Temperature Prediction for Sun Synchronous Satellite on Orbit

Wei Chuanfeng,Li Yunze,Yuan Lingshuang,Wang Jun,Ning Xianwen

Strategic Study of Chinese Academy of Engineering 2005, Volume 7, Issue 2,   Pages 73-75

Abstract:

Temperature prediction on-line for sun synchronous satellite is very essential. In this paper, satellite's temperature is predicted on-line after the analysis to the cycles of orbital external thermal current and average temperature. Temperature distribution predicted by last two circles can be the basis on thermal fault diagnosis for satellites. Meanwhile the error accumulation can be avoided. Fly experiment data show that the method is reliable.

Possible solutions for sludge dewatering in China

Wei WANG, Yuxiang LUO, Wei QIAO,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 1,   Pages 102-107 doi: 10.1007/s11783-010-0001-z

Abstract: Traditional disposal methods used by municipal solid waste treatment facilities, such as landfills, composting, or incineration, are unsuitable for sludge disposal because of its high water content.Disposal of sludge has therefore become a major focus of current environmental protection policies.The present status of sludge treatment and disposal methodology is introduced in this paper.consumption of sludge dewatering from 80% to 50% has been a key issue for safe and economic sludge disposal
