摘　　要：介绍了元素势能法的原理,加入热力学第一定律计算系统的绝热火焰温度,采用最速下降法和牛顿迭代法对其进行求解。编写了部分燃料燃烧系统的化学平衡计算软件,分别以甲烷和正庚烷为例,将其与CHEMKIN-EQUIL模块的计算结果进行对比分析,结果吻合度较好。The principle of element potential method was introduced, and meantime the first law of thermodynamics was added to calculate adiabatic flame temperature, the steepest descent method and the Newton iteration method were used to solve the equations. In addition, a program for chemical equilibrium calculation of some fuel systems was designed, which have similar computed results with CHEMKIN-EQUIL in methane and n-heptane combustion system.

关 键 词：燃烧系统 化学平衡 元素势能法
