摘　　要：采用有限元方法分析了狭缝口模截面内塑料熔体的流动状态 ,实现的过程是通过MATLAB编程 ,对比了矩形口模和改进口模在速度分布的差异和对流率的影响 ,并将计算分析结果直观地以图形、图像显示出来。Flowing state of plastics melt in slit die was simulated by finite element method based on MATLAB software in this study. The difference of velocity distribution and flow rate between the rectangular die and the mended die were analyzed.The analysis result could be showed in audio visual by a figure and picture.
