本文评述了各种颗粒尺寸测量方法的发展现状。所介绍方法中,有些方法从原理上讲是新的,如液相色谱法、微波测量法、光导纤维探测法、扩散仪、电迁移率测量等;有些虽是老方法,但采用了新技术和新的操作方法,有了新的发展,如引入激光技术之后,激光衍射仪、全息照相、多普勒速仪、光遮法和相关法等相继出现。本文以较大篇幅介绍了这方面的内容。此外,本文也扼要地评述了颗粒形状和在线分析的研究工作现状。
This article reviews the current status of various particle size measurement methods. Some of the methods presented are new in principle, such as liquid chromatography, microwave measurement, optical fiber detection, diffusers, and electromigration measurements; while some are old methods, they employ new techniques With the new method of operation, new developments such as laser diffraction, holography, Doppler velocimetry, light obscuration and correlation methods have emerged. This article presents a larger space in this area. In addition, this article also briefly reviewed the research status of particle shape and on-line analysis.
