摘　　要：随着液化天然气(LNG)在全球中的广泛应用,其存储和运输过程中的安全问题成为研究的重点。其中LNG的泄漏就是危及其安全性最重要的因素之一。简要介绍了国外研究LNG泄漏的实验研究和理论研究,阐述了LNG的物理性质,以及其燃烧、低温、快速相态转变的危险特性,并在其基础上分别讨论了LNG泄漏在一定条件下可造成的危险后果。同时提出了能预防或减小LNG泄漏带来危害的安全技术措施。With wide application of liquefied natural gas （LNG） in the world, the security issue has become the emphasis of research in its storage and transportation process. LNG leakage is one of important factors that can endanger its security. In this paper, experimental and theoretical studies of LNG leakage at abroad were described, physical properties of LNG were discussed as well as hazardous characteristics of its combustion, low-temperature and rapid-phase-transition; On the basis of these characteristics, harmful consequences caused by LNG leakage under certain conditions were discussed. Meanwhile, the safety technique measures which can prevent or reduce the harmful consequences caused by LNG leakage were put forward.
