从熔体中结晶的聚合物的结晶动力学受样品1、2的力学历史的影响，这是众所周知的事实。无应变样品的结晶半衰期比应变在合适温度下没有通过松弛完全消除的样品大3、4。这被称为“取向诱导”或“应力诱导”形核。
IT is a well-known fact that the crystallization kinetics of polymers crystallizing from the melt are influenced by the mechanical history of the sample1,2. Strain-free samples show a larger crystallization half-time than samples in which the strain has not been completely removed by relaxation at a suitable temperature3,4. A larger number of nuclei has been assumed to be present in strained samples than in strain-free ones. This has been called “orientation-induced” or “stress-induced” nucleation.
