Ball-disk rotor gyroscope adaptive quick-start technique
《Frontiers of Information Technology & Electronic Engineering》2017年第9期1430-1436,共7页Xiao-wei LIU Rui WENG Hai LI Hai-feng ZHANG 
Project supported by the National Basic Research Program of China (No. 2012CB934104), the National Natural Science Foundation of China (No. 61474034), the Natural Science Foundation of Heilongjiang Province of China (No. F201418), and the Fundamental Research Funds for the Central Universities, China (Nos. HIT.NSRIF. 2014040 and HIT.NSRIF.2013040)
Rotating speed is a critical parameter affecting the performance of rotor gyroscopes. Rotor gyroscopes must operate at the rated rotating speed. To shorten the start time of the ball-disk rotor gyroscope, this paper p...

Study of the efficiency of event start time determination at BESⅢ
《Chinese Physics C》2014年第1期61-64,共4页管颖慧 吕晓睿 郑阳恒 王贻芳 
Supported by Ministry of Science and Technology of China(2009CB825200);Joint Funds of National Natural Science Foundation of China(11079008);Natural Science Foundation of China(11275266);SRF for ROCS of SEM
A method to estimate the efficiency of event start time determination at BESIII is developed. This method estimates the efficiency at the event level by combining the efficiencies of various tracks (e, μ, π, K, p, ...

Predicting the start and maximum amplitude of solar cycle 24 using similar phases and a cycle grouping被引量:5
《Chinese Journal of Astronomy and Astrophysics》2009年第2期133-136,共4页Jia-Long Wang Wei-Guo Zong Gui-Ming Le Hai-Juan Zhao Yun-Qiu Tang Yang Zhang 
Supported by the National Natural Science Foundation of China;supported by NSFC through grants 10673017 and 10733020;National Basic Research Program of China through grant 2006CB806307.
We find that the solar cycles 9, 11, and 20 are similar to cycle 23 in their respective descending phases. Using this similarity and the observed data of smoothed monthly mean sunspot numbers (SMSNs) available for t...
