摘    要:为提高潜水蒸发计算精度,利用潜水蒸发强度、埋深为零时的土面蒸发强度和水面蒸发强度的实测资料对阿维里扬诺夫公式、叶水庭公式和雷志栋公式中E0值的选取进行了探讨,同时对比分析了E0分别为水面蒸发强度和埋深为零时土面蒸发强度两种情况下的潜水蒸发强度。结果表明,针对新疆地区粘壤土类型,对于上述三种公式,若用埋深为零的土面蒸发强度代替水面蒸发强度,计算结果会产生误差,精度偏低,应选用E0为水面蒸发强度进行计算,获得了η与地下水埋深的指数函数关系。该研究为潜水蒸发经验模型中E0值的选取提供参考,同时为求解雷志栋公式中参数η提供一种新方法。

关 键 词:潜水蒸发  经验模型  水面蒸发  土面蒸发

Abstract:literature research on the concept of sports and leisure consumption point defined on the basis of investigation of 600 college students in Guangdong Province, some colleges and universities, sports and leisure consumption characteristics. The results show that Guangdong college students in sports and leisure consumption at a high level, boys and girls there is no significant difference in the spending limits and pointing. The current consumption occurs mainly in the consumption of material consumption and activity. The main motivation is college sports consumer interest in sports and leisure activities, while its consumption constraints that poor economic capacity.
Keywords:groundwater evaporation  empirical model  evaporation of water surface  evaporation of soil surface
