| 1 | Limit analysis on seismic stability of anisotropic and nonhomogeneous slopes with anti-slide piles显示文摘This study employs the limit analysis method to evaluate the seismic stability of anisotropic and nonhomogeneous slopes stabilized with anti-slide piles. The pseudo-static approach is used to simplify the earthquake load. The yield seismic acceleration factor is obtained from the optimization procedure and the results are verified with the published data. Then, the seismically-unstable slope is reinforced with anti-slide piles, and the seismic stability of the reinforced slope is explored. The results show that the anisotropy and nonhomogeneity of soils have significant effects on the stabilizing force required from the anti-slide piles and the optimal location of the pile is near the toe of the slope. | GONG WeiBing LI JingPei LI Lin | 2018 | Science China(Technological Sciences)2018，61，1： | 7 |
| 2 | High efficiency all-dielectric pixelated metasurface for near-infrared full-Stokes polarization detection显示文摘Pixelated metasurfaces integrating both the functions of linear polarization and circular polarization filters on a single platform can achieve full-Stokes polarization detection.At present,the pixelated full-Stokes metasurfaces mainly face the following problems:low transmission,low circular dichroism(CD)of circular polarization filters,and high requirements in fabrication and integration.Herein,we propose high performance ultracompact all-dielectric pixelated full-Stokes metasurfaces in the near-infrared band based on silicon-on-insulator,which is compatible with the available semiconductor industry technologies.Circular polarization filters with high CD are achieved by using simple two-dimensional chiral structures,which can be easily integrated with the linear polarization filters on a single chip.In addition,the dielectric materials have higher transmission than metal materials with intrinsic absorption.We experimentally demonstrated the circular polarization filter with maximum CD up to 70%at a wavelength of 1.6μm and average transmission efficiency above 80%from 1.48μm to 1.6μm.Therefore,our design is highly desirable for many applications,such as target detection,clinical diagnosis,and polarimetric imaging and sensing. | Chong Zhang Jingpei Hu Yangeng Dong Aijun Zeng Huijie Huang Chinhua Wang | 2021 | Photonics Research2021，9，4： | 6 |

| 4 | Influence of Different Al Contents on Microstructure, Tensile and Wear Properties of Zn-based Alloy显示文摘The influence of different Al contents on the microstructure, hardness, tensile and wear behavior of Zn-based alloys was investigated in the present study. The test results show that alloy with 27% Al content shows the higher ultimate strength and elongation percent at room and elevated temperatures. It also exhibits the higher wear resistance at all loads in view of the higher tightness of Zn-27Al alloy. Increasing Al content from 33% to 48% results in improvement of ultimate strength and elongation percent at room and elevated temperatures. However, the ultimate strength and elongation percent of the ZA48 alloy are still lower than that of Zn-27Al alloys. The reason can be attributed to the increasing segregation and voids with increasing Al contents. | Shuqing Yan Jingpei Xie Zhongxia Liu Wenyan Wang Aiqin Wan Jiwen Li | 2010 | Journal of Materials Science & Technology2010，26，7： | 4 |
| 5 | Trust Management Mechanism for Internet of Things显示文摘Trust management has been proven to be a useful technology for providing security service and as a consequence has been used in many applications such as P2P,Grid,ad hoc network and so on.However,few researches about trust mechanism for Internet of Things(IoT) could be found in the literature,though we argue that considerable necessity is held for applying trust mechanism to IoT.In this paper,we establish a formal trust management control mechanism based on architecture modeling of IoT.We decompose the IoT into three layers,which are sensor layer,core layer and application layer,from aspects of network composition of IoT.Each layer is controlled by trust management for special purpose:self-organized,affective routing and multi-service respectively.And the final decision-making is performed by service requester according to the collected trust information as well as requester' policy.Finally,we use a formal semantics-based and fuzzy set theory to realize all above trust mechanism,the result of which provides a general framework for the development of trust models of IoT. | GU Lize WANG Jingpei SUN Bin | 2014 | China Communications2014，11，2： | 4 |
| 6 | Modification and aging precipitation behavior of hypereutectic AI-21wt.%Si alloy treated by P+Ce combination显示文摘In the present study, the tested hypereutectic Al-21 wt.%Si alloys were prepared by modifying the melt using different proportions of P and Ce, and then applying T6 heat treatment. The modif ication effects and mechanism of P+Ce complex modif ier on the Si phase of hypereutectic Al-21 wt.%Si alloy were studied, and the aging precipitation behavior after modif ication was characterized by means of tensile strength measurement, OM, SEM and TEM analysis. The results show that the massive primary silicon phase particles are signif icantly ref ined after modif ication, while the needle-like eutectic silicon crystals become f ibrous and short. It was found that the mechanism of phosphorus modifi cation on the primary silicon can be attributed to heterogeneous nucleation of Al P, while the modification mechanism of Ce can be explained by adsorbing-twinning theory. In the aged microstructure of the modif ied hypereutectic Al-21 wt.%Si alloy, there existed some strengthening phases such as Al4Cu9, Al2 Cu, AlC u3, and Al57Mn12. The P+Ce complex modif ier not only affected the size of primary silicon and eutectic silicon, but also the aging behavior of alloys under the heat treatment process. When Al-21 wt.%Si alloy was modif ied using 0.08%wt.P + 0.6wt.% Ce, the aging precipitates were dispersed uniformly in the alloy, and its mechanical properties at room and elevated temperatures are optimized(Rm = 287.6 MPa at RT, Rm = 210 MPa at 300 ℃). | Liu Pei Wang Aiqin Xie Jingpei | 2014 | China Foundry2014，11，6： | 2 |

| 14 | Influence of titanium content on wear resistance of electrolytic low-titanium eutectic Al-Si piston alloys显示文摘The wear resistance of six kinds of the electrolytic low-titanium eutectic Al-Si piston alloys with various Ti content ranging from 0.00wt.% to 0.21wt.% has been studied. A new method of adding Ti is adopted in the electrolytic low-titanium aluminum alloy ingots. The electrolytic low-titanium eutectic Al-Si piston alloys are produced by remelting the electrolytic low-titanium aluminum alloy, crystal silicon, pure magnesium, Al-50%Cu and Al-10%Mn master alloy. The wear experiments are conducted using MM200 wear testing machine under lubricating condition. The results indicate that the better wear resistance and the less weight loss are achieved in the study for the eutectic Al-Si piston alloys with 0.08wt.%–0.12wt.% Ti content. The highest ultimate tensile strength of 135.94 MPa at 300℃ and HV141.70 hardness of the alloys are obtained at 0.12wt.% and 0.08wt.% Ti content, respectively. The wear mechanism of the eutectic Al-Si piston alloys under lubricating condition is abrasive wear. | Wang Jiefang Xie Jingpei Yan Shuqing Liu Zhongxia Weng Yonggang Wang Mingxing Song Tianfu | 2008 | China Foundry2008，5，3： | 1 |
| 15 | Numerical simulation of stress field in inclusions of large rudder arm steel castings显示文摘The influence of non-metallic inclusions on quality and performance of steel depends on not only the quantity of inclusions,but also the type,shape,size,distribution,and deformation behavior. In this paper,ANSYS finite element analysis software is used to simulate the stress field of inclusions appearing in heavy rudder arm steel castings,the effects of inclusion type,shape,distribution,and various loading conditions were studied. The micromechanics of inclusions in such castings were also analyzed. Such research provides further clarification on reaction mechanism of inclusions under complex loading conditions. | Yang Dixin Xie Jingpei Zhang Kefeng Liu Zongfa Wang Aiqin Wang Wenyan | 2009 | China Foundry2009，6，3： | 1 |
