摘要
文中详细介绍了利用光透过率法测量煤粉颗粒比表面积平均直径的原理和测量装置，给出了实际测量数据，取得了与筛分法一致的结果，使用普通的光电测量装置，本法测量极限误差一般可小于２％ 。
This paper describes the principle and apparatus of a light transmission method to measure the volume-surface mean diameter of coal powder particles and reports the experimental result which is consistent with that of the size test.Using this photoelectronic measuring apparatus,for general purpose the measurement precision of this method is up to 2% easily.
