温室效应的影响,幸免的办法(国外英文资料).doc

温室效应的影响,防止的措施(国外英文资料) The greenhouse effect refers to the warming and warming effect of transparent covering to protect microclimate. The principle of warming up is: (1) a small amount of solar radiation income is reduced, but a large amount of longwave radiation energy expenditure that blocks the upward distribution of the earths radiation, so that the radiation budget of the protected areas tends to be more income than expenditure. The cover can block the ground upward (daytime) of the turbulent heat input, the protection of temperature increasing. Atmospheric greenhouse effect refers to the warming effect of atmospheric substances on the near zone, the principle and the principle of temperature increase with the increase of CO2 4 is similar to that in the atmosphere warming material, the long wave radiation energy expenditure can be more ground and the barrier layer near the air into space, from which the earths climate warming. Its positive role is the part of arid area may increase in rainfall, high latitude agricultural area heat changes, but more important is the negative effect, it is of tropical and temperate drought and flood disasters occurred frequently, and the tip of melting, sea level rise, coastal Delta submerged. Therefore, the reduction of atmospheric gain? The emission of materials is an urgent task for mankind. There are two characteristics of a greenhouse: the temperature is higher than the outside, and the heat does not dissipate. In life, we can see the glass with greenhouse and vegetable greenhouses is a typical greenhouse. The use of glass or transparent plastic film to do is let the sun light greenhouse, can direct sunlight into the greenhouse, heating indoor air, and glass or transparent plastic film can also keep the indoor air heat radiates outward so that the indoor temperature is kept higher than the outside of the state, to provide favorable conditions for the rapid growth of the plants. The greenhouse effect caused by environmental
