Let （Mn, g） and （N^n＋1, G） be Riemannian manifolds. Let TMn and TN^n＋1 be the associated tangent bundles. Let f ：（M^n, g） → （N^＋1, G） be an isometrical immersion with g = f^＊G, F = （f, df）：（TM^n,g） → （TN^n＋1, Gs） be the isometrical immersion with g= F＊Gs where （df）x ： TxM → Tf（x）N for any x∈ M is the differential map, and Gs be the Sasaki metric on TN induced from G. This paper deals with the geometry of TM^n as a submanifold of TN^n＋1 by the moving frame method. The authors firstly study the extrinsic geometry of TMn in TN^n＋1. Then the integrability of the induced almost complex structure of TM is discussed.

MEAN-VARIANCE MODEL BASED ON FILTERS OF MINIMUM SPANNING TREE

引用

Journal of Systems Science and Systems Engineering 2011年第4期20卷 495-506页

作者： Feixue HUANG lei sun Yun WANG 1Economics School Faculty of Management and Economics Dalian University of Technology Dalian 116024 China

This study aims to reduce the statistical uncertainty of the correlation coefficient matrix in the mean-variance model of Markowitz. A filtering algorithm based on minimum spanning tree （MST） is proposed. Daily data of the 30 stocks of the Hang Seng Index （HSI） and Dow Jones Index （DJI） from 2004 to 2009 are selected as the base dataset. The proposed algorithm is compared with the Markowitz method in terms of risk, reliability, and effective size of the portfolio. Results show that （1） although the predicted risk of portfolio built with the MST is slightly higher than that of Markowitz, the realized risk of MST filtering algorithm is much smaller; and （2） the reliability and the effective size of filtering algorithm based on MST is apparently better than that of the Markowitz portfolio. Therefore, conclusion is that filtering algorithm based on MST improves the mean-variance model of Markowitz.

作者： sun lei WANG Yuan CHEN Wei State Key Laboratory of Electroanalytical Chemistry Changchun Institute of Applied Chemistry Chinese Academy of Sciences School of Chemistry and Environmental Engineering Changchun University of Science and Technology

In this work, novel CaCO3/Ag2CO3/AgI/Ag plasmonic photocatalysts were successfully synthesized by a two-step in situ ion exchange process and their photocatalytic properties were studied. The morphology, crystal structure and optical properties of the as-prepared CaCO3/Ag2CO3/AgI/Ag nanocomposites were characterized by transmission electron microscopy （TEM）, X- Ray diffraction （XRD）, and UV-vis diffuse reflectance spectroscopy. The photocatalytic activity of the obtained nanocomposites was evaluated by the photodegradation of methyl orange （MO） under visible light irradiation. It was found that the as-prepared CaCO3/Ag2CO3/AgI/Ag plasmonic photocatalyst exhibits high visible light photocatalytic activity. With an optimized composition, MO dye can be decomposed by more than 94% within 15 min under visible light irradiation. Moreover, the photocatalytic stability could be greatly improved upon the addition of Na2CO3 into the photocatalytic system. From the proposed photocatalytic mechanism, the strong surface plasmon resonance effect of Ag nanoparticles and the efficient separation of photogenerated electrons and holes can effectively enhance the photocatalytic performance of the CaCO3/Ag2COj AgI/Ag composites.

Influencing factors of disinfection byproducts formation during chloramination of Cyclops metabolite solutions

引用

Journal of Environmental Sciences 2014年第3期26卷 575-580页

作者： Xingbin sun lei sun Ying Lu Jing Zhang Kejing Wang Department of Environmental Science Northeast Forestry University

Effects of reaction time, chlorine dosage, pH and temperature on the formation of disinfection byproducts （DBPs）, were investigated during the chloramination of Cyclops metabolite solutions. The results showed that some species of DBPs like trichloromethane （TCM）, dichloroacetic acid （DCAA） and trichloroacetic acid （TCAA） could accumulate to their respective stable values with a progressive elevation in reaction time and monochloramine concentration. And 1,1,1-2-trichloropropanone （1,1,1- TCP） content decreased correspondingly with a continuous increase of reaction time. The amounts of chloral hydrate （CH）, chloropicrin （TCNM）, 1,1,1-TCP and DCAA firstly increased and then decreased with increasing monochloramine doses. Higher temperature resulted in a decrease of CH, dichloroacetonitrile （DCAN）, 1,1-dichloropropanone （1,1-DCP）, 1,1,1-TCP, DCAA and TCAA concentration, pH affected the formation of the different DBPs distinctly. TCM accumulateded with the increase of pH under 9, and DCAA, TCAA, CH and 1,1-DCP decreased continuously with increasing pH from 5 to 10, and other DBPs had the maximum concentrations at pH 6-7.
