| 摘 要： | 为了精确得到大陆地震震源位置，利用模拟退火法对大陆地震参数进行反演，并对改变算法中相关参数后的反演结果进行分析，表明反演精度受降温速度和收敛阈值的影响较大，初始温度只影响迭代次数，模拟退火法在对模型参数进行全局搜索情况下能获得质量较好的最优解。

| Abstract: | Seismic positioning is one of the most classic and basic problems in seismology. Improving the accuracy of seismic positioning has also been one of the important objectives of seismological application and research. In this article, mainly using the method of simulated annealing to continental earthquake parameters inversion, and the numerical simulation test was carried out with Matlab. The parameter setting, convergence function and convergence threshold of the inversion result are analyzed. The results show that the simulated annealing method can obtain the optimal solution with good quality and the model parameters are searched globally. |
