	Research of ballistic missile early warning system (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Advanced Engineering Materials and Technology, AEMT 2012, July 6, 2012 - July 8, 2012, Zhuhai, China Zhang M.-H.; Zhang Y.-Y. 收藏 \| 浏览/下载：48/0 \| 提交时间：2013/03/25 To develop a lift early warning infrared device as a part of land or boat (ship) early warning system the system has the ability to target pre-discovery and instructions invasion. Methods: In support of distant air situation alerts the enemy aircraft missiles and other long-range goals obtain the target type and preliminary judgment of grade deliver the alarm information to the command system. The infrared alarm device detects the target's own infrared radiation passively alarms the incoming targets at low altitude and low altitude remote when radar and other equipment is out of work. Results: The accuracy of entire system reached 20 according the analysis. Conclusions: The device has a full range of complex background with high sensitivity high resolution anti-jamming fast response time and other characteristics.

	Measuring instrument for radial composite deviations of high-precision master gear (EI CONFERENCE) 会议论文 OAI收割 6th International Symposium on Precision Engineering Measurements and Instrumentation, August 8, 2010 - August 11, 2010, Hangzhou, China 作者: Zhang Y.; Wang L.; Wang L.; Wang L. 收藏 \| 浏览/下载：69/0 \| 提交时间：2013/03/25 During double flank rolling composite detection the radial composite deviations of master gears has been existed and transferred to the measured gear by the primary harmonic curve. In order to improve measurement accuracy a measuring instrument is developed for radial composite deviations of high-precision master gear in the paper. This instrument uses the structure of spring-suspend swing span to overcome the shortcomings of large rotation errors low sensitivity low resolution and large measuring force appearing in the traditional combination-type gear inspection instrument. Artificial intelligence technology is used to improve the efficiency and accuracy of this instrument. The result is that the measuring apparatus is able to meet the requirement and improve efficiency through the measuring experiments on master gears of precision grade 2 with modulus 2 mm and 3 mm respectively. 2010 SPIE.
