瓶颈技术 meaning in English

bottle neck technique

This program is launched to solve a fundamental issue existed : the direct factor influencing the optical transmission - variation of refraction index of the media in flow - field , in other words , to use ground simulation equipment or facilities to investigate the ao effects when qualitatively visualizing and quantitatively measuring the interaction of high - temperature , turbulent or shock wave flow - field with optical beam propagating through them , so that technology support can be provided for the high - speed interceptor development
本项目就是针对这一瓶颈技术存在的基础性问题：流场介质折射率变化是影响光学传输最直接的因素，即针对光线穿过高温和湍流、激波等复杂流场作定性显示和定量测量问题而开展的气动光学效应地面模拟测试研究工作，为高速拦截弹的发展提供技术基础。
