1Tectonic evolution of the Dabieshan orogen: In the view from polyphase deformation of the Beihuaiyang metamorphic zone显示文摘The Beihuaiyang metamorphic zone was formed by the Early Mesozoic collision of the North and South China Blocks. It consisted of the Foziling and Luzhenguan complexes and was thought to have never afforded a deep subduction. A similar feature of the deformation in the Dabieshan UHP metamorphic rocks implies that these different tectonic units share the same geodynamic background. The early stage of deformation can be preserved on account of their relatively shallower subduction than that for UHP rocks. On the basis of an analysis of the geo- logical structure and geochronological results, five deformational stages have been recognized: a D1-Early compressional deformation which represents the continental subduction; a D2-Early exhumation deformation producing a syn-convergence exhumation; a D3-Main deformation, represented by an exhumation deformation with Late Triassic age; a D4-Doming and its margin extensional gravity collapse deformation and finally a D5-regional extensional deformation of Cretaceous that was mostly introduced by the migmatization and plutonism.LIN Wei1, 2, Faure Michel3, WANG Qingchen1 & Arnaud Nicolas4 1.

2GLOBAL SOLUTIONS FOR SOME OLDROYD MODELS OF NON-NEWTONIAN FLOWS显示文摘The authors consider here some Oldroyd models of non-Newtonian flows consisting of a strong coupling between incompressible Navier-Stokes equations and some transport equations. It is proved that there exist global weak solutions for general initial conditions. The existence proof relies upon showing the propagation in time of the compactness of solutions.P. L.

3SHRIMP Dating and Recrystallization of Metamorphic Zircons from a Granitic Gneiss in the Sulu UHP Terrane显示文摘An unusual zircon SHRIMP dating result of a granitic gneiss from the Qinglongshan eclogite-gneiss roadcut section is presented in this paper. The very peculiar and complicated internal structures, as well as the very low Th/U ratios (0.01-0.08) of the zircons indicate that they were formed by metamorphic recrystallization. Strongly in contrast with previously published zircon U-Pb ages of the Dabie-Sulu UHP metamorphic rocks where protolith ages of 600-800 Ma are commonly recorded, only metamorphic age of 218+5 Ma, defined by 18 analytical spots either in rim or in core of zircons, are recorded in this granitic gneiss. This age represents the time of the complete metamorphic recrystallization overprint on primary magmatic zircons. The recrystallization was derived by the UHP metamorphism,and was strengthened by the early stage of retrograde metamorphic fluid activity.LI HongyanInstitute of Mineral Resources, Chinese Academy of Geological Sciences, Beijing 100037 Geosciences Rennes, Universite de Rennes 1, 35042 Rennes Cedex, France 2004Acta Geologica Sinica(English Edition)2004,78,1:9
4COHERENT, REGULAR AND SIMPLE SYSTEMS IN ZERO DECOMPOSITIONS OF PARTIAL DIFFERENTIAL SYSTEMS显示文摘This paper studies triangular differential systems arising from various decompositions of partial differential polynomial systems. In theoretical aspects, we emphasizeon translating differential problems into purely algebraic ones. Rosenfeld’s lemma is extended to a more general setting; relations between passivity and coherence are clarified;regular systems and simple systems are generalized and proposed, respectively. In algorithmic aspects, we review the Ritt-Wu and Seidenberg algorithms, and outline a methodfor decomposing a differential polynomial system into simple ones. Some applications arealso discussed.LI Ziming(Institute Of Algorithms and Scientific Computing, German National Research Centerfor Information Technology, D-52754 Sankt Augustin, Germany)WANG Dongming(LEIBNIZ-IMAG, 46, Avenue Felix Viallet,38031 Grenoble Cedex, France) 1999Systems Science and Mathematical Sciences1999,12,S1:7
5Quantum phase transition and entanglement in Li atom system显示文摘By use of the exact diagonalization method, the quantum phase transition and en- tanglement in a 6-Li atom system are studied. It is found that entanglement appears before the quantum phase transition and disappears after it in this exactly solvable quantum system. The present results show that the von Neumann entropy, as a measure of entanglement, may reveal the quantum phase transition in this model.SI LiMing1 & HOU JiXuan2 1 Department of Electronic Engineering, School of Information Science and Technology, Beijing Institute of Technology, Beijing 100081, China 2 Laboratoire de Chimie, UMR 5182 CNRS, Ecole Normale Supérieure de Lyon, 46, Allée d’Italie, F-69364 Lyon Cedex 07, France 2008Science China(Physics,Mechanics & Astronomy)2008,51,11:6

7Geographic Distribution of Mating Types in Magnaporthe grisea and the Relationship Between Fertile Isolates in China显示文摘377 isolates of Magnaporthe grisea were collected from 17 provinces in China and their geographic distribution of mating types and their fertility was tested with four standard isolates, KA3 and TH12 (Mat1.1) and Guy11 and TH16 (Mat1.2) provided by CIRAD. 73 fertile isolates were tested with SCAR markers of 13 pairs of primers. Preliminary results showed that the geographic distribution of M. grisea existed among isolates collected from the same location as well as different locations and the genetic relationship between fertile isolates of the fungus in China. The existence of sexual reproduction of M. grisea was explored in the field as well.SHEN Ying, Notteghem Jean Loup., Milazzo Joelle., YUAN Xiao-ping, Adreit Henry, ZHAO Xin-hua, WANG Yan-li and Tharreau Didier.(China National Rice Research Institute, Hangzhou 310006, P.

8Comparative Proteomic Analysis of B. henselae Houston and B. henselae Marseille by Two-dimensional Gel Electrophoresis显示文摘Objective To compare the protein difference between B. henselae Houston and B. henselae Marseille by two-dimensional gel electrophoresis. Method Protein samples were prepared by vorterx, ultrasonic treatment, and centrifugation. Protein concentrations were determined by Bradford method. Protein difference was compared by the first IEF and the second SDS-polyacrylamide gel electrophoresis. Results Protein concentrations in samples of Bartonella henselae Houston and Bartonella henselae Marseille were 2.117 μg/μL and 2.200 μg/μL respectively. Sample protein of 40 μg for IPG strips loading was perfect. The results of 2-DE in pH 4 to 7 IPG strips showed that the total protein spots of Bartonella henselae Houston and Bartonella henselae Marseille were 375 and 379 respectively, 95% of the spots were the same between the two strains of Bartonella henselae. Conclusion The procedure of 2-DE may prove successful for the proteomic analysis of Bartonella henselae. Bartonella henselae Houston and Bartonella henselae Marseille are different genotypes.SU-QING ZHAO*,# , YAN-FEI CAI?, AND ZHEN-YU ZHU,1 *Unite des Rickettsies, Faculte de Medecine, Universite de la Mediterranee, 13385 Marseille Cedex 05, France #Faculty of Chemical Engineering and Light Industry, Guangdong University of Technology, Guangzhou 510090, Guangdong, China ?College of Resource and Environment, South China Agriculture University, Guangzhou 510642, Guangdong, China Department of Biochemistry, Zhongshan Medical College, Sun Yat-Sen University, Guangzhou 510080, Guangdong, China 2005Biomedical and Environmental Sciences2005,18,5:3
9Distortion control of conjugacies between quadratic polynomials显示文摘We use a new type of distortion control of univalent functions to give an alternative proof of Douady-Hubbard’s ray-landing theorem for quadratic Misiurewicz polynomials.

10Weld Models Incorporating the HAZ Phase Transformation Effects, Comparison between Experimental and Numerical Results显示文摘Numerical simulations of a representative test of welding process are presented in this paper. A French vessel steel, which involves metallurgical phase transformations in solid state is considered in this work. The aim is to validate the thermal-metallurgical-mechanical models taking into account the metallurgical transformations in the finite element codes Sysweld (Framasoft) and Code Aster (EDF). The test is performed on a thin disc submitted to a thermal cycle loading by means of a CO2 laser beam, which leads to metallurgical phase transformations. The thermal, metallurgical and mechanical numerical results have been compared to the experimental results (temperatures, sizes of transformed zones, displacements and residual stresses and strains). The main objective of the numerical analysis is to have some results which enable to give some indications on the ability of the numerical codes to describe the observed phenomena. For that, it is necessary to simulate accurately the thermo-metallurgical history. The comparison of experimental results with the numerical ones leads to some interesting orientations related to the capacities of the considered models to describe the observed phenomena.V.

19The comparison study of diagnostics of light filaments in air显示文摘Long plasma channels in air induced by femtosecond laser pulses are inves-tigated using three different methods, including the cross-section imaging, resistivity measuring and acoustic diagnostics. These methods are based on different properties of the light filaments. A comparison of the three diagnostics shows that the imaging method is the most precise one in studying the filaments distribution and evolution, that the sono-graphic method is the most convenient approach to detecting long plasma channels by detecting the acoustic wave generation, and that the resistivity measurement can only be applied for giving a rough estimate. The diagnostics of filaments allow us to choose ap-propriate detecting methods and provide further insight into the dynamic evolution of the light filaments in air.HAO Zuoqiang1, ZHANG Jie1, YU Jin2, ZHENG Zhiyuan1, YUAN Xiaohui1,3, ZHANG Zhe1, LI Yutong1, WANG Zhaohua1, LING Weijun1 & WEI Zhiyi11.

20Numerical Study of the Plastic Behaviour of a Low Alloy Steel during Phase Transformation显示文摘Phase transformations in steels play a major role on the generation of residual stresses and distortions during thermal processes such as welding and heat treatments. In this paper, we focus on the influence of phase transformations on the plastic behaviour of a low-alloy steel. It is now well known that the plastic strain rate can then be decomposed as the sum of two terms. The first one corresponds to classical plasticity while the second one is due to the evolution of the transformation and is usually referred to as corresponding to transformation induced plasticity. A theoretical approach of the problem has been achieved ([1][2][3]] and a macroscopic model has been proposed in the case of ideal-plastic phases. The theoretical approach has been assessed and completed using micromechanical numerical simulations but these were based on rather coarse 3D meshes due to limited computer capabilities in the 80’s. This paper presents new finite element micromechanical calculations using refined meshes to analyse the classical plastic behaviour and transformation induced plasticity. The results of the computations are discussed and compared with the calculations initially performed. Finally improvements of the macroscopic model are proposed.J.Devaux, J.B. Leblond , J.M.
