Advantages and disadvantages of snow

Children often ignore the role of snow when they look at Yushu Qionghua. Snow has many benefits to human health. Compendium of Materia Medica has long recorded that snow water can detoxify and cure the plague. There is a folk prescription for treating fire burns and frostbite with snow water. Taking a bath with snow water often can not only enhance the resistance between skin and body, reduce diseases, but also promote blood circulation and enhance physical fitness. If you drink clean snow water for a long time, it will help you live longer. This is one of the "secrets" of the old people who have lived in the deep mountains and forests for a long time. Why does snow have such strange functions? Because snow water contains less heavy water than ordinary water 1/4. Heavy water will seriously inhibit the life process of living things. According to experiments, fish will die quickly in water containing 30 ~ 50% heavy water. The most basic condition for the formation of rain and snow is the existence of "condensation nuclei" in the atmosphere, and solid impurities such as dust, coal particles and minerals in the atmosphere are the most ideal condensation nuclei. If meteorological factors such as water vapor and temperature in the air reach certain conditions, water vapor will condense into snowflakes around these condensation nuclei. Therefore, snowflakes can clean a lot of pollutants in the air. So every time after the heavy snow, the air is particularly fresh. According to the measurement, the density of new snow is generally 0.05 ~ 0. 10g per cubic centimeter. Therefore, the reflectivity of ground snow to sound waves is extremely low, which can absorb a lot of sound waves and help reduce noise.

Snow has a wide range of functions, but it is of great benefit to mankind. First, it is beneficial to the growth and development of crops. Because of the poor thermal conductivity of snow, covering the soil surface with a layer of snow can reduce the heat transfer from the soil and the invasion of cold air, so that crops can get a bumper harvest in the coming year.

The role of Xuemaike 220.113.173.164 2005-1-16: 47: 28 Compendium of Materia Medica There is a folk prescription for treating fire burns and frostbite with snow water. According to experiments, fish will die quickly in water containing 30 ~ 50% heavy water. The most basic condition for the formation of rain and snow is the existence of "condensation nuclei" in the atmosphere, and solid impurities such as dust, coal particles and minerals in the atmosphere are the most ideal condensation nuclei.

Therefore, snowflakes can clean a lot of pollutants in the air. So every time after the heavy snow, the air is particularly fresh. According to the measurement, the density of new snow is generally 0.05 ~ 0. 10g per cubic centimeter. Therefore, the reflectivity of ground snow to sound waves is extremely low, which can absorb a lot of sound waves and help reduce noise. Taking a bath with snow water often can not only enhance the resistance between skin and body, reduce diseases, but also promote blood circulation and enhance physical fitness. If you drink clean snow water for a long time, it will help you live longer. This is one of the "secrets" of the old people who have lived in the deep mountains and forests for a long time. Why does snow have such strange functions? Because snow water contains less heavy water than ordinary water 1/4. Heavy water will seriously inhibit the life process of living things. Just like a wonderful carpet, it covers the earth, so that the ground temperature will not drop too low because of the cold in winter. This heat preservation effect of snow is inseparable from its own characteristics. As we all know, it is warm to wear a cotton-padded jacket in winter. Why is it warm to wear a cotton-padded jacket? This is because the porosity of cotton is very high, and the pores of cotton are filled with a lot of air, which has poor thermal conductivity. This layer of air prevents the heat of human body from spreading outward. The snow covering the breast of the earth is very similar to cotton, and the porosity between snowflakes is very high. It is this layer of air that drills into the pores of the snow to protect the ground temperature from falling very low. Of course, the thermal insulation function of snow changes with the density at any time. It's like wearing a new cotton-padded jacket, which is especially warm, and the old cotton-padded jacket is not very warm. The density of fresh snow is low, and there is a lot of air stored in it, so the heat preservation effect is particularly strong. Chen Xue is like an old cotton-padded jacket, with high density and weak heat preservation effect, because there is less air stored in it. Why does the more air an object stores, the stronger the heat preservation effect? This is because air is a bad conductor. As we know, any object itself can transfer heat, and this property of transferring heat is called the thermal conductivity of the object. Among several common substances in nature, air has the worst thermal conductivity. Therefore, the more air an object contains, the worse its thermal conductivity. Because the amount of air that can be contained in snow changes greatly, the thermal conductivity of snow also changes greatly. Generally, the newly fallen snow has large pores and the best heat preservation effect. In the late stage of snow melting in spring, snow is soaked by water, and its thermal conductivity is closer to that of water.

Heavy snow in winter can freeze some overwintering pests to death; Snow water goes deep into the soil layer, which can provide the needs of crop growth; Frequent bathing with snow water can enhance the resistance between skin and body, reduce diseases, promote blood circulation and enhance physical fitness.
