摘要

为了处理在野外测试中得到的地表径流和土壤渗透资料

采用了曲线拟合方法。通过处理

建立了降雨时间与地表径流系数、渗透时间与土壤渗透量、渗透时间与渗透速度关系方程

在比较两组方程中

选取了具有较佳拟合效果的一组方程作为在实际应用中的数学模型。

Abstract

In order to process data of direct runoff and water infiltration through soil from field tesrs

curve-fitting techniques were used. By progressin gestablished equations express mutual relations between rainning time and funoff coefficient

between the time and infiltration capacity

between the time and infiltration velocity

respectively. Selected one from two groups of equations achieve optimum fitting effect and was used as mathematical model in practice.
