摘要 从电磁场分析角度出发,采用时域有限差分法对电磁场数据进行计算分析,提取土壤电离的信息,将整数微分进化策略与Matlab分布式计算相结合,提出针对任意均匀分布土壤建立LIEW动态模型的方法,优化确定LIEW动态模型参数——土壤电离临界电场强度和电离时间常数。 From the viewpoint of the electromagnetic field,using the finite difference time domain method （FDTD） to analyze the electromagnetic field and extract the information of the soil ionization.Combine the integral differential evolution strategy and the Matlab distributed computing to attain and optimize the parameters of the LIEW dynamic model-the critical electric field intensity of soil and the ionization time constant.In this paper,the method to building the LIEW dynamic model for any kind of homogeneous soil is presented.
