摘　　要：　从电流扩散方程和磁扩散方程出发,研究了在瞬态过程中螺旋型爆磁压缩发生器(HMFCG)的电流密度在螺线管导线中的分布以及感应电流密度在金属套筒中的分布情况,分析计算了爆磁回路初始充电过程中频率对HMFCG电感和电阻的影响,计算结果与实验测量吻合;这为进一步完善校正程序,更好地描述爆磁压缩过程奠定了基础。The distribution of the current density in the wire and induced current density within the armature for a Helical magnetic flux compression generator (HMFCG) are studied based on the solutions of the current and magnetic field diffusion equations. The HMFCG inductance and resistance are calculated analytically during the transient process, and the agreement between the numerical results and the experimental one are quite satisfactory.
