水面蒸发系数全国通用公式的验证

Calculation and Verification of an Universal Water Surface Evaporation Coefficient Formula

着重介绍我国水面蒸发－散热系数研究的一项成果─—水面蒸发系数公式的计算结果与实际情况的对比，证明公式的可靠性和在全国范围内的可用性。

On the basis of numerous experimental data and practical experiences obtained from extensive evaporation Investigation of different types of water regions in China,a formula of evaporation coefficient which could be universally used in China is developed and recommended.The formula,simple in form,not only reflects closely the real picture of the mass transfer at air-water interface,but takes care of the mechanism of free and forced convection in a single expression both in form and function.The new formula has been satisfactorily compared with some well-known relevant formulas and evaporation data measured directly from various water bodies.
