由于高分子化合物的广泛使用和这些材料在合成方面的巨大成就,高分子物体的破坏和不可逆变形过程普遍規律的研究可以列入最重要的科学和技术課題中。有些时候,例如在用人造纤維、橡皮、塑料制造制品时,人們要求高分子材料具有尽可能高的强度。而 Due to the widespread use of polymeric compounds and the tremendous achievements made in the synthesis of these materials, the general laws governing the destruction and irreversible deformation of polymeric objects can be included in the most important scientific and technical subjects. In some cases, for example, in the manufacture of articles made of rayon, eraser, plastic, it is desirable that the polymer material have the highest possible strength. and
