摘　　要：通过对高分子聚合物细观形变过程的分析，提出形变区增殖的观点，由此导出较简洁的弹塑性本构方程，讨论了不同参数条件下应力～应变曲线形状的变化，与文献实验结果基本一致。According to the analysis on micro-deformation process of polymers,the author proposes a new conception of deformed region' s multiplication, from which an explicit elastic-plastic constitutive equation can be deduced. The cliaracteristics of stress-strain curves in different parameter conditions are discussed. which are consistent with some experimental results of some references in principle.
