摘　　要：实验采用ZRJ-1型煤自燃倾向测定仪,分别对不同煤样进行不同温度下吸附氧气后的脱附实验。实验得出脱附过程中的氧气的状态变化过程特征曲线,曲线斜率随脱附出的氧气浓度变化而变化。整体表现为2个波峰,其中后1个波峰表现为拖尾峰。不同温度下的煤的物理吸氧量变化规律为随着温度的升高物理吸氧量呈整体下降趋势,在一定温度范围内有波动。The ZRJ-1 coal spontaneous combustion character tester was adopted in this experiment to test the desorption of several coal types under different temperature after they decorate oxygen. Obtaining the change of oxygen of the desorption process curve, the slope of the curve changes with the change of the oxygen concentration, there are two peaks in the whole line, the after peak is tail peak. The oxygen change process curve in the desorption process under different temperature. With the increases of temperature the physical oxygen decreases and has the fluctuation in a certain temperature range.
