We have synthesized SiO2-main chain acrylate material successfully. First, the surface of SiO2 nanoparticle was modified with MPS (3-Methacryloxypropyl Trimethoxy Silane). Then TEGDA (Tetraethylene glycol diacrylate) was added to control the amount of organic-inorganic ratio(10-60wt%).

The traditional methods of testing the degree of compaction only test several points,and these points can hardly represent all the area which had been compacted. So it is essential to develop a speediness,undestructive,quantificational instrument for the measurement of the degree of compaction.

传统的压实质量检测方法是用人工抽样检测来推测所有的压实区域，其结果误差较大，易造成漏检，因此研制开发一种快速、无损、定量的压实度检测仪器迫在眉睫。

Results indicate:(1) The newly developed simulation technology can form fairly average and easily controllable back pressure downstream the inlet, so it can he used to investigate the back pressure characteristics of hypersonic inlets.(2) By regulating the valve of injection pipe, the simulation technology can realize the switch of hypersonic inlet started state and unstarted state in about 8 milliseconds, so it is suitable to investigate the starting/unstarting/resarting problem of hypersonic inlets.

结果表明：(1)所提出的凹腔喷流技术可在进气道下游形成较为均匀的、可控的背压环境，因此可用于进气道的反压特性研究；(2)适当调节凹腔的喷流总压，并在实验中实时控制阀门的开度，凹腔喷流技术能够在较短的风洞实验时间内（约8s）实现进气道起动、不起动、再起动流态之间的切换，因此可用于进气道的不起动／再起动特性研究。
