摘　　要：用层流边界层方程,导出幂律流体轴对称层流自由射流的常微分方程,并给出其方程的数值解。结果表明,其射流半径与x^(1/(2n-1))成正比。且其流量与J^((3-3n)/(2-4n))成正比,说明n≠1时,流量和射流动量J是有关系的。The ordinary differential equation of round laminar jet of power-law fluid is derived, and the solution of this equation by numerical integration is obtained. The results show that the radius of jet is in proportion to x^(1/(2n-1)), and the rate of flow is proportional to J^((3-3n)/(2-4n)), Which indicat that when n is not equal to 1. there is a kind of relation between the rate of flow and the momentum flows of the jet J.
