摘　　要：本文讨论了含有BL线和BL串的磁泡畴壁的动力学.应用磁畴壁运动的基本方程推导出作用在单个BL线和正常磁泡畴壁的动力学反作用力并由含有BL串的畴磁壁运动的耦合方程给出这些力的合成形式.The dynamics of domains containing BLs (Bloch lines) is reviewed, regarding the positions of individual or clustered BLs as dynamical variables. Based on the fundamental equations of magnetic domain wall motion, the dynamic reaction forces on one BL and one normal (without BLs) cylinder domain ara derived. Combination of these forces gives coupled epuations of motion for a domain containing a cluster of BLs.
