基于均质流假设，研究了ＳＦ６气体与Ｌｉ液间的燃烧反应．在１０１．３２５Ｐａ（１ａｔｍ）下当反应体系处于相和化学平衡时，混合物分数可处理为唯一的状态变量，其他各状态变量表示为混合物分数的函数．分析了体系的密度、温度及各组分浓度对混和物分数的函变关系．按混合物分数的变化可得特征不一的５个状态区域：边界区、相变区、火焰区、冷凝区及核心区，讨论了各区域的特征．计算显示：当ＳＦ６气体与Ｌｉ液混合比接近化学当量比０．７２时，燃烧体系绝热燃烧温度达到最高值３５００Ｋ．最后讨论了熔池温度对燃烧体系热力学参数的影响：熔池温度越高，气相范围越大，气相开始出现所对应的混和物分数值越小
Based on the assumption of homogeneous flow, the combustion reaction between SF6 gas and Li liquid was studied. At 101.325 Pa (1 atm) when the reaction system is in phase and chemical equilibrium, the mixture fraction can be treated as the only state variable, and the other state variables are expressed as a function of the mixture fraction. The relationship between the density and temperature of the system and the concentration of each component on the mixture fraction was analyzed. According to the changes of the mixture fraction, five different characteristic regions were obtained: boundary zone, phase transition zone, flame zone, condensation zone and core zone. The characteristics of each zone were discussed. The results show that when the mixing ratio of SF6 gas and Li liquid is close to stoichiometric ratio of 0.72, the adiabatic combustion temperature of the combustion system reaches the maximum 3500K. Finally, the effects of bath temperature on the thermodynamic parameters of the combustion system are discussed. The higher the bath temperature is, the larger the gas phase range is, and the smaller the fraction value of the mixture corresponding to the gas phase begins to appear
