摘　　要：在氙灯暴露试验中可以用聚苯乙烯标准塑料片作为辐照剂量的校准物使用。该文主要是针对老化后的聚苯乙烯标准塑料片评价方法的摸索。通过聚苯乙烯标准塑料片在经受一定辐照剂量后,用透射法和反射法测得L、a、b值,通过比较L、a、b值数据,发现反射法更适于聚苯乙烯标准塑料片老化后的评价。The polystyrene plastic sheet can be used as the irradiation calibrator in xenon lamp exposure test.This paper mainly focuses on the evaluation method of aging polystyrene plastic sheet.The values of L,a and b were measured by transmission method and reflection method after the standard polystyrene plastic sheets exposed to a certain dose of radiation.By comparing the values of L,a and b,it was found that the reflection method was more suitable for the evaluation of the standard polystyrene plastic sheet after aging.
