模拟退火法是一种以统计原理、热动力学和多变量概率理论为基础的随机综合最优化技术。本文将模拟退火法应用于线性磁力和非线性电阻率反演问题。地层可表现为由内部磁化率成导电率的小元素块组成,这样即可模拟较大的构造。文中用模拟退火法计算了引起实测异常场曲线的一些特定的物理特性的分布。我们概要介绍了模拟退火法及应用,随后专门 Simulated annealing is a stochastic synthesis optimization technique based on statistical theory, thermodynamics and multivariate probability theory. In this paper, the simulated annealing method is applied to the linear magnetic and nonlinear resistivity inversion problems. Stratigraphy can be represented by a small elemental mass that has an internal magnetic susceptibility as a conductivity, thus simulating a larger structure. The simulated annealing method is used to calculate the distributions of some specific physical properties that cause the measured abnormal field curves. We outlined the simulated annealing method and its application, and then specialized
