摘要:
用表面磁荷法可以快速高精度计算带有磁轭屏蔽的超导MRI磁场。对于漏磁场的屏蔽,当用材量保持不变时,单层屏蔽的屏蔽能力优于多层屏蔽;屏蔽材料的用材量和磁化率均存在最佳值范围。
Abstract:
Using surface magnetic method, you can quickly and high -precision. Calculate the superconducting MRI magnetic field with a magnetic shield. For the shielding of the leakage field, when the material is maintained, the shielding capacity of the single -layer shielding is better than the multi -layer shielding; the material and magnetization rate of the shielding material have the best range.
