摘　　要：(100)高氯T颗粒乳剂是一种新型的T颗粒感光乳剂,颗粒的两个(100)主晶面为正方形或矩形。乳剂中常出现棒状大颗粒、四面体状大颗粒、厚颗粒以及立方体和近似球形的小颗粒等非T颗粒。非T颗粒的存在降低了T颗粒的比例,影响乳剂的照相性能。本文通过在制备过程中取样、观察,分析了非T颗粒产生的时间、成因、影响因素以及减少非T颗粒的措施。High chloride tabular grains have two parallel(100)major faces,which are squares or rectangles.During the preparation of the emusions ,rod-shaped grains ,tetrahedron-shaped grains ,thick grains ,little cubic grains and little round grains often appeared,thus decreased the ratio of tabular grains.By sampling during the preparation process and observing with microscopy,we analyzed and studied the time ,the causes,and the influence factors of their formation and the ways to reduce them.
