中文摘要：

采用pulse calorimeter仪器,分别研究了在湿的氮气气氛下和湿的氧气气氛下的相对湿度对低阶煤低温氧化过程的影响.结果表明,在湿的氮气气氛下,相对湿度对凝结热（包括吸附热）有显著的影响,低阶煤低温氧化过程释放的热随着湿度的升高而增加;同样在湿的氧气气氛下,随着湿度的增加体系放出的热明显增加;另一方面,随着温度的增加,体系的凝结热和吸附热减少;而在湿氧气下体系释放的热随温度的增加起始先减少后增加.

英文摘要：

Effect of the relative humidity of both nitrogen and oxygen on low temperature oxidation of low rank coal is investigated respectively using pulse calorimeter in this paper. The relative humidity affects remarkably both the condensation heat and adsorption heat of the process under wet nitrogen. The exothermal value of low temperature oxidation of low rank coal increases with the relative humidity of wet nitrogen. The effect of the relative humidity on exothermal value of the process under wet oxygen is same as under wet oxygen. On the other hand, the condensation heat and adsorption heat decrease with temperature under wet nitrogen, while exothermal value of the process decrease with increase of temperature at first, then increase with temperature.
