1. Play basketballProtectWhat is the role

The finger protection is a piece of fabric for protecting the finger joints. It is one of the essential sports equipment for many basketball players. So what is the use of playing basketball and wearing a guardian?

For basketball, fingers are the parts of the common activity and one of the areas that are easily injured, especially professional basketball. They often collide with basketball. The damage of the opponent's finger joints is quite large.The opportunity is also very high. To protect it is not sprained or accelerated, wearing fingers are one of the effective ways.

The index finger is mainly to protect the joint of the opponent's finger. When the fingers are strongly impacted, the joints are limited to the bending amplitude, and will not change.The five fingers of the trauma occurred; and after bringing the fingers, it is not easy to slip because of sweating. In addition, many nursing fingers are now more beautiful and can also play a certain decorative role.

2. Is basketball guarding useful?

it works.

Dai Hu is very useful when playing basketball. Friends who often watch basketball games will find that many basketball players are Dai Hu's finger, mainly to protect; for those who play basketball, because sports are not in sports, there is no exercise.So fierce, the protective effect is not obvious, but the protection of the finger also helps to master the ball: the slow lens of basketball that generally seen on TV when flying in the air, the ball is rotating, the arc is high, it is beautiful and easy to enterBall, that is because most basketball players have a larger palm, and their fingers are slightly longer than ordinary people. When ordinary people play, because the palm of the hand is small, it is easier to master the finger.Khan will not slip.

Third, how to deal with the finger poke during basketball

When we played basketball, most of them pierced their fingers because of the overly intense impact.Of course, there is another situation that the nails are too long. When the nails are impacted, the fingers are very depressed and suffer.

When we play basketball, we remember to deal with nails first. Do not be too long, so it is easy to hurt others, and it is also easy to hurt ourselves.At the same time, before the basketball, we must fully prepare the fingers. If you have the conditions to slide the UA, you can wear a finger.

The fingers that occur in the basketball can be poked, and it can be divided into sprains, dislocation, fractures, tendon broken, and trauma (Skin cracking).

If a sprains occur, you need to make cold compresses first.When dislocation, we must tolerate the pain caused by dislocation, and let the medical staff pull their fingers straight to restore the original state.If your fingers are severely injured, fractures, and tendons, you must not move around, go to the Hospital immediately. This situation is not personal.

How to give rabbits for rabbits to nursing rabbits for daily nursing analysis

1. Comb hair

Tutu spends a lot of time to lick your whole body every day. It really loves clean things, but therefore also swallow a lot of hair into the stomach, once too much eats (especially in the season for changing the hair), block the intestines, and block the intestines.Causes the intestinal peristalsis and causes hair balls.

Combing cycle: Usually once a week, in the season for changing the hair, when you find that there are more hairs that have been combed than in the past, that is, the description starts, which can be increased to twice and three times a week ... or even every day.The season for adult rabbits is spring and autumn, while the young rabbits are more frequent.

2. Pruning nails

rabbit's nails grow infinitely. Bunny is Running frequently, and it is necessary to dig holes to build nests. Naturally, our pet rabbits obviously do not need to be so hard.Hard work, help them repair nails regularly.

Pruning method: Generally, two people are needed, one person holds rabbits, and the other holds its small claws with one hand.Pay special attention to trimming. The structure of the rabbit nails is the same as that of cats and Dogs. There are blood vessels in the inside. You must not cut it! Leave another white part of 1.5-2mm in front of the blood vessels, and the rest is cut off.Dark -colored rabbit nails will also be dark, so you can't see the blood vessels (you may be seen in the sunlight), then you can only cut a little at a time.

Pruning cycle: Pay attention to observation, you can determine according to the growth of rabbit nails.It should not be less once in January.

3. Check the ears regularly (or often)

It refers to the inner part of the outer ear (the inner ear can not touch, nor can it be allowed to fall in!), This part is the only thing that rabbit cannot clean up by itself.If you find that the inner part of the rabbit's outer ears is prone to dirt, you need to wipe regularly. Usually you can use cotton balls to wipe lightly with water. Note: Never let the water enter the ear canalUse alcohol cotton, hydrogen peroxide and other things for self -made.There are dandruff or hard -shell -like objects that are sick and need to see a doctor.

4. In addition to the reasonable diet for the rabbit and the above, there are actually many care for rabbits:

Pay attention to checking whether its Skin is secreted by physical secretions, pay attention to whether the hair of its feet is severe or even skiniest, and sometimes it is different from its belly. I often check whether the teeth are too long and flat.The molars are regularly disinfected with tableware and cages.

1. What time does the Fishing gear shop open the door?

2. Can the Fishing gear store rent a Fishing gear?

More and more friends choose to come out to fish with relatives and friends on weekends. While enjoying the fun of fishing, they enjoy the scenery of nature.Not only can we resolve the distress of working on weekdays, but also self -cultivation and cultivation.However, many novices are not confirming whether they will really fall in love with this activity. It seems uncomfortable to buy Fishing gear equipment directly. Many people are curious. Want to know that fishing gear shops can rent Fishing gear?

Generally speaking, it can be leased. The larger city is 50 to 60 yuan a day, and the price of small cities a day is ten dollars. Some also have bait, which is also a very convenient way.

The above is the introduction of the content of the Fishing gear shop and the content of Fishing gear for the Fishing gear store. I hope to help you. There are many related knowledge in the homepage. Welcome to click to view it.

1. How long can the Solar lawn Lights be on

Solar lawn Lights are a green energy lamps. It consists of light sources, controllers, batteries, Solar cell components and lamps. It is a type of courtyard light. It is mainly installed on the lawn.Park lawn landscaping embellishment.So how long can Solar lawn Lights be on?

Solar lawn Lights are different from traditional lawn lamps. Because they choose Solar cells as power supply and use LED light sources, their lighting time can be controlled.The lighting time of Solar lawn Lights can be set according to the needs of the user, which is related to the choice of Solar cell components and batteries. The greater the power and battery capacity of the Solar cell module, the longer the lighting time. Generally speakingIt can ensure that whether it is sunny or rainy, it can maintain a lighting time for 5-8 hours.

2. What should I do if the Solar lawn lamp is not on?

Solar lawn Lights are often used for grassland lighting. As a type of Outdoor lighting, it sometimes causes damage and is not light. So what is the reason for Solar lawn Lights?The reasons and solutions of Solar lawn Lights are not bright: as follows:

1. Damage of light source

Due to the natural or artificial reasons, the light source is damaged, causing the Solar lawn light system to be unable to work, when it is bright and not bright, flickering, etc. during maintenance or replace the light source.

2. Damage to Solar panels

When the Solar panel does not have any load, it is connected to the universal meter to test its voltage. Generally, the working voltage of the system is 12V. Under normal circumstances, it will be higher than the 12V voltage. Only the voltage is higher than 12V.Charging the battery, which causes the Solar lawn Lights to not work or work time, and the Solar panel needs to be replaced.

3. The positive and negative pole of the Solar panel

The Solar courtyard lighting system will only light up once after installation. After the battery is used, the Solar courtyard light will never be on. At this time, the Solar cell board is generally needed to change the positive and negative pole.

3. precautions for the use of Solar lawn Lights

When installing and using Solar lawn Lights, the matters that need to be noticed are:

1. Pay attention to the height of installation. Do not allow the height of the lawn to be higher than Solar lawn Lights, so as not to affect the collection of solar energy.

2. When the Solar lawn light is installed, a wire that is not less than the power distribution phase wire is used as a ground wire to connect the metal shell of the lamp or the lamp column to ensure good and reliable grounding.

3. Pay attention to the pitch in installing Solar lawn Lights, so that the lighting effect is better and ideal, it can also save costs.

[Astronomical Telescope maintenance] How to maintain the astronomical Telescope?maintenance of astronomical Telescope

The purchase of the Telescope is important, but it is as important as maintenance and maintenance.The astronomical Telescope is a precision instrument, which directly affects the use and life of the Telescope. Therefore, it is necessary to use it to use it and be custody. Non -professional should not easily disassemble and repair it.

1. maintenance of optical system

(1) Ensure that the Telescope is placed in a ventilated, dry, and clean place; all eyed mirrors, prisms, secondary imaging mirrors, and other small optical parts attachments should be placed in a dry box or dry tank with desiccant when not in use.At the same time, pay attention to replace new desiccants.Do not use Telescopes, and do not open the object mirror cover in rainy days, wind and sand, and humidity (more than 85%). Especially for reflecting Telescopes of non -sealing windows, gray sand is the biggest enemy.In the mildew season in the south, the two ends of the lens barrel can be tightly tightened with impermeable plastic Bags. The desiccant (do not touch the lens) in the inside of the bag can be placed inside, and new desiccants are often replaced to keep the dry mirror dry.

(2) If there is dust such as dust on the optical mirror surface, gently blow the ear balls and do not blow it with a mouth to avoid splash splashing on the mirror;Layers and mirrors; do not touch the optical mirror surface with your hands. The fingerprints left will often corrode the mirror surface and cause permanent traces.If you accidentally wipe your fingerprints as soon as possible, a mixed fluid droplet of 50 % of the water -free ethanol and ether should be dripped on the clean skilled gauze, and gently turn to the mirror edge from the center of the mirror or counterclockwise from the mirror center.Wipe (you can only wipe it in one direction, you can't wipe it back and forth), and constantly change the skim cotton ball until it is cleaned.In addition to the usual attention of the Telescope mirror, cleaning should be cleaned from time to time. Do not use organic solvents to the lens to avoid damaging the diaphragm. For aluminum -plated reflex mirrors, try not to wipe as much as possible to prevent aluminum membrane damage or fall off.

(3) Portable Telescope try not to observe on the foggy forests, water and seaside. If it is not necessary to observe, you should wipe it as soon as possible after the observation.

(4) The reflex mirror surface of the reflecting Telescope should be coated regularly (1 to 3 years) to ensure that the reflector surface has a good reflection rate.

The maintenance and maintenance of large and high -end Telescopes is best to ask professionals in astronomy units to assist in.

2. maintenance of the Turn instrument

(1) The mechanical and tracking system of the Telescope is a high -precision transmission system, but because its speed is slow, it generally does not need to be maintained frequently. It is just according to the requirements of the instructions.); If the model of lubricating oil (fat) is different, please clean the original lubricant (fat) with kerosene and then add new lubricant (fat). Be careful not to put different types of lubricating oil (fat)Mixed use.Conditional units or individuals, if you can use it for a few years, ask professionals to re -clean, refuel, and adjust it will be very beneficial.

(2) The control system of the Telescope should be checked from time to time. When used, it should be operated strictly in accordance with the requirements of the instructions. Usually, water droplets, water vapor, and foreign matter should be prevented from entering the circuit part. The battery should not be removed for a long time.

3. maintenance of the electronic control system

The electrical control system of the Telescope is very different due to different models and functions, but the attention points to the use of maintenance are basically the same:

(1)Check whether the input AC voltage is the same as the rated voltage of the Telescope. When using the DC power supply, you should also pay attention to whether the rated voltage of the battery pack or battery is consistent with the requirements of the Telescope electronics control.

(2)In high -power driving circuits, please pay attention to the heat dissipation tablets of high -power tubes. Do not touch each other to avoid burning the Tube.

(3)Do not pull the trail and randomly cross all the power supply or electrical control cable to avoid disconnection.
