摘　　要：通过微波对溴化银乳剂胶片的照射可以达到使感光胶片增感的目的 .研究表明 ,短时间的微波照射就可以使溴化银胶片的感光度有明显提高 ,而一定时间的微波照射后 ,感光胶片的感光度并不象外加热方式那样出现衰退的现象 .增加硫金比 ,微波照射后 ,感光度增加较多 ,说明感光中心与 [Ag2 S·Ag]+ 有关 .并且 。It was fornd that the photographic film could be sensitized by a microwave irradiation.The film sensitivity could be enhanced greatly after a short time microwave irradiation.Unlike film heated,its sensitivity did not decrease after a long time microwave irradiation.When the S/Au ratio was raised,the film sensitivity was improved more.The reason is that the center of sensitivity is relevant to [Ag 2S·Ag] +.In addition,The effect of microwave on the film sensitivity could maintain only a few hours after the microwave irradiation.
