| 1. | The choice of pumping system depends on required pumping speed, ultimate pressure attainable(in a reasonable time) .
泵系统的选择取决于所需要的抽速，能达到的极限压强（在适当的时间内）。 |
| 2. | At the appropriate pressure, the chamber is opened to a high-vacuum pumping system that continues to reduce the pressure of the process chamber .
在适当的压强下，工艺室被接通高真空泵系统抽气，以继续降低工艺室的压强。 |
