摘　　要：实验研究了直流偏场(Hb)和面内场(Hip)联合作用下,液相外延石榴石磁泡薄膜中第Ⅰ类哑铃畴(ID)畴壁中垂直布洛赫线(VBL)的解体.通过实验得到了3个重要的面内场Hi(p1),Hip*和Hi(p2).通过“切尾”实验可以证明面内场对垂直布洛赫线链(VBLs)的丢失有影响;而VBLs的丢失又影响到了ID的行为.The annihilating process of the first king of dumbbell domains （IDs） in garnet bubble films subjected to an in-plane field Hip was studied experimentally. Three important in-plane fields had been obtained,which were Hip^（1） , Hip^＊ and Hip^（2） . By the experiment of tail-cut,it was found that Hip played an important role during the annihilating of VBLs in the wall of ID. As a result, the losing of VBL in the wall of ID affected ID＇s indeed.
