一、标题:梯形渠道的临界流(含矩形及三角形)梯形断面为人工渠槽的常用形式.临界流是明渠流中的限界流态,在水利工程中有很多应用.二、适用范围:有三种阻力指数可供选用:曼宁指数,巴夫洛甫斯基指数,佛赫哈默指数.这三种指数见“水工设计手册第一卷”7—400页,在计算临界坡降时需先明确用那一种指数.

First, the title: Trapezoidal channels of the critical flow (including rectangular and triangular) trapezoidal cross-section for the artificial channel of the common form of critical flow is the open channel flow in the limit flow in water conservancy projects have many applications. Second, the scope of application: There are three The resistance indices are available: the Manning Index, the Pavlovsky Index, the Fork-Hammer Index. These three indices are found in pages 7-400 of Volume One of the Handbook of Hydraulic Design, First clear that kind of index.
