2·This saves valuable chemical propellant and extends mission lifetime.

这样既可以节省珍贵的化学燃料，又可以延长航天器的寿命。

3·Without those propellant burns, the station would eventually drop from orbit.

没有这些推进器的点燃，空间站最终会从轨道降落。

4·This should not be detrimental in any way to the performance of the propellant.

这是不应该，不利于以任何方式表现的推进剂。

5·At first, I was skeptical of the idea of ineffective ignition of the propellant.

在第一，我是持怀疑态度的想法无效点火的推进剂。

6·I will study regularly to learn more about the nature of my propellant and motor work.

9·Another major test is how to consume the least possible propellant while achieving rendezvous and docking.

如何消耗最少的推进剂完成交会对接，也是重大考验。

10·Although other electric propulsion systems exist, they require a pressurized container to store the propellant.

尽管其他电力推进系统存在，他们需要一个高压的容器来贮存推进剂。

推进剂

1·Rocket propellant has barely changed in the more than 50 years since the launch of the first artificial satellite Sputnik.

自第一颗人造卫星史泼尼克发射以来，火箭推进剂在超过50年的时间内变化不多。

2·Although other electric propulsion systems exist, they require a pressurized container to store the propellant.

尽管其他电力推进系统存在，他们需要一个高压的容器来贮存推进剂。

3·But chemical-based systems are severely limited by the fact that the vehicle mass must be made mostly of propellant, which leaves little room for the payload.

但是基于化学的推进系统被严重限制了，因为机器的质量的大部分用来给了推进剂，结果就是没怎么留下空间给装载量。

4·Russian sources said that much more experimental work and funding would be required to prove that solid propellant could be safely used for a manned landing.

俄罗斯的消息人士称，这将需要更多的试验工作以及资金来证明固体推进剂可以被安全地用于载人着陆。

5·The unmanned supply ship docked with the station Wednesday, bringing propellant, water, experiment hardware, and other items to the three crew members on board.

这艘无人资源供应船在星期三与国际空间站对接，为空间站的三名工作人员带去了推进剂、水、实验硬件和其他物品。

抛射剂

1·The pharmaceutical aerosol propellant CFC substitution has become a hot topic in international pharmaceutical field, but it has not been started in China.

药用气雾剂抛射剂CFC（氟里昂）的替代转换已成为国际药剂学研究的热点之一，我国尚未起步。

推进燃料

1·It destroyed an errant spy satellite that still had a full load of a toxic propellant called hydrazine, and was in danger of spilling it over an inhabited area when it re-entered the atmosphere.

其上仍然含有大量的被称作肼的有毒推进燃料。并且这颗卫星如果重新进入大气层，将有可能将肼扩散到居民区。

2·It will burn a mixture of solid propellant (HTPB, or hydroxyl-terminated polybutadiene) and liquid oxidiser (high-test peroxide, HTP) for 20 seconds.

它将点燃固体推进燃料(HTPB，或称羟基封端聚丁二烯)和液体氧化剂(高挥发性过氧化物，HTP)的混合物持续20秒。
