The laser is driven by the digital constant current source module  and the apparatus has good human-machine interaction performance on account of set the parameters intelligently. The function such as operation mode  output power  output pulse width and pulse cycle could be easily set through the TFT touch screen. The application software could transmission the log data to the computer by the USB interface in order to check and study the records later. 2011 IEEE.   Equilibrium modeling for optimum design of operation parameters of MSW plasma gasification 会议论文  OAI收割 International Conference on Thermal Treatment Technologies and Hazardous Waste Combustors 2011, Jacksonville, FL, United states, MAY 10-13, 2011 作者:  Wang GQ(王贵全);  Li YJ(李要建);  Xu YX(徐永香);  Sheng HZ(盛宏至);  Wang GQ(王贵全) 收藏  |  浏览/下载：48/0  |  提交时间：2013/02/26 Combustion  Combustors  Hazardous materials  Heat treatment  Heating  Moisture  Moisture determination  Municipal solid waste  Plasma jets  Plasma torches  Plasmas  Synthesis gas  Technology  Waste treatment  Chinese Academy of Sciences  Concentration distributions  Constraint conditions  Duration time  Environmentally-friendly technology  Equilibrium modeling  Equilibrium models  Excess air ratios  Feeding rate  Gasification process  Gasification temperatures  Gasifiers  Heating value  High temperature  Low emission  MSW  Operating parameters  Operation parameters  Optimum designs  Plasma gasification  Process parameters  Product distributions  Simulation  State of the art  Syn-gas  Volume reductions  Working parameters   The corner detector of teeth image based on the improved SUSAN algorithm (EI CONFERENCE) 会议论文  OAI收割 3rd International Conference on BioMedical Engineering and Informatics, BMEI 2010, October 16, 2010 - October 18, 2010, Yantai, China 作者:  Yang L.;  Yang L.;  Wang X.;  Wang X.;  Wang X. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 In order to detect the corners of the teeth image  secondly  last we detected the corners of the image through the improved SUSAN corner detector algorithm.

The new method which is one of single-wavelength methods has three characteristics  introducing a method of measuring the total intensity ratio of the transmitted light to eliminate the influence of absorption by the polarizer  using circularly and homogeneously aligned LC cell (CH-LC) as a unique polarization-converting device  analyzer  using variable sector diaphragm and photodetector to detect the total intensity of transmitted light whose original polarization direction is continuously changed from 0 to arbitrary angle  CH-LC  liquid crystal display and so on. The twist angle () and optical retardation (nd) can be derived by using Jones matrix analysis and a curve fitting where and nd are fitting parameters. Experiment proved the results are accurate  the process of operation is fast  the devices are economical.   The application of Ai(OH)(3) seed in carbonization of sodium aluminate liquors 会议论文  OAI收割 Technical Session on Light Metals 2005 held at the 134th TMS Annual Meeting, San Francisco, CA, FEB 13-17, 2005 作者:  Wang, Z.;  Bi, S.
