摘　　要：该文研究了由多枝畴收缩而成的哑铃畴（ⅠＤ、ⅡＤ）在系列脉冲偏场作用下的行为，发现哑铃畴在系列脉冲偏场作用下，随脉冲偏场幅度的增加会出现改变方向以及丢失ＶＢＬ的现象．The behavior of the dumbbells(I D and I D)contracted from multinultibranched domains was investigated experimclltally under series pulse field,It was found that the rotation direction of the dumbbells could be ehanged to the opposite one when the Pulse bias field was increased to a certain amplitude.,and that parts of the vertical bloch tines(VBL)in the domain walls of these dumbbells vanished gradually when thepulse bias field was strong enough.
