REVIEW OF EXPERIMENTAL STUDIES ON TRAN SIENT PHASE TRANSFORMATION OF WATER VAPOR IN SHOCK TUBE

从激波管内水汽瞬态相变实验研究的角度出发，探讨利用激波管理论及实验技术应用于人工影响降雨、消雹所涉及的云雾瞬态相变问题。首先介绍利用激波管研究水汽瞬态相变的概况，并介绍一些特殊激波管及实验状态的控制。然后介绍激波管内水汽相变过程研究的测试原理及方法。最后讨论在研究爆炸方法进行人工降雨、消雹和自然闪电、雷击等问题时。

From the view of experimental studies of transient phase transformation of water vapor in shock tube, the prospect of using theories and techniques of shock tube for experimental studying physics of cloud and fog in the area of weather modification is presented. In the first, the general situations of research about transient phase transformation used by both ordinary and special shock tubes, including some experimental condition controls, are introduced. Then, some principles and methods about the measurement in phase transformation process are described. In the last, some methods and contents on studying microphysical process during rain stimulation and hail mitigation by artificial means, such as effects of blast waves on cloud and fog, with applications of shock tube techniques, are discussed.
