Because of strong absorption in air  4.75keV energy microscope can just work in vacuum. Accordingly  the alignment and assemblage will be very complicated and difficult. A special multilayer method  using double periodic multilayer  was proposed to solve this problem. This multilayer has high reflectivity not only for 4.75keV X-rays but also for 8keV X-rays at the same grazing incidence angle. It means 1D-KBA microscope has the same light trace for different working energies. Therefore  we can implement the alignment and assembly of 4.75keV system by the help of 8keV X-rays. Because 8keV X-rays is very easy produced by X-ray tube and has strong transmittability in air  the alignment and assemblage process became relatively easy. By now  we have finished the alignment experiment at 8keV and obtained imaging results. The performance is about 2-3m resolution in 250m field of view. It is coincide with the calculation. 2009 SPIE.   Equivalent lenses of supersonic seeker's outflow refractive index field obtained by simulation and experiment (EI CONFERENCE) 会议论文  OAI收割 2008 International Conference on Optical Instruments and Technology: Optical Systems and Optoelectronic Instruments, November 16, 2008 - November 19, 2008, Beijing, China Qun W.; Hongguang J.; Ming X. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 In order to decrease the aerodynamic drag of supersonic image guide missile and design a non-spherical dome  the outflow field of the missile's dome is simulated using FLUENT. Based on the simulated results  the accurate density field of the outflow field at all kinds of flight conditions is obtained  and then the refractive index field of the outflow field is gotten according to the Gladstone-Dale law. The results show that the shock wave induces the heterogeneity of the refractive index field and the turbulent causes distortion. The outflow field is divided into several zones which are taken as equivalent lenses for aberration analysis. 2009 SPIE.   Unsteadiness of Shock Wave/Boundary Layer Interaction in Supersonic Cascade 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1995, 卷号: 4, 期号: 4, 页码: 243,247 Hong-Juan Wang; Shen Yu; Ke-Jun Cai 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/13 shock wave/boundary layer interaction  passive control of shock wave/boundary layer interaction (PSBLI)  A shock wave  shock oscillation   Instability theory of shock wave in a channel 期刊论文  OAI收割 Applied Mathematics and Mechanics(English Edition), 1993, 卷号: 14, 期号: 12, 页码: 1151-1162 作者:  Xu F(徐复);  Chen LS(陈乐山) 收藏  |  浏览/下载：13/0  |  提交时间：2015/09/14 shock wave, shock wave in a channel, instability theory of shock wave, shock wave stability
