Coolant temperature and ambient air pressure may be used to optimize cold starting and altitude performance.
冷却水温度和大气压力可用于使冷起动性能和高原性能最优化。

As the airplane climb, the ambient pressure decreases; the higher the altitude, the lower the pressure.
当飞机爬升时，环境压力减小，高度越高，压力越低。

Results show that the thrust aroused from the altitude compensation capability is the cause of the non-monotone variation of nozzle efficiency with altitude at high ambient pressure;
