A new on-line method to determine the particle size distribution using light ex-tinction is proposed in this paper.

提出了用光透消光法(或称全散射法)对颗粒尺寸及其分布进行实时在线测量的方法。

The color of the aluminum-anodic-oxidized membrane will be yellow or black due to different electrolytic tinction time.

铝阳极氧化着色膜随电解着色时间不同而呈现黄色膜和黑色膜。
