分析表明,承压含水层中地下水水头波幅是上、下弱透水层贮水率和越流系数的减函数,是淤泥层相对透水系数的增函数;
The amplitude of the head fluctuation decreases with the storativity and leakage of both semi-permeable layers and increases with the leakance of the silt-layer.
试验在人工控制条件下,测定了“土壤水库”贮水的生产能力,冬小麦的田间耗水量与耗水系数。
This test under artificial control is used to determine the productive capacity of water stored by "soil reservoir" and the field water consumption and its consumption coefficient of winter wheat.
