一、序言照相乳剂的基本成分是卤化银颗粒。它是一种结晶体,具有一定的规律性。各个晶体颗粒的组份、外形、大小等对感光度、反差、解象力等照相性能有很大影响。由于它们都很细微,只能借助电子显微镜进行观测研究。电镜在照相乳剂研究中的应用国外很早就已开始,对照相乳剂性能的提高起了一定作用。随着照相乳剂研究的不断深入,电镜在该领域的应用正在越来越被人们所重视。 First, the preamble Photo emulsion is the basic component of silver halide grains. It is a crystal, with a certain regularity. The composition, shape, size and the like of each crystal particle have a great influence on the photographic performance such as sensitivity, contrast and resolution. Because they are very subtle, can only be observed by means of electron microscopy. Electron microscopy in the study of photographic emulsions abroad has long been started, improve the performance of the photographic emulsion played a role. With the deepening of research on photographic emulsions, the application of electron microscopy in this field is getting more and more attention.
