通过对影响吸附时间的因素的分析，作者认为：煤阶、灰分、温度、显微煤岩类型、割理发育程度及煤样粒度等参数是影响吸附时间长短的最重要的因素。
By analysis on the factors which affect desorption time , the authors considered that coal rank , ash content , temperature , microlithotype s , the developed degree of cleat and the grain size of coal samples are the most important factors to affect desorption time .
