| 1 | ELASTIC-PLASTIC FINITE ELEMENT ANALYSIS OF THREE-DIMENSIONAL CONTACT-IMPACT AT RAIL JOINT显示文摘Using the finite element code ANSYS/LS-DYNA, a dynamic finite element model with an elastic-linear-kinematic-hardening plastic material is established to analyze elastic-plastic stresses in the railhead in the impact process of wheel and rail occurring at the gap of rail joint. The model is based on the discrete elastic support condition of the rails, which is suitable for the actual situation of wheeL/track rolling contact. In the analysis the influences of axle load, yield stress and tangent modulus of rail material on the stresses and strains are investigated in detail. The distribution of stresses and strains in the jointed railhead are given. It is found that the axle load, yield stress and tangent modulus of rail material greatly affect the stresses and strains in the railhead during impacting. The study provides a reliable method and useful datum for the further research on fatigue and wear of railhead and improving the rail joint mode. | Wen ZefengJin XuesongZhang WeihuaNational Traction Power Laboratory,Southwest Jiaotong University,Chengdu 610031, China | 2003 | Chinese Journal of Mechanical Engineering2003，16，4： | 11 |

| 8 | White Light Emission Characteristics of Tb3+/Sm3+Co-Doped Glass Ceramics Containing YPO4 Nanocrystals显示文摘The Tb^(3+)/Sm^(3+) single-doped and co-doped glasses and glass ceramics containing YPO_4 nanocrystals have been synthesized by melt quenching method. The structural and luminescent properties of these glass specimens were investigated. Under 375 nm wavelength excitation, the emission spectra combined with blue, green and red bands were observed, which achieved the white light emission. Moreover, the energy transfer between Tb^(3+) and Sm^(3+)ions was validated by decay lifetime measurement and energy level diagram.The color coordinates(x = 0.333, y = 0.333), correlated color temperature(5595 K) and the color rendering index(Ra = 80.5) indicated that the glass ceramics were considered to be good lighting source. Hence,the YPO_(4-) based Tb^(3+)/Sm^(3+) co-doped glass ceramics can act as potential matrix materials for white lightemitting diodes under ultraviolet excitation. | Zhixiong Zhang Yuepin Zhang Cheng Wang Zhigang Feng Weihuan Zhang Haiping Xia | 2017 | Journal of Materials Science & Technology2017，33，5： | 2 |

| 10 | Linking microbial carbon pump capacity and efficacy to soil organic carbon storage and stability under heavy metal pollution显示文摘Heavy metal pollution can lead to a great loss of soil organic carbon(SOC).However,the microbial mechanisms that link heavy metal pollution to SOC remain poorly understood.Here,we investigated five apple-orchard soils at different distances from a Pb-Zn smelter.After assessing the heavy metal pollution level based on Grade Ⅱ of the national soil environmental quality standard(China),we found SOC stocks and microbial carbon pump(MCP)capacity(i.e.,microbial residue carbon)under medium and heavy pollution levels were significantly lower than those under safe,cordon and light pollution levels.The structural equation model showed causality in the SOC variations linked to pollution level through MCP capacity,which could contribute 77.8% of the variance in SOC storage.This verified MCP capacity can serve as a key parameter for evaluation of SOC storage under heavy metal pollution.Soil MCP efficacy,i.e.,the proportion of microbial residue carbon to SOC,also decreased under medium and heavy pollution.This suggested that,with a heavier pollution level,there was a higher rate of reduction of microbial residue carbon in soil than the rate of reduction of SOC.As MCP efficacy can be a useful assessment of SOC stability,the significantly positive relationship between MCP efficacy and clay content in correlation analysis implied that lower MCP efficacy was correlated with SOC stability under the heavier pollution level.Our study provides valuable insights to identify the mechanisms of microbially mediated C transformation processes that are influenced by heavy metal pollution in agroecosystems. | Xiao Liu Xia Xu Tian Ma Shiwei Zhou Xiaoli Bi Hongbo He Xudong Zhang Weihuan Li | 2023 | Soil Ecology Letters2023，5，2： | 1 |
