| 57. | Processes that use nitrogen as a liquid do not require the vaporizers and pressure control manifold. |
| 压力控制管控制着输入到过程的气体压力。使用液氮的过程不要求有汽化器和压力控制管。 |
|
|
| | |
| 58. | When nitrogen is converted to liquid form it becomes a cryogenic liquid. |
| 当氮转化成液态，就成为低温液体。低温液体是沸点温度一般在–238°F (–150°C)以下的液化气体。液氮的沸点是–320.5°F (–195.8°C)。 |
