| 摘 要： | 本文采用表面修正线圈对二极铁磁场一阶（α线圈）和二阶（β线圈）指数进行修正。当分别通电流I=3A时，α=0.052、β=0.27。实验结果与理论设计符合得很好，α值相差约1%，β值相差约2%。 |

| Abstract: | Correction surface coils were used to modify the first (α coils) and second (β coils) field indices. When the current of correction coils is 3 A, α=0.052，β=0.27, respectively. The experimental results match with theoretical expectations, and the deviation for α is about 1%, the deviation for β is about 2%. |
