摘要
分析研究了γ辐照引起抗冲聚苯乙烯（ＨＩＰＳ）微现结构改变与宏现力学性能之间的联系，并详细讨论了ＨＩＰＳ力学性能辐照效应的机理。
The correlation between the γ-irradiation induced changes in microscopic structure of HIPS and its macroscopic mechanical properties is investigated. The mechanismof the effects of γ-irradiation on the macroscopic mechanical properties of HIPS is also discussed in detail.
