液化气体必须依赖高压或低温才得以维持其液态，因而其面临的安全性问题比通常的液体或气体更为严峻。文章回顾了世界上液化气体储运安全领域已有的研究成果，分析了液化石油气和液化天然气等可燃液化气体在其储运过程中存在多种安全性问题，重点介绍了容器破裂前的热响应，沸腾液体膨胀蒸汽爆炸（BLEVE），燃气在空气中的扩散和液化气体燃烧等方面的研究进展和取得的成果，以及根据这些成果为理论依据提出的可燃液化气体储运的安全措施。

Current Research Situation of the Safety in the Storage and Transpor tation of Combustible Liquified Gases

For the liquified gases to maintain th eir liquid state,it is necessary to depend on high pressure and low temperature,which brings a safety problem more severe than conventional fluids or gases.In t his paper,the existing achievements in the research on the safety in the storag e and transportation of liquified gases in the world are reviewed,many safety problems existed in the storage and transportation of combustible gases (LPG and LNG,etc.) are analyzed and the progress and achievements in the research on the vessel heat effect before it is broken,the boiling liquid expansion vapour expl osion,the diffusion of burnt gas in air and the liquified gases combustion,etc.a re emphatically introduced,and based on which,the safety measures in the storage and transportation of combustible gases are presented also.
