摘要
采用Ａ．Ｒｉｔｚ方法和Ｆｏｕｒｉｅｒ级数求得梯形断面明槽中恒定均匀层流流速分布的精确解，又根据笔者建议的关于脉动粘性系数νＴ的假设，给出了相应的紊流流速分布的公式．
In this paper,the method of Ritz,A is used to obtain the exact solution of velocity distribution of steady uniform laminar flow in open channel with trapezoid cross section.Further,tased upon the author's hypothesis about eddy viscosity,the velocity distribution of corresponding turbulent flow is proposed.
