摘要：背景:肩上举是一种常用练习,两种技术(头前式和头后式)可能会影响关节结构,因此需做客观分析。本研究旨在通过横向比较研究两种肩上举技术对肩部活动度和脊柱姿态的影响。方法:运用角度测量和三维生物力学测试方法研究33名受试者进行坐姿肩上举练习时肩关节的被动和主动活动幅度。结果:头前举在脊柱前凸的姿势下开始,头后举在脊柱后凸的姿势下开始。与头前举相比,头后举开始时的胸部伸展幅度更小。无论何种性别、何种肩上举技术,胸推均呈伸展状,且动作过程中的角度为12°-15°。两种肩上举技术在性别上表现出显著性差异。男性能保持正常的腰椎前凸,而女性则表现为腰椎后凸。结论:除头后式技术时男性肩关节产生外旋外,其余的肩关节动作幅度都在被动动作幅度之内。为避免可能出现的损伤,在头后式肩上举练习前应增加被动动作幅度。女性显现出更大的脊柱活动度,表明加强躯干力量有助于肩上举动作的完成。对具有正常躯干稳定性和理想肩关节动作幅度的受试者来说,无论头前式还是头后式,推举对于肩部和脊柱都最一种较为安全的练习。

摘要：新兴的量子点(QD)发光场效应晶体管(QLEFET)能够以较低成本产生高颜色纯度的发光,并且其光电特性易于调节.研究人员在设计器件结构和理解深层物理机制等方面已作了大量尝试,但由于界面处的电荷/激子损耗和QD层与相邻载流子传输层之间存在着较大的能量势垒,目前QLEFET的整体性能仍然偏低.鉴于此,本文采用一个介电层-QD-介电层的(DQD)的三明治夹层结构设计买现了外量子效率(EQE)超过20%的QLEFET.该DQD结构可以通过调节能带排列进一步调控器件中载流子行为,从而使激子复合区移动进入QD发光层.此外,通过抑制表面陷阱和界面电荷转移诱导的荧光碎灭引起的激子损耗,有效提高了激子的辐射复合.本研究提出的DQD夹层结构设计是一种改善QLEFET电致发光胜能的全新概念,也可以将其应用到其他材料体系中,促进QD在新型光电器件中的开发应用.

摘要：The paper presents a dynamic model intervened by urban design for the decision-making of land development intensity, which expresses the inherent interaction mechanism between lands based on the evaluation of land attributes and their similarity relationship. Each land unit is described with several factors according to their condition and potential for development, such as land function, accessibility, historical site control, landscape control, and so on. Then, the dynamic reference relationship between land units is established according to the similarity relationship between their factors. That means lands with similar conditions tend to have similar development intensities, which expresses the rule of the spontaneous urban development. Therefore, the development intensities of the pending lands can be calculated by the confirmed ones. Furthermore, the system can be actively intervened by adjusting the parameters according to urban design or planning intentions. And the reaction of the system offers effective support and reference for reasonable decision. The system with multiple intervention input is not only a credible tool for deriving development intensities, but also a platform to activate urban design conception. Above all, the system as a socio-technical tool integrates the optimization of form, function and environment, and embodies the principle of impersonality, justice and flexibility in the decision of land development intensity.

摘要：载体上孤立的Pd原子作为乙炔半加氢反应的催化活性位点,由于具有独特的反应性和高效的金属利用率而备受关注.特别是在金属氧化物表面的不同位点掺杂Pd单原子,可以通过调节其局部配位环境来调控其电子和催化性能.本文采用密度泛函理论计算,研究了TiO_(2)负载Pd单原子的局域配位环境对Pd_(1)/TiO_(2)催化剂上乙炔半加氢反应的活性和选择性的影响.综合考虑反应活性和选择性,发现具有负电荷Pd^(δ-)位点的Pd_(1)Ti_(3)/TiO_(2)四原子单团簇催化剂展现出优异的催化性能.此外,活性和选择性与表面性质如d-带中心指数和表面功函数等密切相关.本文为未来设计可还原氧化物载体上的高效单团簇催化剂以用于类似的多相催化反应提供了理论参考.

摘要：过去三十年间,考试影响已经被认为是考试效度验证中后果方面的重要证据,在语言测评领域引起了越来越多的关注。此方面现有研究多关注于测试对课堂内教学的影响(通常称之为"反拨效应"),而对测试在课堂之外的个体、政策及实践等社会层面的影响研究甚少。为此,本文研究了2011年至2017年间两种国家级报纸的数据,以此分析高考对于中国教育社会层面的影响。文献分析的结果显示了高考在诸多方面的巨大影响,包括考试内容、施考、利益相关方承受的压力、学校教学实践、教育政策等方面,特别是举国瞩目的现行高考改革。我们的分析显示考试内容设计需更多关注农村考生群体,考试需系统地提供更具包容性的施考程序,以及高考改革的成功需有课程及教法的配套改革支持。
