摘 要: | 本文用逐步逼近法得到了粘性流体运动的自型问题的微分方程(1.1~1.4)的分析解Проснак(1969)用小参数法也得到了这些方程的解.但他把控制方程变换成为一组线性变系数微分方程.本文则把控制方程变换成为线性常系数微分方程.

Abstract: | This paper presents a step-by-step approximating method to obtain the analytical solutions of the differential equations for the self-similar problems of viscous fluid flow (1.1-1.4). Prosnak (1969) obtained solutions of these equations by using a small parameter method, but he reduced the governing equations to the linear differential equations with constant coefficients. |
