本文给出了非棱柱体明渠恒定非均匀渐变流水深沿流程变化的微分方程的显式形式,进而采用四阶龙格一库塔法及其 FORTRAN 程序求得了微值解。
In this paper, we give the explicit form of the differential equation of the non-prismatic open channel constant inhomogeneous gradient flow along the flow, and then use the fourth-order Runge-Kutta method and its FORTRAN program to obtain the micro-value solution.
