| 4. | Electrohydraulic push rod drives the two - way pump to output pressure oil with rotation of motor clockwise and counter - clockwise , by control of hydraulic valve , send to the hydraulic cylinder , to achieve the reciprocating movement of the piston rod
电液推杆以电动机正反转，带动双向泵输出压力油，经液压阀控制，送至液压缸，实现活塞杆的往复运动。 |
| 5. | The reactor can be shutdown during emergency by cutting off the power supply to the control rod driving mechanism which then causes the control rods to drop down to the reactor core by gravity quickly and thereby stopping the nuclear fission immediately
在需要紧急停堆时， ?须切断控制棒驱动机械的电源，控制棒便会因地心吸力而快速下坠至反应堆堆芯，立即停止核裂变。 |
| 6. | Each control rod assembly consists of a number of absorber rods attached to a spider assembly and coupled to the control rod drive mechanism . the absorber rods are made up of neutron absorbers such as silver , indium and cadmium . hence , by adjusting the position of the control rods , the number of neutrons and thus the fission rate in the reactor can be controlled
及控制反应堆的核裂变，部份燃料组件装配有控制棒，控制棒组件由星型架及多根含银( ag ) 、铟( in )和镉( cd )的中子吸收体棒所组成，因此移动控制棒的上下位置就可以控制反应堆内中子的数目与及核裂变。 |
