摘要
ＡｇＣｌ乳剂转化为ＡｇＣｌＢｒ乳剂的过程中，颗粒外形逐渐变圆，颗粒体积可能增大几倍；同时，颗粒分布变差系数缩小。颗粒体积的这种增大表明，转化过程伴有颗粒之间的非奥氏成熟过程引起的物质传递。这种传递可能是由于有大量颗粒在转化过程中迅速碎裂，并将其物质转移到生长中的颗粒上去了。
It is observed that during the process of converting cubic AgCl emulsion to AgClBremulsion,The shape of grains become round gradually, the mean volume of grains increasesserveral times and the variation coefficient of grain size distribution tends to decrease. The enlargement of the grain volume can be explained as that besides of Ostwald ripenning thereexsists material transfer between grains accompaning the conversion process,some grainsare broken into very small pieces and dissolved very quickly,the material contained in thosegrains is transfered to the growing grains.
