NOx is produced when the nitrogen from the air reacts with oxygen under highengine temperature and pressure conditions.
在高温高压下，空气与氧气反应，产生了氮氧化物。

The system uses the engine to drive a hydraulic pump that charges an accumulator to highpressure.
这种系统利用该发动机来驱动液压泵以使蓄压器充满压力达到高压。

That's one reason why gas turbines work so well in aircraft; other than taxing, landing, or taking off, the engine runs at highpressure, high power and high temperature.
