摘　　要：根据在水洞中所作的系列通气超空泡试验,以及国内外的大量相关文献,综述和探讨了通气超空泡实验研究中的几个主要问题.主要内容包括通气超空泡试验中的相似准则考虑;重力场对通气超空流的影响规律;通气超空泡的闭合和气体泄漏问题;通气超空泡的不稳定性机理.最后,对通气超空泡的试验研究方向进行了展望.Based on many documents at home and abroad and a series of ventilated supercavity experiments, conducted in water tunnel, some problems in experimental study of ventilated supercavity are summarized and discussed. The main contents＇ include the similarity criteria in ventilated supercavity test, the influential law of gravity on ventilated cavity flow, closure and gas leakage problem of ventilated supercavity and mechanism of ventilated cavity, instability. Finally, prospect of testing research topics of ventilated supercavity is suggested.
