对L2型月牙波的产生和演化进行了一系列实验研究。所考察的影响因素包括不同试验装置的影响、I类和II类不稳定性的竞争以及有限水深和波浪陡度的影响。介绍了最不稳定的扰动波作为月牙波产生的实验室实验技术。得到了触发月牙波的临界波陡度，并与理论结果进行了比较。讨论了L2型新月波和本杰明-费尔不稳定性的演化特征。
A series of experiments on generation and evolution of L2-type crescent waves are performed. The examined influencing factors includes the effects of different experimental setups, competition of class I and class II instabilities and the effects of finite water depth and wave steepness. The most unstable perturbation waves are introduced as a laboratory experiment technique of crescent wave generation. The measured critical wave steepness for triggering crescent waves is obtained and compared with theoretical results. The evolution features of L2-type crescent wave and Benjamin–Feir instability are discussed.
