1、So, choose as far as possible to improve the nozzle of small high cutting speed and cutting quality is useful, but the nozzle at low altitude may cause double arc phenomenon.───所以，选用尽量小的喷嘴高度对提高切割速度和切割质量都是有益的，但是，喷嘴高度过低时可能会引起双弧现象。
2、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；
3、This paper analyses reason for flame swinging in high-altitude nozzle with the ratio of large area tested under the ground atmosphere, and describes the mechanism of unsymmetrical separation.───本文分析了高空大面积比喷管在地面试验时喷管内出现火焰偏摆的原因，叙述了喷管内气流不对称分离的机理。
