先秦两汉时期长城地带经济开发得失探究

长城地带地处农、牧业两种生产方式和文化属性相互交错、碰撞的敏感地区.考古发现揭示了内蒙古中南部长城地带春秋战国以来文化特征的演进和变化过程,反映出典型的汉式城邑及墓葬葬俗从无到有、由少到多,证明先秦两汉时期长城地带经历了历史上最重要的汉化过程,奠定了该地区统一于中原政权这一政治格局的基础.长城地带经济开发的动态过程生动阐述了因中原政府行政介入而实行强制汉化的历史进程及其正、负面影响.     

Direct observation of nodeless superconductivity and phonon modes in electron-doped copper oxide Sr1−xNdxCuO2

The microscopic understanding of high-temperature superconductivity in cuprates has been hindered by the apparent complexity of crystal structures in these materials. We used scanning tunneling microscopy and spectroscopy to study the electron-doped copper oxide compound Sr_1−xNd_xCuO₂, which has only bare cations separating the CuO₂ planes and thus the simplest infinite-layer structure of all cuprate superconductors. Tunneling conductance spectra of the major CuO₂ planes in the superconducting state revealed direct evidence for a nodeless pairing gap, regardless of variation of its magnitude with the local doping of trivalent neodymium. Furthermore, three distinct bosonic modes are observed as multiple peak-dip-hump features outside the superconducting gaps and their respective energies depend little on the spatially varying gaps. As well as the bosonic modes, with energies identical to those of the external, bending and stretching phonons of copper oxides, our findings reveal the origin of the bosonic modes in lattice vibrations rather than spin excitations.     

基于模式匹配抽取技术的网上产品情报获取

产品生命周期的逐渐缩短迫使企业关注从因特网上大量、散乱的信息中及时获取新产品信息,跟踪竞争对手研发动向。本文引入基于模式匹配的自动Web信息抽取技术,叙述抽取产品的关键信息方法,并以家用冰箱性能参数信息的自动抽取为例,分析了冰箱领域知识,进行了样本页面的分析归纳,确认了冰箱产品的多种属性及产品信息抽取的模式特征,最终获得了清晰、结构化的产品数据,形成从Web页面上抽取同类产品关键信息的整个处理流程模型,成为网络环境下情报采集与分析的新情报研究模式的一个有力探索。     

高校学生管理合同之法律分析

随着高校学生管理的民主化以及市场力量对高等教育的介入,"合同"开始被运用到我国高校学生管理之中。本文通过对学生管理合同文本的法律实证主义分析,认为目前学生管理合同具有行政合同的特征。相对于单方的校规管理方式,合同式管理是一种进步,但目前学生管理合同还存在着学生意思自治缺失以及合同合法性和合理性遭受质疑等问题。

The global significance of biodiversity science in China: an overview

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as the Qinghai-Tibetan Plateau. We review research, including species catalogues; biodiversity monitoring; the origins, distributions, maintenance and threats to biodiversity; biodiversity-related ecosystem function and services; and species and ecosystems’ responses to global change. Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China''s vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations. Based on the recent rapid progress of biodiversity research, China is well positioned to become a global leader in biodiversity research in the near future.
