一、引言我们在1967年发现一些材料在真空紫外照射之后降解了的吸收系数在大气放入后有逐步回复的现象。国外也有类似的报导并称之为漂白(bleaching)现象。因此原位测定材料在真空紫外环境中的吸收系数就显得十分必要了。材料在真空紫外下吸收系数的变化不是均分在各个波段上的。比如铝阳极氧化在可见到
I. INTRODUCTION We found in 1967 that the absorption coefficient of some materials degraded after vacuum ultraviolet irradiation gradually recovered after the air was put in. A similar story is reported abroad and is called bleaching. Therefore, in-situ determination of the material in the vacuum ultraviolet environment, the absorption coefficient is very necessary. Materials under vacuum UV absorption coefficient changes are not evenly divided in each band. Such as aluminum anodizing can be seen
