天然气水合物的研究现状和前景

天然气水合物是继煤、石油和天然气等能源之后的一种潜在的新型能源，是在高压、低温条件下形成的冰状固体物质，它广泛存在于极地地区，通常与永冻土带的近海和深海以及陆架和岛屿边缘密切相关。本文介绍天然气水合物的概念，物化性质等，综述了国内外天然气水合物的研究现状并指出其发展趋势，最后得出，天然气水合物的研究意义重大。

The Status and Prospects of Research and Exploitation of Natural Gas Hydrate

The gas hydrate, being a solid material, is formed from the methane and water under the high - pressure and low -temperature, exists worldwide in the polar region, normally associated with onshore and offshore permafrost, and in sediment of outer continental and insular margins. Natural gas hydrate has become an exciting national and international research issue over the past few years because of its abundance and its potential role as a fuel. The article starts with the concept and the physical chemistry of the gas hydrate and then summarize the course of its being discovered and the course of its original investigation. The actuality and the trend of the study on gas hydrate have been summarized. In a word, the researches of the gas hydrate are very important.
