摘　　要：对氢致裂纹产生机制、影响因素、试验技术及数值模拟技术的国内外研究状况进行了综述,并对存在的问题进行了分析,认为在氢致裂纹试验技术及数值模拟技术等方面仍需作进一步的研究。This paper summarized the current situation at home and abroad about the research works on the mechanism, the affecting factors, the testing method and the numerical simulation of hydrogen - induced cracking, and synthetically analyzed the existing problems. It is considered that there are still some projects necessary to carry out a further study on above fields.
