燃烧室轴线 meaning in Chinese

chamber axis

Great difference in pressure for two flow made pressure wave system and it help to extend the delay time for gas in chamber , which increases combustion effusion . second , to increase combustion effusion , the inlet temperature of air and gas should be enhanced in the range of heat releasing in chemical reaction . third , the first work condition is unburned absolutely and the second work condition is burnt in shear layer of inlet and the end of down wall zone in straight segment
对于压力差很大的两股气流,所形成的压缩波系的结构可以增加燃气驻留时间,提高燃烧稳定性;为了提高扩散燃烧的效率,在保证能放热的化学反应温度范围之内,应适当提高燃气及空气的来流入口温度;燃气喷嘴应居于燃烧室轴线上,是改进超音速燃烧室结构的一种思路。
