摘要
首先从理论上论述了温度及变形速度对高分子材料机械性能的影响;然后通过实验予以证实;并求出了屈服应力的实验公式、以及PC材料的热膨胀系数α;最后提出了新的研究课题.
The effects of the temperature and the strain ratio on the mechanical properties of polymeric material were first discussed in theory. It was then confirmed by experiments. The empiric formula of the yield stress and the thermal expansion coefficients α of PC material were der ved. A new subject was finally put forward.
