摘　　要：针对地球物理反演的非线性问题,对模拟退火算法计算效率的影响因素进行了详尽的分析,并通过引入均匀试验设计理论,使在庞大的解空间中随机选取的候选解更加均匀,少量的目标函数计算就能了解目标函数解空间的性质,从而提高模拟退火算法的计算效率。对退火温度的选取方法进行了讨论,并提出了改进方法,使退火温度的选取具有自适应的特点,通过在地震静校正中应用,证明了改进算法的有效性。In view of nonlinearity characteristic of geophysical inversion, the influencing factors of calculation efficiency in analog annealing algorithm have been analyzed in detail. At the same time, the introduced uniform design and simulation theory makes random chosen candidate solutions more homogeneous in the vast solution space and furthermore a few target function calculations makes clear of the properties of their solution spaces and thus enhances the computation efficiency of analog annealing algorithm. The choosing methods of annealing temperature are also discussed in the paper and moreover the improved method has been presented. All achievements stated above make the choice possess self-adaption characteristic. Through the application in seismic static correction, the improved method has been proven effective.
