| 摘 要： | 采用拉伸实验的方法。研究了形变速率对半晶聚乙烯薄膜拉伸性能的影响。根据其应力-应变曲线的形状，得出聚乙烯具有两个屈服点，研究了这两个屈服点与拉伸速率的关系。并从微观结构的角度对此进行了解释。

| Abstract: | The effect of drawing speed on the strai n nature of semi crystal polyethylene was studied using the method of the plastic tensile testing. It is found that there are two yield points on each curve, base d on the shape of the stress-strain curves. The relationship of two yield point s with tensile testing was studied and expressed on the microstructure. |
