| 3. | Because ther is no impact force during start process , so it greatly reduces the wearness of the mechanism including pinion and rack
由于启动时无冲击，大大降低了轮条等机械磨损。 |
| 4. | 2 . the process of starding or stopping of the cage is very steady and there is no impact force applying on the mechanism . 3
2 .启制动平稳，无动击3 .启动电流小于额定电流4 .机械磨损降低。 |
| 5. | How to use and manage hydraulic oil is vital for avoiding abrasion and breakdown and for prolonging the lifetime of machines
正确使用与管理液压油对减少机械磨损和故障，延长机械寿命具有重要作用。 |
| 6. | Because there is no impact force during start process , so it greatly reduces the wearness of the mechanism including pinion and rack
4 .机械磨损降低。由于启动时无冲击，大大降低了轮条等机械磨损。 |
| 7. | On the other hand , the adjustment or tuning of controllers need to be carried out because of the mechanical wear or the variations of environment or operating mode
另外，由于机械磨损、环境工况变化的原因，控制系统的现场整定应是经常性的。 |
| 8. | High reliability : the seal contains a simple , permanent magnetic structure and a non - wearing magnetic fluid . the only parts subject to mechanical wear are self - contained ball bearings
良好可靠性：密封圈由永磁结构和稳定的磁性流体组成，所以机械磨损仅发生在轴承上。 |
| 9. | This results in the low efficiency and the short life of the equipment . and for that , it ca n ' t guarantee the reliability of the system for long term running
过去，由旋转电机驱动的物流传输系统，机械磨损和噪音较大，设备的效率不高，使用年限不长，无法保证系统长期运行的可靠性。 |
| 10. | When there is random error in input data , if position - keeping plan is applied , thrusters will change working status in high frequency that will lead to sever thrust wear and energy waste
当输入存在随机误差的情况下，采用常规的定点定位控制方法会导致推进器频繁改变状态，造成不必要的机械磨损，浪费很大的能量。 |
