根据容量法测定煤对甲烷吸附常数的技术特点，通过试验分析研究出一种用测定瓦斯含量的脱气仪测定煤对甲烷吸附常数的新方法。 According to the determination of the technical characteristics of the coal adsorption constant on the basis of the volumetric method, a new method for determining the adsorption constant of coal to methane by using a degassing apparatus for measuring the gas content was developed through experimental analysis.
