采用文献资料、历史考证与田野调察等研究方法，对中华传统龙舟文化认同的内涵表征、现实困境与建构思路进行研究。内涵表征：历史渊源与话语叙事是传统龙舟文化认同的生成根基、象征符号与精神体认是传统龙舟文化认同的归属表征、价值共识与文化自觉是传统龙舟文化认同的生态意蕴。现实困境：社会转型中“乡土性”变迁招致传统龙舟文化认同主体的心理漠视、社会碎片化的“自我中心式”观念引致传统龙舟文化认同的层次链接断裂、竞技体育“锦标主义”的盛行导致传统龙舟文化认同的同一性基础弱化。建构思路：以道德共相导引中华传统龙舟文化认同集体记忆、以族群共相凸显中华传统龙舟文化认同辨识意蕴、以伦理共相规范中华传统龙舟文化认同禁忌规则、以审美共相强化中华传统龙舟文化认同鼓励意义。

To study the adsorption behavior of Cu^＋ in aqueous solution on semiconductor surface, the interactions of Cu^＋ and hydrated Cu^＋ cations with the clean Si（111） surface were investigated via hybrid density functional theory（B3LYP） and Moller-Plesset second-order perturbation（MP2） method. The clean Si（111） surface was described with cluster models（Si14H17, Si16H20 and Si22H21） and a four-silicon layer slab under periodic boundary conditions. Calculation results indicate that the bonding nature of adsorption of Cu^＋ on Si surface can be viewed as partial covalent as well as ionic bonding. The binding energies between hydrated Cu^＋ cations and Si（111） surface are large, suggesting a strong interaction between them. The coordination number of Cu^＋（H2O）n on Si（111） surface was found to be 4. As the number of water molecules is larger than 5, water molecules form a hydrogen bond network. In aqueous solution, Cu^＋ cations will safely attach to the clean Si（111） surface.

We theoretically investigate the spin resolved Friedel oscillation （FO） and quasiparticle interference （QPI） in graphene induced by an Anderson *** the impurity becomes magnetic,the resulted FO becomes spin dependent,which gives rise to a local magnetic moment oscillation with an envelop decaying as r-2in real space in the doping ***,at half filling,the electron density and local magnetic moment will not oscillate but decay as *** spin resolved FO has both sublattice and spin ***,the local magnetic moment decay at half filling only occurs at one sublattice of graphene,which is quite like the phenomenon observed in the STM experiment (***ález-Herrero et al.,Science 352,437 （2016）).We further give an analytic formula about such spin dependent FO based on the stationary phase ***,we study the interference of quasiparticles around the magnetic impurity by calculating the spin dependent Fourier-transformed local density of states （FT-LDOS）.Our work gives a comprehensive understanding about the local magnetic moment oscillation around an Anderson impurity on graphene.

为了提高Fe-Cr-C-B系堆焊合金的耐磨性能,在低频脉冲交流纵向磁场作用下进行明弧堆焊试验。借助X射线衍射仪（XRD）、光学显微镜（OM）、扫描电子显微镜（SEM）、洛氏硬度计和磨料磨损试验机对堆焊合金的组织和性能进行了分析检测,研究了磁场电流对堆焊合金组织和性能的影响规律。结果表明,外加磁场可以显著改善堆焊合金的显微组织和力学性能。当磁场电流为3 A时,堆焊合金的组织由马氏体、残余奥氏体、M7（C,B）3和M（23）（C,B）6组成;基体组织细化,共晶组织增多并且大部分呈断续网状形态分布,有效地抵抗了磨料的磨削作用。此时,堆焊层的耐磨性最佳,硬度最高,为56 HRC,磨损量最少,为0.3895 g。
