中文摘要：
提出一种将模拟退火算法和阻尼最小二乘算法相结合的改进算法，并将其用于零维燃烧模型的建立．以预测值和实测值的偏差及曲线的拟合优度为衡量标准，对改进算法和传统算法进行比较．结果证明，改进算法具有提高零维燃烧模型精度、减少计算时间及对初值的要求、避免病态矩阵和复数结果出现的优点．
英文摘要：
An improved algorithm combining the simulated annea- ling algorithm with the Levenberg-Marquardt algorithm was pro- posed , and then optimized the zero-dimensional combustion model. Taking the deviation of the predicted values and meas- ured values and the curve of the goodness of fit as measure stand- ards, the comparison is carrried out between the improved algo- rithm and the traditional algorithm. Results show that the im- proved algorithm has such advantages as increasing the accuracy of zero-dimensional combustion modeling, shortening the compu- tation time and mitigating the requirement on the initial values, as well as avoiding the ill-conditioned matrix and complex re- suits.
