摘　　要：应用层流边界层方程,导出幂律流体二维层流自由射流的常微分方程,对该微分方程求数值解。结果表明,在相同的x处,n>1的流体的最大射流速度较n=1时增加,而射流宽度减小,n<1时则相反;并且,n值偏离1愈远,这种增加或减小愈甚。计算表明,射流宽度与x^(2/3n)成正比。Derives the ordinary differential equation of two dimensional laminar jet of power-law fluid, The results of numerical integration of this equation shows that, if the power of fluid n>1, then at the same x section maximum velocity of jet is greater than that of the fluid with the power n=1, but the width of jet decreases. It is contrary when n<1, the more the n deviates from 1, the more this increasement or decreasement is. Calculation shows that the width of jet is in proportion to x^(2/3n).
