摘要
本文阐述了腾发（ＥＴ）与蒸发（Ｅ）的基本概念，用水均衡原理推导了ＥＴ、Ｅ的计算公式，还根据土壤水动力学原理，推导了某些在野外难以测定的均衡要素的计算公式，并根据作者在田间的试验资料用所推公式进行了计算，结果表明该方法简单实用。
The basic concepts of evapotranspiration and evaporation are described in this paper.The calculating formulas of ET,E are developed by means of water balance equation.With the help of the principle of soil water dynaics,some formulas of water balance factors to be difficultly measured in field are derived.Finally,according to the writer's measured data in field,ET,E are calculated Using the formulas.The results show that the formulas are simple,Useful and reliable to determine in field.
