The condensed phase particle size distribution affects the combustion chamber and nozzle efficiency of solid rocket motors to some extent.

凝聚相微粒尺寸分布对固体火箭发动机燃烧室效率和喷管效率有影响。

The maximum nozzle efficiency of all of plug nozzle tested here are more than 99%, some of them are nearly 100%. It has good altitude compensation.

本实验喷管设计点效率均超过99%，部分实验接近100%，高度补偿效果明显。

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;

结果表明，在高的环境压强下工作时，由塞式喷管的高度补偿能力所获得的推力是引起效率高度特性曲线非单调变化的原因；

The efficiency of his design is further improved by using the moving piston to drive water through a special steam nozzle, which increases the effectiveness of the heat transfer between the inside and outside of the reactor.
