摘　　要：选用河南省1951～1980年地面气候资料,探讨和检验了几种应用常规地面气候资料计算河南省多年平均水面和陆面蒸发量的方法,对计算结果与水资源评估所得结果进行了分析比较,并对所采用方法的可靠程度进行了评定,其结果对黄河流域水资源调查评价有参考价值.Based on the tests in laboratory on the concrete composed of manufactured sand and fly ash, the relationships of the strength of concrete and the binder to water ratio are analyzed by the method of liner regression and the coefficient values of aa and ab are determined respectively. These formulas are demonstrated by engineering data.
