摘　　要：细沟流流态的确定是进行细沟流水力计算时的先决条件。本文从判定细沟流流态的雷诺数和弗劳德数的原始概念设计室内试验进行数据观测。雷诺数试验结果表明 ,坡面细沟股流属于紊流范围 ,从弗劳德数的试验结果看 ,细沟股流有可能为缓流 。It is the precondition for the rill flow hydraulic calculation to confirm the rill flow pattern. This paper, based on the primary conception of both Reynolds Number and Froude Number, designed experimental and observed data. The test of the Reynolds Number shows the rill flow pattern is turbulent flow, and the test of the Froude Number shows the rill flow maybe either sub critical flow or supercritical flow.
