摘　　要：液化天然气(LNG)的生产和贸易日趋活跃,使得LNG船舶的数量和容量不断增大。大型液化天然气船舶的储罐中储存着大量的LNG,一旦发生泄漏,后果不堪设想。因此LNG船舶的泄漏及相关的安全问题受到人们的高度重视。通过对液化天然气船舶目前发展状况的简单介绍,分析了LNG船泄漏的危险性;在此基础上,从LNG泄漏扩散过程数学模型的研究、风洞实验和物理模拟、现场试验和实时动态仿真模拟等四个方面详细总结和分析了国内外在LNG泄漏扩散过程问题上的研究现状。With the dramatically increasing of production and trade of LNG, the number and carrying capacity of LNG vessels became greater all the time. It became dangerous that too much LNG was stored in tanks of LNG vessel. Should LNG leakage from the storage tank take place, the disaster would be too dreadful to contemplate. So the safety problems, such as leakage and exploration, of the LNG storage tank had been highly paid attention to. In the paper, the developing situation of LNG vessels was firstly introduced, and then the possible hazards from LNG leakage were analyzed. On the basis of the above, four aspects, i.e. Research on mathematic model, wind tunnel experiment, field test and real-time dynamic simulation were listed to account for the current research situation on Leakage and diffusion process of LNG vessels. At the end of the paper, some viewpoints were pointed out.
