摘要

一种改进的显微摄影程序已被开发，以加快分析乳剂的尺寸-频率方法。该方法采用薄膜条和标尺同时投影的方法。将1000个油球分类成适当大小的层段，只需以前所需时间的一半左右。研究了微型均质机(a)长时间对乳剂的影响和(b)制造乳剂的各种方法。超声作用30分钟后，乳剂无凝固现象。

Emulsification with ultrasonic waves. I. Evaluation of the minisonic and a modified analysis procedure.

A modified photomicrography procedure has been developed to speed the size-frequency method of analyzing emulsions. This method employs a film strip and rule simultaneously projected. Classification of 1,000 oil globules into the proper size intervals can be done in about one-half of the time formerly required. The Minisonic homogenizer was investigated for ( a ) the effect of long insonation periods on emulsions and ( b ) various methods of manufacturing the emulsion. No coagulation of emulsions occurred when exposed to ultrasonic waves for thirty minutes.
