摘　　要：实验研究了顺时针、逆时针转动的哑铃畴(ID,IID)畴长与缩灭场的关系.结果显示,顺时针转动和逆时针转动的哑铃畴的缩灭场明显不同.对于同样畴长的ID,IID,顺时针转动的缩灭场高,较稳定,对应负的VBL;逆时针转动的缩灭场低,不稳定,对应正的VBL.实验首次验证了正、负布洛赫线模型是合理的.The relation between domain length and collapsed field of clockwise and counterclockwise rotating dumbbell domains(ID,IID) is studied experimentally.The results show that the collapsed field of clockwise rotating dumbbell domains is different from that of the counterclockwise rotating dumbbell domains.For the same domain length of ID and IID,the collapsed field of clockwise rotating dumbbell domains corresponding negative VBL is more stable and high.On the contrary,the collapsed field of counterclockwise rotating dumbbell domains corresponding positive VBL is unstable and low.The model of positive and negative Vertical Bloch line is verified firstly.
