摘要
将汇流曲线的概念引入到线性时不变汇流系统,给出了汇流曲线的定义及汇流曲线之间的相互关系,这些关系适用于线性时不变汇流系统。诠释了汇流曲线的因次问题,过去认为基本单位线(通常称为时段单位线)无因次是不妥的,它应该具有流量的因次,即m3/s。利用基本单位线也可进行地面净雨的汇流计算。
The conception of concentration curve is introduced into linear time-invariant concentration system. The definition and interrelation of concentration curve are given and the interrelation fits for linear time-invariant concentration system. In the meantime, dimension of concentration curve are explained. That basic unit-hydrograph (interval unit-hy- drograph in the past) is considered as non-dimension is not suitable. However, basic unit-hydrograph should have dis- charge dimension, namely, m^3/s. The basic unit-hydrograph can be used to calculate the concentration of surface net rainfall.
