在过去的一个世纪内,地球温度上升了0.6摄氏度,这直接导致了地球上由风暴、洪水、干旱等引起的各种天灾成倍增加。
By theoretical calculation, it is found that the same earth temperature gradient leads to the greater difference of temperature stress in different kind of rocks.理论计算发现,相同的地温梯度在不同的岩石中引起的温度应力相差很大。
Shallow earth temperature is influenced by surface temperature change everyday and every year, topographic change, elevation change and surface feature change, so it should be corrected.浅层地温受到地表气温的日、年变化、地形变化、高程变化和地貌变化等的影响,应对实测值进行相应校正。
