This hole is also a powerful oxidiser.
这个孔也是一种强大的氧化剂。
This will allow the rocket's oxidiser tank to expand when it is full.
这使得飞船的氧化罐在满载时产生膨胀。
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。
Solid-fuel rockets, in which the fuel and oxidiser are pre-mixed into a stable, solid propellant and then packed inside the case of the rocket, are simpler, lighter and relatively safer.
固体燃料火箭发动机的构造更简单、分量更轻，而且相对更安全。 在固体燃料火箭发动机里，燃料和氧化剂被预先混合成稳定的液态推进剂，然后被塞满火箭发动机的燃料箱里。
Left to themselves they would recombine, producing no net change, but some of the hydrogen leaks out of the atmosphere into space, leaving oxygen—the paradigmatical oxidiser—behind.
氢和氧再次结合成水，过程没有任何变化，不过一些氢会逃离火星大气层进入太空，只留下典型的氧。
