Stratosphere stratosphere (stratosphere), also known as the stratosphere. Definition 1: From the top of the troposphere to about 50 km altitude in the atmosphere. Inner layer temperature usually increases with increasing height. Bottom temperature changes little with height. Applied science: Atmospheric Science (a subject); Atmosphere (two subjects). Definition 2: Jude Biao's atmosphere about 10 to 50 kilometers. Located below the top of the troposphere dichloromethane, fugitive layers. Applied science: Ecology (a subject); Global ecology (two subjects); stratosphere (stratosphere), also known as the stratosphere, the Earth's atmosphere on a hot cold dichloromethane layer uses, this layer is divided into different temperature layers, layer them on top of a high temperature, while cold layer is disposed on the lower part. It is located close to the surface of the lower troposphere is just the opposite, lower troposphere is the cold heat. In the mid-latitudes, stratospheric located 10 to 50 kilometers away from the surface height, while in polar methylene chloride manufacturers, this layer is 8 km away from the surface begins to extract polyphenols in tea, Anhui, Yunnan, Sichuan, Hubei and other provinces rich tea can be broken at the end of mass times the production of tea leaves or tea polyphenols and caffeine times. Polyphenols are a very good antioxidant, widely used in food and cosmetics, etc., have been found to have anti-caries bactericidal effect of tea polyphenols, tea polyphenols in medicine can lower cholesterol, lower blood pressure, blood fat, anti-aging effect and is therefore an excellent natural food additives. Chemically extracted polyphenols compare with CO? Supercritical extraction of polyphenols produce pure, so in a lot of tea cultivation areas of this project, there must be greater economic benefits. Besides caffeine is also commonly used drugs Shandong dichloromethane, which would previously thought useless defective, into high value-added products. 100 tons of tea polyphenols end can extract 5 tons, the output value of nearly a million.
