1·Computational investigation of secondary flow thrust vector control technology used in a convergent-divergent nozzle;

采用六分力试验技术对某推力矢量发动机燃气舵的气动特性进行了试验研究。

2·The nozzle was entirely blackened, with the hottest region being where the throat meets the divergent section .

喷嘴是完全发黑的，与最热门的地区正在那里喉咙会见不同的区段。

3·There are particles on whole cross section of nozzle divergent section and this fact shows that there is nono particles zonein nozzle divergent section.

喷管扩张段整个截面上都有粒子分布， 说明喷管扩张段中不存在“无粒子区”；

4·The present invention belongs to a method for manufacturing oxygen-acetylene (liquefied gas) cutting nozzle and divergent cutting nozzle.

本发明属于氧-乙炔(液化气)割嘴、扩散型割嘴新的制造方法。

5·The cutting nozzle and divergent cutting nozzle produced by using said method are low in cost, high in efficiency and good in quality.

用此方法生产割嘴、扩散型割嘴成本低、效率高、质量好。

6·A new propulsion concept of 2 D C D vectoring nozzle was proposed, which had a convergent duct shaped by spheric surface and a divergent one with rectangular transverse section.

提出了一种二元收扩矢量喷管的概念，用热射流实验台对二元矢量喷管进行了过膨胀状态下的喷管模型热态实验。
