Now, I have hundreds of liters of unused hydrazine at the MDV.

现在，飞行器中有好几百升没用过的。

If I run the hydrazine over an iridium catalyst, it'll separate into N2 and H2.

假如我用铱催化剂分解，它将分解氮气和氢气。

This is not it though; if ammonia is present in excess in the mixture, it can also produce toxic and potentially explosive liquid hydrazine.

但这不是问题所在，如果在中过量存在，它也会产生有毒和潜在爆炸性的液体肼。

Although impure liquid hydrazine doesn't explode, it can certainly boil vigorously and spray hot and chemically toxic liquid around, which can endanger the safety of people nearby.

不纯的液肼虽然不会爆炸，但肯定会剧烈沸腾，并向周围喷出炽热的化学毒性液体，危及附近人员的安全。
