书摘太阳辐射以光波的形式进入大气层并为地球带来热能。其中的一些辐射被吸收使地球变暖,另一些则以红外线的形式反射回太空。在通常情况下,一部分向外侧发散的红外线辐射自然被大气层挡住,留在大气层里面。这是一件好事,因为它使地球上的温度始终保持在舒适的范围内。金星上的温室气体如此之厚,以至于它的表面温度高得 Book Abstract Solar radiation enters the atmosphere in the form of light waves and brings heat to the earth. Some of these are absorbed to warm the Earth while others are reflected back into space in the form of infrared light. Under normal circumstances, part of the infrared radiation diverging to the outside naturally blocked by the atmosphere, to stay inside the atmosphere. This is a good thing because it keeps the temperature of the earth always within comfortable limits. The greenhouse gas on Venus is so thick that its surface temperature is high
