The dome should have excellent properties in optical  mechanical and chemical characteristics. A design of dome on supersonic mode is described according to tactical guide line of a missile. The dome made of quartz which is about 8mm thick and 141mm in window diameter. To check up the reliability of the dome  a reasonable finite element model (FEM) of dome is established  and a thermal-mechanical Analysis to the dome by finite element software NASTRAN has carried on  through these can obtained the distribution of temperature field and stress field when the speed is 2.3Ma. The results indicated that the stress was concentrated in the joint of the dome end and the Missile Section  and the maximum stress was 16.4Mpa. The stress of other nodes was smaller than the allowable stress of quartz glass. Reference to the results of the analysis  a lightweight revision to the dome structural dimension and a new method of dome fixing have put forward  which can reduce the stress concentration. 2009 SPIE.   Design of the infrared dual-band athermalized optical system based on HDE (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Advances in Infrared Imaging and Applications, June 17, 2009 - June 19, 2009, Beijing, China 作者:  Zhang L.;  Sun Q.;  Wang H.;  Wang H.;  Wang H. 收藏  |  浏览/下载：97/0  |  提交时间：2013/03/25 A dual-band infrared optical system adopting an uncooled LW infrared detector and a cooled MW infrared detector is designed and manufactured  while in the LW IR band the F/# is 1 and the focal length is 114 mm  based on the athermal ability and special diffractive properties of harmonic diffractive elements. The design shows in the MW IR band the F/# is 2 and the focal length is 72 mm  for the temperature range -40 70 the MTF value is over 0.5 at 10 lp/mm. Finite element method is applied to the opto-mechanic structure of the system for thermal analysis  for the temperature range -40C 70C the MTF value is over 0.4 at 20 lp/mm  which confirms the imaging ability of the system in a wide temperature range. 2009 SPIE.   THE INFLUENCES OF TEMPERATURE AND CHAIN-CHAIN INTERACTION ON FEATURES OF SOLITONS EXCITED IN alpha-HELIX PROTEIN MOLECULES WITH THREE CHANNELS 期刊论文  OAI收割 International Journal of Modern Physics B, 2009, 卷号: 23, 期号: 10, 页码: 2303-2322 X.
