摘　　要：针对瓦斯吸附常数测定实验中瓦斯吸附量出现负值的问题,从瓦斯吸附量相关参数、测量误差方面进行分析,得出了煤样质量损失、空罐容积误差、真密度误差、高压吸附平衡时间是影响瓦斯吸附量出现负值的主要因素,并提出了解决方法,为准确地测定瓦斯吸附常数提供了参考。To explain and solve the phenomenon that the negative value of gas adsorption appeared in the gas adsorption constant tests, the relative parameters of gas adsorption volume and the measurement error were analyzed, and the results show that the coal mass loss, empty tank volume error, true density error and high pressure adsorption equilibrium time are the main factors contributing to the negative value of gas adsorption. And the solving methods are proposed to provide reference for the accurately determination of gas adsorption constant.
