蒸发的测定或计算是气象学的古老问题之一,曾经提出过各种方法,如蒸发器法、经验公式法、梯度观测法、热量平衡法、水分平衡法等等。但以往这些方法不区别影响蒸发过程的普遍原因和特殊原因,因此不能把各种不同下垫面的蒸发问题联系起来研究,有一定的局限性,准确性也还不高。本文试图以“矛盾的特殊性和普遍性及其互相
Determination or calculation of evaporation is one of the ancient problems of meteorology. Various methods have been proposed, such as evaporator method, empirical formula method, gradient observation method, caloric balance method and water balance method. However, in the past, these methods did not distinguish between the common causes and special causes that affect the evaporation process. Therefore, it is impossible to study the evaporation problems of various underlying surfaces and has some limitations and the accuracy is not high. This article attempts to ”the particularity and universality of contradictions and their mutual
