摘　　要：应用流体力学和非牛顿流体力学理论，从最基本的连续性方程和动量方程入手，导出了控制幕律体浑水轴对称层流自由射流的偏微分方程组和常微分方程，得出了常微分方程的数值解，并把其数值解的结果与清水射流数值解的结果进行了对比，指出塑性指数ｍ≠１时其射流流量与初始动量有关，且无因次速度分布ｕ／ｕｍ是ｍ和ｒ／ｒ０的函数。Based on fluid mechanics and non-Newtonian fluid mechanics,the paper derived partialdifferential equations and ordinary differential equation guiding free axisymmetric submerged jet ofpower-law muddy water and got the numerical solution,The paper points out that the volume flow rateof muddy water jet depends on the initial jet momentum and that the nondimentional velocity distribu-tion of muddy water jet is some kind function of both m and u/um
