| 8. | Old mri machines cannot be used for cardiovascular examination as they do not have strong gradients , and therefore taking a long examination time . with a long examination time , there will be an increase in number of heart beats causing motion artefact
旧式的mri ，由于梯度磁场不够强而未能达致要求，检查心脏需时较久，而多次的心脏跳动容易造成活动伪影，大大降低旧式的mri检查心脏的准确性。 |
| 9. | If we want to compose in a larger area a uni - gradient magnetic field , the device will be too complicated and unfit for move . it will restrict the application of hore component in displacement measuring . in order to change this situation , in this dissertation , a kind of auto - tracking measuring system is introduced
若能在简单磁场的条件下，通过自动跟随系统驱动霍尔元件跟随测量移动物体的位移，使霍尔元件尽可能地保持在均匀梯度磁场内，就可以在很大程度上增加测量范围。 |
