利用红外热像技术成功地观察到了拉伸过程中聚合物薄膜的局部生热现象。这些图像表明，发生分子取向和微晶重排的高温部分主要位于颈缩部分的末端，对于表现出颈缩的聚合物，或者对于没有表现出颈缩的聚合物，在整个膜中均匀地出现。产生的热量可以粗略估计，和估计的热量和机械功之间的关系导致了热力学研究。© 2006 Wiley Periodicals，Inc.应用聚合物科学杂志100：2895-2900，2006
The local heat generation that accompanied tensile drawing of polymer films was successfully observed by infrared thermography as a series of temperature distribution images. These images showed that the high temperature part where rearrangements of molecular orientation and microcrystallines occurred was located mainly at the end of the necked part for the polymers that exhibited necking or appeared uniformly throughout films for the polymers that did not exhibit necking. The generated heat could be roughly estimated, and the relation between the estimated heat and mechanical work led to the thermodynamic investigation. © 2006 Wiley Periodicals, Inc.
