PD照相法(即物理显影照相法)以其显著的特点在缩微技术上获得了重要的应用.PD感光胶片解相力很高,从而大大跨进了超缩微领域.它耗银极少,因而具有很高的经济价值.用PD感光胶片制作的缩微平片反差良好,图象清晰,耐磨耐潮,使用寿命长。研制工艺及其分析PD照相原理及一般步骤我们曾于另文叙述过.研制PD感光胶片选择了PD—D型反应,即是最初的光反应产物能使亚汞离子发生歧化反应而形成潜象核。PD感光胶
PD photographic method (ie, physical imaging method) for its remarkable features in microtechnology has been an important application.PD photographic film high phase resolution, which greatly into the field of ultra-miniature.It consumes very little silver, which has a very High economic value.PD photographic film made of microfilm contrast is good, the image is clear, wear-resistant moisture-resistant, long service life. Development Process and Analysis PD photographic principles and general steps We have described elsewhere.Development of PD photographic film selected PD-D-type reaction, that is, the first photoreaction products can make the mercury ion disproportionation reaction and the formation of a latent image nuclear.
