Traditional Chinese theories of human nature started often in the view of ethics and accomplished with moral *** ones mostly started from pure logic and leaded to political and state *** the contrary,Marx's theory of those used historical dialectics and leaded abstract attributes of man into continually expanding social ***,human nature becomes a specific process,through which people finds general law and promotes it as the highest value *** law is whether reflects the comprehensive and free development of human,and it is regarded as the evaluation standard about the development of community.

XMM-Newton observation of the eclipsing binary Algol

Research in Astronomy and Astrophysics 2011年第4期11卷 457-470页

We present an XMM-Newton observation of the eclipsing binary Algol which contains an X-ray dark b8V primary and an X-ray bright K2IV secondary. The observation covered the optical secondary eclipse and captured an X-ray flare that was eclipsed by the b star. The XMM-Newton European Photon Imaging Camera and Reflection Grating Spectrometer spectra of Algol in its quiescent state are described by a two-temperature plasma model. The cool component has a temperature around 6.4× 106 K while that of the hot component ranges from 2 to 4.0× 107 K. Coronal abundances of C, N, O, Ne, Mg, Si and Fe were obtained for each component for both the quiescent and the flare phases, generally with upper limits for S and Ar, and upper limits for C, N, and O from the hot component. F-tests show that the abundances do not need to be different between the cool and the hot component and between the quiescent and the flare phase with the exception of Fe. Although the Fe abundance of the cool component remains constant at -0.14, the hot component shows an Fe abundance of -0.28, which increases to -0.44 during the flare. This increase is expected from the chromospheric evaporation model. The absorbing column density NH of the quiescent emission is 2.5 - 1020 cm-2, while that of the flare-only emission is significantly lower and consistent with the column density of the interstellar medium. This observation substantiates earlier suggestions of the presence of X-ray absorbing material in the Algol system.

2009 International Conference on Computational Intelligence and Natural Computing(CINC 2009)

作者： Jianfeng Xu school of Software Nanchang Univeristy Nanchang PR china Lan Liu school of Information Engineering Nanchang Univeristy Nanchang PR china

The problem of model selection for support vector machines using the RbF kernels is considered. We introduce a geometric view on maximizing kernel polarization, which intuitively shows why we choose kernel polarization as the criterion for kernel selection. After that we propose a gradient-based method for learning the width parameter of RbF kernels. This method is based on the possibility of computing the gradient of kernel polarization with respect to the width parameter. The proposed method is demonstrated with some UCI machine learning benchmark examples.

In this paper, some estimations of bounds for determinant of Hadamard product of H-matrices are given. The main result is the following: if A= (aij) and b=(bij) are nonsingular H-matrices of order n and ∏in=1, aiibii> 0, and Ak and bk, k = 1, 2,…,n, are the k× k leading principal submatrices of A and b, respectively, then where M(Ak) denotes the comparison mains of Ak.

THE RELATIONSHIP bETWEEN THE TAIWAN WARM CURRENT AND TSUSHIMA WARM CURRENT

The Taiwan Warm Current （TWC） and the Tsushima Warm Current （TSWC） flow northward over the shelf in the East china Sea （ECS）, which some previous studies regard as a Taiwan-Tsushima Warm Current （TTWC） System. but the roles of the TWC and TSWC in the formation of the TTWC system have not been clarified. This article will show that the TSWC is more important in the TTWC system. Using a three-dimensional baroclinic model, we conducted several numerical experiments to reveal the dynamic relationship between the TWC and TSWC. The results show that the TWC has little effect on the TSWC, while the TSWC has a significant effect on the TWC. A source-sink driven mechanism along isobaths may be used to explain this phenomenon The perennial northward flow through the Tsushima Strait pumps the response over the northern shelf in the ECS that gives rise to the TWC. Although the TSWC is located at the ＂downstream＂ region, it could induce about 0.5 Sv to TWC in annual mean values.

The stress fields of rectangular and T shape compression dies were simulated by using three-dimensional photo-elasticity of stress freezing method. The rules of stress distribution of σx, σy, σz on the surface of rectangular and T-shaped dies were discovered, and the rules were also found inside the dies. The results indicate that the stress distribution of rectangular die is similar to that of T shape die. Obvious stress concentration in corner of die hole is observed. σz rises from die hole to periphery until it achieves maximum value then it diminishes gradually, and σz between die hole and fix diameter zone is higher than it is in other position. At the same time, the equations of stress field of extrusion dies were obtained by curved surface fitting experimental values in every observed point with multiple-unit regression analysis method and orthogonal transforms. These works can provide stress distribution model for die computer aided design and computer aided make.

The underground engineering construction is a complicated system engineering, there is greater uncertainty and security risks, carrying on the safety risk management is very necessary. Through identificating safety risk analysis of the underground projects in a risk source, combining engineering specific features, constructing the safety risk management index system, making the underground engineering safety risk management standardizated, and procedures can play a certain role in promoting. Combining monitoring information, in ArcGIS Engine flat, we use its powerful space analysis function to research safety risk management system and design the system, can realize informationization construction, providing the basis for construction decisions.
