| 3. | Their major advantages over conventional bearings results from the fact that there is no mechanical contact between rotor and stator
与传统轴承相比，其主要优点源于定子和转子之间没有接触。 |
| 4. | This article introduces one technique swayings mechanical contact whell based on hall componets to measure straight line long displacement
为此提出了一种以摆动式机械接触滚轮为基本原理，基于霍尔元件进行信号检测的直线大位移测量方法。 |
| 5. | The magnetic bearing is a novel type , high performance bearing , which suspend the rotor by magnetic force without any mechanical contact between rotor and stator
磁悬浮轴承是一种利用磁场力将转子悬浮于空中，使转子与定子之间实现无机械接触的一种新型高性能轴承。 |
| 6. | The switch is not only when switching over with production of electric arc , mechanical contact head easy to be damaged , but also it is slow to regulate , ca n ' t frequently operate , so limit the range of application of this kind of switch
这种开关不仅切换时伴有电弧的产生，机械触头容易损坏，而且调节速度慢，不能频繁操作，因此限制了这种开关的应用范围。 |
