摘要

描述了用于电缆绝缘子的EPR(乙烯-丙烯橡胶)的/spl γ辐照对电导率的影响。辐照产生电导率的永久和暂时变化。退火降低了暂时增加的电导率，相对于未辐照样品的电导率。电导率的永久变化可能是由化学变化引起的，而暂时的变化可能是由物理过程引起的，如/spl γ /-辐照激发的载流子的捕获。

Effect of /spl gamma/-irradiation on electrical conductivity of EPR with filler

The /spl gamma/-irradiation effect on electrical conductivity is described for EPR (ethylene-propylene rubber) formulated for a cable insulator. The irradiation produces both permanent and temporary changes in the conductivity. Annealing reduces the temporarily increased conductivity toward that of unirradiated samples. The permanent change in conductivity is probably caused by a chemical change and the temporary change is likely due to such physical processes such as the trapping of carriers excited by /spl gamma/-irradiation.<>
