| 1 | One-pot In-situ Synthesis of Sn/Carbon-fibers Nanocomposite by Chemical Vapor Deposition and Its Li-storage Properties显示文摘Sn/carbon-fibers(CFs) nanocomposite has been prepared by chemical vapor deposition with in-situ catalytic growth of CFs.The nanocomposite has been characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FE-SEM),transmission electron microscopy(TEM) and Raman spectrum.The electrochemical performance of the nanocomposite has been investigated by galvanostatic cycling and cyclic voltammetry(CV).It has been found that a three-dimensional conductive network forms by the interconnected CFs,which offers conductive channels for the Sn nanoparticles.The nanocomposite gives a first charge capacity of 385 mAh.g-1 and exhibits an improved cycling stability than bare Sn. | J.Xie Yunxiao Zheng Shuangyu Liu Gaoshao Cao Xinbing Zhao | 2012 | Journal of Materials Science & Technology2012，28，3： | 3 |
| 2 | 双束激光焊显示文摘近年来 ,利用 2个激光束的激光焊接 ,或双束激光焊接 ,已经成为一种新兴的焊接技术。先前的研究表明 :利用双束激光工艺可以将焊瘤的起始延迟到较高速度下发生 ,并减缓冷却速率。在本研究中 ,对双束激光工艺的优点进行了详细探讨 ,并介绍了改善焊接质量的机理。 1束 6- k W CO2 激光被分离成 2个等功率的光束 ,并且双光束在焊接过程中串联排列。实验结果表明 ,双激光束显著改善了焊接质量。对于钢材而言 ,表面质量得到了改善 ,咬边、表面粗糙、焊接飞溅和缺焊等表面缺陷较少。焊缝的硬度和中心线开裂敏感性也降低。在铝质工件中 ,质量改善体现在平滑的焊缝表面、较少的气孔和咬边等焊接缺陷。用高速摄像机对工件上方焊接蒸气烟流的研究表明 :对于钢材而言 ,在常规的单束激光焊接中 ,烟流高度和大小显著变化 ,并且平均波动频率为 1 .2 k Hz。由于烟流波动和钥孔的不稳定性有关 ,不稳定的蒸气烟流表明工艺是不稳定的 ,并会导致焊缝质量较差。双束激光焊接中的蒸气烟流在某一频率范围内波动 ,但在焊接过程中烟流的大小仅轻微变化。 | J.Xie 帅平 | 2004 | 国外机车车辆工艺2004，，4： | 2 |

| 6 | Service-oriented infrastructure for flood mapping using optical and SAR satellite data显示文摘In this paper,we present the service-oriented infrastructure within the Wide Area Grid project that was carried out within the Working Group on Information Systems and Services of the Committee on Earth Observation Satellites.The developed infrastructure integrates services and computational resources of several regional and national Grid systems:Ukrainian Academician Grid(with satellite data processing Grid segment,UASpaceGrid)and Grid system at the Center on Earth Observation and Digital Earth of Chinese Academy of Sciences.The study focuses on integrating geo-information services on flood mapping provided by Ukrainian and Chinese entities to benefit from information acquired from multiple sources.We also describe services for workflow automation and management in Grid environment and provide an example of workflow automation for generating flood maps from optical and synthetic-aperture radar satellite imagery.We also discuss issues of enabling trust for the infrastructure using certificates and reputation-based model.Applications of utilizing the developed infrastructure for operational flood mapping in Ukraine and China are given as well. | N.Kussul A.Shelestov S.Skakun G.Li O.Kussul J.Xie | 2014 | International Journal of Digital Earth2014，7，10： | 0 |
| 7 | Dynamic Impact of High-Density Aluminum Foam显示文摘High-density aluminum foam can provide higher stiffness and absorb more energy during the impact Obtaining the constitutive law of such foam requires tri-axial tests with very high pressure,where difficulty may arise because the hydrostatic pressure can reach more than 30 MPa.In this paper,instead of using tri-axial tests,we proposed three easier tests-tension,compression and shear to obtain the parameters of constitutive model(the Deshpande-Fleck model).To verify the constitutive model both statically and dynamically,we carried out addi-tional triaxial tests and direct impact tests,respectively.Based on the derived model,we performed finite element simulation to study the impact response of the present foam.By dimensional analysis,we proposed an empirical equation for a non-dimensional impact time the impact time divided by the time required for plastic wave travelling from the impact surface to the bottom surface,to det ermine the deformation charac teristic of the aluminum foam after impact.For the case with t_(d)≤1,the deformation tends to exhibit a shock-type characteristic,while for the case with t_(d)>5,the deformation tends to exhibit an upsetting-type characteristic. | Q.Peng J.Xie H.S.Ma X.Ling X.Liu Y.G.Wei | 2022 | Acta Mechanica Solida Sinica2022，35，2： | 0 |
| 8 | Chaos in a Damped Power System显示文摘The analytical investigation of a damped power system has been made based on Holmes and Marsden’s theorems. The condition for the occurrence of chaotic motions in the system is that the damping factor has to possess negative values. The numerical simulation results concur very well with theoretical predictions. | J.Xie D.J.Hill | 1991 | Journal of Systems Engineering and Electronics1991，2，1： | 0 |
