摘　　要：研究了微波照射对卤化银感光材料照相性能的影响。微波照射下不会导致卤化银乳剂自发光解。通过量子化学计算可知 :卤化银乳剂的照相性能和整个卤化银晶体中静电势的分布有关 ;微波照射可以改变卤化银晶体中的静电势分布 ,从而使卤化银感光材料的照相性能发生变化。微波照射对于硫增感卤化银乳剂照相性能的影响大于对未经硫增感的卤化银乳剂。微波照射对于卤化银乳剂照相性能的影响有一定的“弛豫时间”。The effects of microwave irradiation on the photographic properties of the silver halide emulsion were studied.The irradiation of a microwave did not make the silver halide emulsion photolyze spontaneously.The quantum chemistry calculation showed that the photographic properties of a silver halide emulsion depended on the distribution of stationary potential in the whole crystal and the irradiation of the microwave influenced this distribution resulting in changes of the photographic properties of the emulsion.The irradiation of the microwave affected the sulfur sensitized emulsion more than the primitive one.After irradiation the effect of the microwave decreased with increase of the time.
