[Shading Ball] What is the environmentally friendly and creative black plastic ball in the Shading ball

The diameter of the shade ball is about 10 cm, covering the 71 hectares of the reservoir, which can be isolated from the dust, rain, birds, and wild animals. It can also reduce the photosynthesis of algae, reduce the production of carcinogens, improve the quality of drinking water. Every yearIt can also reduce the water of 300 million gallons (about 1.135 million public ascension).This is equivalent to the water volume of 454 Olympic swimming pools, which is enough to supply 8,100 people for a year.

There is no significant signs of disasters in California's California. Los Angeles is ingenious and protects urban water sources in a different way.The official has recently invested 96 million floating sunshade to the 75 -acre Los Angeles Reservoir in Hillma, California.They hope to use these black plastic balls to protect the water from drought, rain, chemicals and wild animals, and prevent 300 million gallon of water from evaporating from here each year.

These balls float on the water to block the sun.In addition to preventing the evaporation of water sources, they can also prevent chemical reactions that cause carcinoma bromate.Cromine is a chemical composition produced by bromide naturally formed in water.For the vast majority of people, it is unlikely that ingesting of bromate is unlikely to cause problems.However, people who eat a lot of bromate will have symptoms such as nausea, vomiting, diarrhea, and abdominal pain.These black balls are made of polyethylene, each with 36 cents.They are black because only this color can turn ultraviolet rays.Dr. White, a former biologist at the Los Angeles Hydropower Bureau, was the first person to protect the water quality with a Shading ball.When he heard that the bird ball was used along the pool along the airport runway, he germinated the idea.

1. Do you have to wear a helmet on a bicycle?

The answer is yes, you must wear a helmet when riding a bicycle.This is not only responsible for your own life security, but also responsible for the safety of others.Let's explain in detail why you need to wear a helmet for a bicycle.

First of all, the helmet is the first line of defense of the bicycle cyclist.During the cycling process, if an accident occurs, the helmet can effectively protect the head and reduce the risk of head injury.According to research, head injuries are one of the main causes of the death of a bicycle accident.The helmet can absorb the impact and reduce the damage of the impact force on the head, thereby greatly reducing the risk of death and serious injuries.

Secondly, the helmet can reduce the occurrence of cerebral vibration.Brain vibration is a common trauma of brain, which may lead to long -term health problems and even affect the quality of life.The helmet can effectively protect the head and reduce the occurrence of brain vibration.

Furthermore, the helmet can also prevent faces and eyes from being injured.In a bicycle accident, faces and eyes are the most vulnerable parts.The Bicycle helmet can cover these parts to prevent them from being hit directly.

However, although the importance of a helmet is self -evident, in actual life, many people do not develop the habit of riding a bicycle and wearing helmets.Some people think that the speed of bicycles is slow, and there will be no big things; some people feel that the helmet is uncomfortable and unwilling to wear it; others are because they are troublesome or worried that the helmet will stain their hair and don't want to wear it.

These concepts are wrong.Although the bicycle is slow, once an accident occurs, due to the effect of human inertia, the power of falling is very large, which can easily cause serious damage.Moreover, the comfort of the helmet can be improved by selecting the appropriate model and adjusting the method of wearing.As for worrying that the helmet will soil the hair, you can choose a helmet that is breathable and easy to clean.

In addition, we need to know that the choice and use of helmets are also a science.First of all, the size of the helmet should be appropriate, not too large or too small; second, the buckle band of the helmet must be firmly fixed on the head; in the end, the validity period of the helmet is generally 3-5 years. After the expiration, a new helmet needs to be replaced.Essence

2. Can't check the helmet for a bicycle

At present, there is no clear traffic regulations in my country that riding a bicycle must wear helmets.However, this does not mean that wearing a helmet when riding a bicycle is not important.

In fact, the public security traffic police department has always suggested to wear helmets while riding a bicycle.Although most cities are forced to wear helmets for people riding electric cars, riding bicycles also have certain risks.When an accident occurs, the helmet can effectively protect the head from serious damage.

In recent years, in order to improve the safety awareness of citizens and ensure the safety of the people, the Ministry of Public security has increased its efforts in terms of traffic management.Especially for people who ride motorcycles and electric bicycles, they strictly check whether they wear safe helmets that meet standards.

Although cycling has not been forced to wear helmets, it is still necessary for those who have long bicycles or often travel to bicycles.Because once a traffic accident occurs, the head is often one of the parts that are most likely to be severely damaged.

In short, although there is no compulsory request for traffic regulations to ride a bicycle to wear helmets, for their own safety reasons, it is recommended that the majority of citizens wear helmets while riding a bicycle.

What are the self -rescue measures in the mountain climbing

1. Use the direction of nature to distinguish between nature

It is not terrible to be trapped by getting trapped. The key is how to find ways to go out after getting lost. It is very helpful to save some common knowledge about the common sense of survival in the wild.

Use the compass (north needle) to distinguish.A high -quality compass is a must -have for wild tourism, but the compass pointers point to"North" or " N "This direction is the direction of magnetic north, and there is a deviation angle with the direction of Zhenbei. The number of magnetic bias angles should be calculated to obtain an accurate direction.

The watch with a pointer is used to flatten the watch, the dial up, rotate the watch, and point the clockwise of the watch box to the sun.At this time, the timing of the table and the dial on the dial12 Points to form a angle, the direction of the extension of the angle flat line of this angle level is the south.

It also depends on the direction of nature.The Arctic Star is the best northern needle. The direction of the Arctic Star is the direction of the north.Beidou Qixing is also a big bear constellation, like a huge spoon, which is easy to find in the clear night sky. From the direction of the extension of the two stars on the spoon, about it.5 Double, there is a brighter star is the Arctic Star, that is, the north.

Judge the direction of plant growth.Trees, moss The lush crown should be the south, and the sparse side is the north.

In addition, the direction of the trees can be determined by observing the annual wheel of the trees.The sparse side of the annual wheel pattern faces south, and the dense side of the line faces north.

Second, the signal of distress first

Now basically everyone wears mobile phone and other communication equipment. If it is trapped on the mountain, the first way of asking for help is naturally using a mobile phone to call the police or contact relatives and friends.

However, there may be a bad phone signal on the mountain, or the mobile phone is out of power, so you need to master other ways to ask for help.

If you carry your whistle with you, please keep a whistle to attract the attention of others. The mountains are generally quieter and the sound can be passed far. If there is no whistle, it is also possible to call for help.But call for help should not be too frequent to prevent too much physical strength.

In the evening, fire is the most effective signaling method.Three piles of fires make it a triangle (international universal trapped signal), or line into a straight line.As long as time and situation permission, the fire will be piled up as soon as possible, and be careful not to extinguish them.

You can use branches, bright cloth strips, or other objects that are easier to see by the naked eye.SOS Or for help signals, if there are planes flying across the mountain, it will be easier to see.

In addition, if the wild adventure is lost during the day, you can use the mirror to use the sun to reflect the interrupted light signal to the rescue aircraft in the residential area or in the air, or you can place your clothes on the ground or on the top of the tree.The pattern sends a signal.

3. Find a good shelter

When being trapped in the wild, isolated and helpless, we cannot get out of danger in a short time, or someone is injured, and it is inconvenient to move. We can only spend the night in the wild and find a way to build a temporary wild in the wild.Shelter.

According to the local geographical conditions, using the grace of nature, sometimes it can be found that the ready -to -be natural asylum can be temporarily settled, such as caves, tree holes, and trees of tree.

If you can't find other shelters, some concave pit can be used.Cover some branches and weeds on the pit, and put some dried grass at the bottom of the pit to sleep.

This transformed asylum is like a shallow kiln. It is better to keep warm and wind -like effects than tents, especially in cold areas. Such asylum can even live for a long time.

If you can't find a ready -made or semi -categorian asylum, you can only build it.There is no limit to the materials for the establishment of asylum. According to the local situation, there can be a lot of options. As long as you have more brains and try more, a comfortable and strong shelter is not difficult to build.
