中文摘要：

本文对现有煤的瓦斯解吸的研究现状进行了阐述;阐述了外加物理场对煤的瓦斯吸附解吸的研究及其机理;并分析了这些研究成果的优缺点。简单说明了煤的瓦斯吸附解吸的研究方向。外加物理场主要是通过作用于煤样使其变性进而改变煤的吸附解吸特性。外加物理场对煤的瓦斯吸附解吸的研究虽起步晚但也取得了长足的进步和丰硕的成果。并提出建议：改变外加物理场作用方式,变离线式作用为在线作用研究外加物理场对煤的瓦斯吸附解吸及其作用机理。

英文摘要：

In this paper, the current research situation of gas desorption in coal is described, and the research and mechanism of gas adsorption desorption of coal by applied physical field are expounded. The research direction of gas adsorption and desorption of coal is simply described. The external physical field is mainly through the action of the coal sample to make it change and then change the adsorption and desorption characteristics of coal. The research on gas adsorption and desorption of coal by external physical field has made great progress and fruitful results. And some suggestions are put forward： to change the effect of external physical field, and to study the effect of the physical field on the gas adsorption and desorption of coal and its mechanism.
