摘　　要：为了研究汽轮机内湿蒸汽两相流的湿度、水滴的粒径和分布,以及水滴的带电特性,近年来国内外发展了一些新的测量技术,包括光散射法、微波法、电容法、图像法等。本文对这些新的测量技术作了较为全面的概述和介绍,对不同的测量方法进行了比较和分析,并对测量技术的发展进行了展望。For the purpose of studying wet steam flow in steam turbine, to measure the wetness, size distribution of droplets and static electricity characteristic of wet team, some measurement techniques are developed recently, including light scattering method, microwave resonant cavity perturbation method, electrical capacitive method and image method. This paper presents these new methods in detail. Different methods are compared and analyzed and the development tendencies are also looked ahead.
