《水文地质工程地质科技情报》(1973年,第4期)刊登了“计算渗入系数新经验公式及其应用”一文,文中分析了水均衡方程:h=z+αx,其中h=x—y,x为年降水量,y为年地表水流出量;z为年蒸发量,α为渗入系数。根据x、h三年观测资料求出x、h呈直线相关,认为直线方程斜率为渗 The article “New empirical formula to calculate infiltration coefficient and its application” published in “Hydrogeological Engineering Geological Science and Technology Information” (1973, No.4) analyzed the water equilibria equation: h = z + αx, where h = x-y , x is the annual precipitation, y is the annual surface water outflow; z is the annual evaporation, α is the infiltration coefficient. According to x, h three years of observation data obtained x, h was linearly correlated, that the slope of the straight line equation seepage
