摘　　要：基于均匀试验设计方法,提出了一种具有较高计算效率的自动剩余静校正算法。该算法利用均匀试验设计方法在庞大的解空间中确定候选解,利用模拟退火规则来选择候选解,从而用少量的计算就能使候选解在模型空间分布更加均匀,提高搜寻全局最优解的速度。同时采用模型的不同分量的温度参数和退火过程的选取方法,使退火过程具有自适应的特点。该方法克服了常规模拟退火方法所具有的寻优空间不均匀以及不同模型分量的退火过程完全相同的缺陷。通过实际地震资料的计算证明,该方法是合理、有效的。The uniform design-based algorithm developed for dealing with residual static corrections is used to determine the candidate solution in huge resolving space, integrated with simulated annealing approach, in order to increase the speed of searching for the global optimized solution through more uniform distribution of candidate solution in the model space. Also, selecting the temperature parameters and the annealing processes of different model components allows the annealing process to be of adaptive feature. This new algorithm overcomes the shortcomings of the conventional simulated annealing method, such as non-uniform optimizing space and same annealing process in different mode~ components. The case study from seismic data shows that the algorithm proposed in this paper is more reasonable and efficient than the conventional simulated annealing method.
