摘　　要：用ＷＡＸＤ和ＳＡＸＳ方法研究了聚酰胺１０１０的聚集态结构和结晶结构的辐射损伤过程和机理。辐射交联与裂解主要在非晶区和结晶表面或中间相发生；辐射损伤并从这里开始，随辐射剂量增大，非晶化逐渐向晶区伸展，有氢键的（０１０）晶面损伤几率高于（１００）晶面；辐射后效应导致新的交联与裂解生成，主要影响（０１０）晶面的形成与完善，使Ｌ１００及Ｗｃ变小。The radiation effects on the polyamide 1010 samples of various aggregation statesand the crystal damage induced by irradiation have been investigated by WAXD and SAXStechniques, The results indicated that the cross-linking and scission of the irradiatedpolyamide 1010 samples occurred mainly in the amorphous region and interphase (or crystalsurface) and the crystal damage induced by irradiation started from crystal surface,extend-ing into the inner portion of the crystal with increasing radiation dose. The portion of irradi-ation damage for the(010)plane is greater than that for the(100)plane. The post-radiationeffects induced by heat-treatment, a further crosslinking and scission affect the formationand perfection of the(010)plane and cause a decrease of crystallite size L100 and the cryst-sllinity of the samples.
