For the crystalline samples, when the ratio of m( BMI):m(PA1010) varied from 1:100 to 5:100, the jumping-off point of crystalline damaging decreased from 10 000 kGy to 4 500 kGy with the increasing of the content on BMI.

• 对于m(BMI):m(PA1010)比值从0:100到5:100的结晶样品,其结晶损伤的起点随着BMI含量的增加从10 000 kGy下降至4 500 kGy。
