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联氨。

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.

液肼虽然会爆炸，但肯定会剧烈沸腾，并向周围喷出炽热化学毒性液体，危及附近人员安全。

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联氨，它将分解成氮气和氢气。

To adjust course and orientation, the probes are  equipped with gyroscopes for stabilization, referencing instruments and 16 hydrazine  thrusters, including 8 backups.

为调整航向和姿态，探测器用于稳定陀螺仪、参考仪器以及16个联氨推进器，其中包括8个用推进器。

Moreover, satellites carrying an energetic fuel like hydrazine must undergo special tests to be certified as safe for inclusion in a launch.

此外，携带高能燃料如联氨卫星必须通过特殊测试，以确保安全并获得发射资格。

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

但这是问题所在，如果氨在混合物中过量存在，它也会产生有毒和潜在爆炸性液体肼。
