摘　　要：利用高温高压气体吸附分析仪,研究了不同压力阶段条件下温度对瓦斯解吸规律的影响,得到了各个压力段的瓦斯累计解吸量随时间变化的实测曲线,进而得到累计解吸量与时间的函数关系式。实验结果表明:在各个解吸压力段内,不同温度的瓦斯累积解吸量不同;在相同压力条件下,温度越高,煤粒瓦斯解吸越容易;各个压力段内,不同温度的瓦斯累积解吸量与时间的关系均能拟合成统一的函数关系式。The high temperature and high pressure gas adsorption analysis device had been used for testing the influence of temperature on methane desorption under different pressure stages. The study found the experimental curve of the cumulative amount of gas desorp- tion with the change of time, and then obtained the function of the cumulative amount of gas desorption and time. The experiment re- suits show that with different temperature, the accumulated gas desorption quantity is mutative in the desorption pressure within each segment. Under the same pressure, it is easier for gas desorption when the temperature is higher. Gas content at each pressure segment can be fitted as a function with time.
