摘　　要：银盐扩散型CTP(Computer To Plate)版材基于银盐扩散转移原理 .本文利用高分辨率的场效应扫描电子显微镜及CCD等手段研究了几种因素对该类版材物理显影银堆积状态及物理显影过程的影响 .清晰地观察到不同曝光区物理显影银的堆积状态 ,在弱曝光区 ,银颗粒堆积紧密 ,是版材具有亲油性的主要原因 .使用不同类型络合剂分别得到了颗粒状、树枝状等各种形态的物理显影银 ,表明络合剂对银颗粒形态有显著影响 .通过CCD装置对版材上物理显影过程的实时原位监测 ,从动力学的角度解释了络合剂、显影温度对物理显影银堆积状态的影响 .Silver halide CTP(Computer To Plate) Plate is based on silver halide diffusion transfer principle. In this paper, the influences on the aggregation of physically developed silver were studied with high resolution SEM(Scan Electronic Microscope). The silver clusters in different exposure areas were observed clearly. The silver particles aggregated more closely in low exposure area which usually showed oleophilic. Different shapes of developed silver, such as spherical, branch like, were obtained when various complexing agents were used. The physical developing process was monitored with a set of one dimensional CCD(Charge Coupled Device). The dynamic curves were employed to explain the aggregations of the developed silver.\;
