根据甲烷燃烧过程的热力学性质，用Fortran程序研究了在绝热反应器中甲烷燃烧过程中的有关问题.分析了在绝热反应器中甲烷用量恒定时，不同量的空气对燃烧温度、化学组成、流动能及热传递能的影响.实验表明，燃烧过程中使用过量的空气且没有离解反应发生时，其中有2种状态具有相同的组成，同时xN2和xO2也会增大；当有离解作用存在时，将伴随有不可逆反应发生.

Based on the thermodynamic properties of combustion process,methane combustion process in the adiabatic combustor was analysed by Fortran program. When the quantity of methane was definite, the effect of different amount of air used on the temperature, chemical composition, flow energy, heat transfer energy and irreversibility of the combustion process were investigated. It was found that two states had the same compositions, and xN2 and xO2 in these states would increase when the amount of air was over supplied into the combustion and no dissociation. Under the condition of dissociation the irreversibility was easily to occur.
