摘　　要：用比三维有限单元法更为简单的方法──半解析法，计算了塑料板材挤出机头中三维非牛顿熔体流动，使问题大为简化．This paper gives a new method, the semi-analytic method, which is more convenient than the three-dimensional finite element method. It is demonstrated that the problem which calculates the three-dimensional non-newtonian melt's flowing in the extrusion nose of plastic sheet is greatly simplified.

关 键 词：板材挤出机头 非牛顿熔体 半解析法 塑料 流动
