温室效应是由于大气层中某些气体如二氧化碳、甲烷、二氧化氮等吸收热量,并把所吸收的部分热量再辐射回去而形成的。其中,甲烷可吸收的热量相当于二氧化碳可吸收热量的21倍;二氧化氮可吸收的热量约为二氧化碳可吸收热量的270倍。由于这些气体具
The greenhouse effect is due to some gases in the atmosphere, such as carbon dioxide, methane, nitrogen dioxide and other heat absorption, and the absorption of some of the heat and then back to radiation formed. Among them, methane can absorb heat equal to 21 times the heat absorbed by carbon dioxide; nitrogen dioxide can absorb about 270 times the heat of carbon dioxide can absorb heat. Because of these gases with
