根据吴守恒聚合物共混体的脆韧转变的逾渗模型，从能量转换的角度研究了聚合物共混体的脆韧转变过程，并得到在脆韧转变点材料参数及有关的物理量之间关系的方程式，从这一方程出发，讨论了增塑剂、形变速率对聚合物共混体脆韧转变的影响，结果与实验一致。
According to the ductile-to-ductile percolation model of Wu Shoulong polymer blends, the brittle-ductile transition process of the polymer blends was studied from the perspective of energy conversion. The brittle- Based on the equation, the effects of plasticizer and deformation rate on the brittle-ductile transition of polymer blends were discussed. The results are consistent with the experimental results.
