为研究不同加压速率对吸附性能的影响，采用美国康塔仪器公司研制的iSorb HP2高压气体吸附分析仪对门克庆矿、沙曲二矿、阳泉五矿3种不同煤阶煤样，进行了不同加压速率下的瓦斯吸附常数对比测试。结果表明，加压速率对瓦斯吸附常数影响非常明显；对特定煤阶煤样，随着加压速率增大，吸附常数a有减小趋势，吸附常数b有增大趋势，煤阶越高，瓦斯吸附常数受加压速率的影响程度越大。因此，对于不同煤阶煤样，加压速率应适当调整，以提高其指导现场应用的作用。

In order to research the influence of different pressurization rates on absorption property, iSorb HP2 high-pressure gas ab-sorption analyzer developed by U.S.Kangta Corporation was applied to testing methane absorption constant of 3 coal-ranks specimen from Menkeqing, Shaqu and Yangquan under different pressurization rates.Results showed that the influence of pressurization rate on methane absorption constant was obvious.For special coal-rank specimen, with rate increasing, absorption constant a decreased and b increased.The larger the coal-rank was, influence degree was larger.Therefore, for different coal-rank specimen, pressurization rate should be changed suitably to preferably guide practice.
