大气降水入渗补给潜水存在着滞后效应。入修补给潜水的过程是一个正偏态曲线，可用瑞利分布来描述，把大气降水入渗补给量合理地分配到各计算时段中去。本文通过实例讨论了降雨补给潜水的滞后分配问题；以端利分布为核函数来描述降水入渗补给潜水的过程时，所需的分布参数（尺度参数β和随机变量x）可用滞后时间长度Ts与入渗时间长度Ti来求得，而Ti、Ts可按野外长现资料确定出。
Atmospheric precipitation infiltration recharge diving there is a lag effect. Into the repair process to the diving is a positive skewed curve, Rayleigh distribution can be used to describe the amount of recharge recharge the atmosphere to a reasonable allocation of time to go to the calculation. In this paper, we discuss the problem of lag distribution for rainfall recharge submersibles. The distribution parameters (the scale parameter β and the random variable x) required to describe the process of precipitation infiltration recharging diving using the end-loss distribution as a kernel function can be described by the lag time Ts And infiltration time length Ti to obtain, and Ti, Ts can be based on field data to determine long out.
