摘　　要：对蒸汽透平中流动湿蒸汽湿度测量的重要性和这一课题的研究进展以及研究现状进行讨论 ,分析比较后认为加热法是一种比较合适的蒸汽湿度测量方法。详细介绍了这一方法的原理 。In this paper, the importance of wetness measurement for the flowing wet steam in turbine is discussed , the historical and current development of this problem are also introduced. Amomg the many methods for measuring the wetness of flowing wet steam, the heating method is one of the most suitable methods. Because it has a simple principle and high accuracy. In this paper, the implement of heating method is discussed and analyzed in detail. In the mean time, this paper presents an improved heating method for measuring the wetness of flowing wet steam which has been adopted in order to overcome the shortcomings of the former heating method.
