中文摘要：

针对以往研究都无法充分说明不同含水率下的煤对瓦斯吸附能力的差异以及水与瓦斯共同作用下的吸附微观机理，从实验出发，结合微观气液二相流的相关理论，通过分析得出，相同初始压力下的定容吸附，吸附速率随含水率的增加而降低，干燥时的吸附速率是含水2％时的22倍；且不同含水率下吸附量随时间的变化服从对数分布，在含水率1％前后结果不同。

英文摘要：

Few researches focused on the effect of different moisture contents in coal on the gas adsorption capability and the microcosmic adsorption mechanism of coal under the combined influence of water and gas. According to the experimental results and the theory of microcosmic gas-liquid two phase flow, it can be known that the adsorption rate for the fixed volume decreased with the increase of moisture content under the same initial pressure, and the adsorption rate for dry coal was 22 times than that for the coal with 2 % of moisture. The adsorption capacity of coal containing different moisture contents followed logarithmic distribution, and the results were different when the moisture content is greater or less than 1%.
