一、序言卤化银微粒晶体吸收光线后,在晶体内产生了游离电子和游离孔穴,这些陷阱,使电子与银离子结合后,促进银的生长,同时也产生和释放卤素,这就是卤化银的照相感光过程。照相感光理论,历史上有两个转折形成 First, the preface Silver halide crystal particles absorb light, the free electrons generated in the crystal and free holes, these traps, the electron and silver ions combine to promote the growth of silver, but also produce and release of halogen, which is silver halide Photographic process. Photographic sensation theory, history has two turning points
