摘　　要：针对二维多孔隙介质波动方程的参数孔隙率的识别问题,考虑模拟退火法的全局收敛特性,结合求解不适定问题的Tikhonov正则化方法,构造出正则化模拟退火算法.数值实验的结果表明此算法能够有效地处理参数识别问题.We constructed a regularization simulated annealing algorithm by considering the characteristics of global convergence from the simulated annealing method,and introducing the Tikhonov regularization method for solving ill- posed problems, aiming at the recognition problem of parameter porosity of two-dimensional porous medium wave equations.The results show that this algorithm can effectively deal with the parameter identification problems.
