance of the same clothing is better than light -colored, the fabric is thinner than thin, and the fabric structure is tight than loose.

The principle of Outdoor sunscreen clothes is to add sunscreen auxiliary to the fabric. There are also some sunscreen fabrics that use ceramic microfillings and fiber to increase the reflection and scattering effects of ultraviolet rays to prevent ultraviolet rays from damaging human Skin through fabrics.Its role is the same as the Parasol, which makes the Skin from being darkened from the sun, so sunscreen has a certain sunscreen effect, but it is not completely useful. It still needs to be used with products such as sunscreen.

Which sunscreen is better effect

1. Look at the label

Pay attention to the UPF and UVA indicators on the label. When buying sunscreen, pay more attention to the labels on the sunscreen jacket. See if the UPA is greater than 40 and whether the UVA is less than 5%.

2. Look at the color

The darker the color, the better the Sun protection effect.When choosing a sunscreen, try to choose darker the color. The deeper the color, the better it absorbs the ultraviolet rays in the sun, so try not to choose a sunscreen that is too light -colored for the beauty.

3. Look at fabric density

The greater the density of the fabric, the better the Sun protection effect.The density of the fabric of the sunscreen is also understood as its thickness.When choosing a sunscreen, consumers may feel that the strong sunscreen jackets will be stuffy, but research shows that the thick -proof effect of the thick sunscreen jacket is better, so when choosing a sunscreen, you should try to choose thickness as much as possible.Some.

4. Look at the fabric

Polyester fiber fabrics have good sunscreen effects.In addition to the polyester fiber on the market, there are also cotton and silk.However, after experiments, the sunscreen effects of cotton and silk did not have a strong defense effect on ultraviolet rays of polyester fiber fabrics.Therefore, when buying sunscreen, the fabric is recommended to choose a polyester fiber.
