摘要: 根据磁场、流函数和感应电流的解析公式，研制了间接馈电爆磁压缩发生器充电和爆磁压缩过程计算程序MFCGⅢ。用MFCGⅢ计算了实验模型，其结果与测试结果符合较好。因此MFCGⅢ可对实验提供优化设计，并且可分析、解释MFCG实验中有关的物理问题。Abstract: In this paper , computational code MFCGⅢ of the explosive magnetic field compression generator (MFCG) are developed based on the analytic formulas of magnetic field , stream function and induced current for the process of charge and compression. Under the same conditions , computational results obtained by 2-D MFCGⅢ code coincide with results obtained by experiment. Therefore , the design optimization can be achieve by MFCGⅢ for MFCG tests and the concerned physical problems can be analyzed and explained by MFCGⅢ in MFCG tests．
