摘要

本文研究了在以电子加速器的电子射线为辐射源时，剂量率对PTFE辐射裂解的影响。在剂量相同的条件下，剂量率从1.44×10,4,rad/s增至5.75×10,4,rad/s，裂解效率提高3.3倍。剂量率和各断裂参数（单位剂量裂解度α,0,，G,(s）,值等）均成线性关系。当裂解度一定时，剂量率与剂量成反变关系。

Abstract

This paper has studied the effect of dose rate on radiation degradation of PTFE by electron beam irradiation. In the case of same dose, if dose rate increases from 1.44×10,4, to 5.75×10,4, rad/s, the degradation efficiency of the latter was about 3.3 times of the former. There are linear relationship between the dose rate and the scission parameters (e. g. degree of degradation per unit dose and G,(s) ,etc) . In the case of given degree of degradation, the dose rate will varied oppositely with irradiation dose.
