摘    要：在简化条件下，对粉末注射成形喂料熔体在圆柱状模腔内作一维非等温流动进行了分析，用有限差分法建立了控制方程对应的差分方程组，并给出了差分方程组的求解步骤.

Abstract: A one dimensional non isothermal flow model for feedstock melt in a cylindrical mold cavity is ana lysed under the simplified conditions. A series of difference equations are obtained from the governing equations by a finite difference numerical method and the solving procedure is also presented in this paper.
