1. | A piloted two-stage spaceplane using existing technology will then be seen as among the all-time best aerospace buys. |
| 而且,采用现有技术研制的由宇航员驾驶的二级太空飞机将被视为空前便宜的航天器之一。 |
2. | As a two-stage vehicle, the Saturn I had full orbital capability for a variety of payloads. |
| 作为一个两级飞行器的“土星Ⅰ”具有可将不同有效载荷送入轨道的能力。 |
3. | Like the single-stage regulator, outlet pressure from the first stage of the two-stage regulator rises as cylinder pressure decreases. |
| 同单级调整器一样,两级调整器的第一级的出口压力随钢瓶压力的降低而升高。 |
4. | The v-2 pushed the two-stage rocket to an altitude of 20 miles and then broke away. |
| V—2将第二级火箭推到20英里的高度,然后脱落。 |
5. | This is especially important in two-stage regulators that can trap high-pressure gas in the first stage. Such trapped gas can vent spontaneously at any time, releasing hazardous gas or projectiles. |
| 这对于能够把高压气体截留在第一级的两级调整器特别重要。这些截留气体随时会自发排出,释放出危险气体或抛射体。 |
