摘　　要：根据实地测试数据提出了一种简便的入渗方程,并由此导出入渗速度与入渗时间的关系以及入渗速度的渐近稳定值.试验表明模型的拟合性能良好.还在理论上证明了在足够大的实用时间范围内,本方程与 Philip 入渗方程形式上是一致的.Being based on the field investigations,a simple infiltration equation was intro- duced,and thereby the infiltration rate function of time and the asymptotic steady infiltration rate were also deduced.The examination with several sets of field data showed that there was complete agreement between the tested and calculated data(by the use of our equation).The mathematical probe into our equation demonstrated that the two infiltration equation(ours and Philip's)were identical within the scope of time large enough to use our equation in the fields.
