从“体育权”英译“sports rights”可以看出我国体育学界设计的体育权概念存在权利范围过于庞大的问题。各国宪法体育权条款的英文表达式大致呈现出四种类型,其中三种有国际法渊源,体现出体育接近权、体育实践权和完整意义上的体育权三种权利理念。以此为基础,根据人们对“体育权”需要的大致流程以及每步流程在权利主体、权利性质、权利关注点及其价值取向上的各自不同,我们可以尝试构建以“体育实践权”为理念核心的中国体育权规范体系。

为探讨芦荟大黄素与α-葡萄糖苷酶的相互作用,本实验采用酶抑制动力学、紫外光谱、红外光谱、荧光光谱等多种光谱分析法研究芦荟大黄素对α-葡萄糖苷酶的抑制机理,并研究芦荟大黄素与阿卡波糖联用的协同效应。结果显示,相较于阿卡波糖,芦荟大黄素具有更好的α-葡萄糖苷酶抑制效果,属于非竞争性和反竞争性的混合型抑制剂。紫外光谱结果表明芦荟大黄素与α-葡萄糖苷酶之间通过相互作用形成了新的复合物。红外光谱中酰胺基团的特征振动结果表明随着芦荟大黄素加入,α-葡萄糖苷酶结构构象发生变化。荧光猝灭实验结果说明,芦荟大黄素是以静态猝灭的方式猝灭α-葡萄糖苷酶的内源性荧光。此外,芦荟大黄素和阿卡波糖联用对α-葡萄糖苷酶活性有一定的协同抑制效果。本研究揭示了芦荟大黄素对α-葡萄糖苷酶的抑制作用机制,为未来将芦荟大黄素作为调节人体血糖的保健食品配方提供了实验依据。

采用快速化学法合成施氏矿物(Sch)和含Cr施氏矿物(Cr-Sch),并通过批量实验法,系统研究油酸浓度和pH值对Sch转化进程及转化过程中Cr的迁移.研究表明,油酸钠能够显著抑制Sch的溶解—转化进程,油酸根与Sch溶解所释放的Fe离子结合为络合物或沉淀附着于Sch表面,抑制转化的进行;Cr(VI)的掺杂能够增强Sch的稳定性,从而进一步抑制Sch的转化速率.实验体系pH值升高有利于Sch向针铁矿的转化.此外,Sch中Cr的释放规律与Sch的溶解转化速率密切相关.在低pH值条件下,Cr持续向环境中释放;高的pH值条件下,环境中Cr的释放量极大降低,Sch中的Cr进入到次生针铁矿中.

As the highest, coldest and driest place in Antarctica, Dome A provides exceptionally good observing conditions for ground-based observations over terahertz wavebands. The 5 m Dome A Terahertz Explorer （DATES） has been proposed to explore new terahertz windows, primarily over wavelengths between 350 and 200 pm. DATE5 will be an open-air, fully-steerable telescope that can function by unmanned operation with remote control. The telescope will be able to endure the harsh polar environment, including high altitude, very low temperature and very low air pressure. The unique specifications, including high accuracies for surface shape and pointing and fully automatic year-around remote operation, along with a stringent limit on the periods of on-site assembly, testing and maintenance, bring a number of challenges to the design, construction, assembly and operation of this telescope. This paper intro- duces general concepts related to the design of the DATE5 antenna. Beginning from an overview of the environmental and operational limitations, the design specifications and requirements of the DATE5 antenna are listed. From these, major aspects on the conceptual design studies, including the antenna optics, the backup structure, the pan- els, the subreflector, the mounting and the antenna base structure, are explained. Some critical issues of performance are justified through analyses that use computational fluid dynamics, thermal analysis and de-icing studies, and the proposed approaches for test operation and on-site assembly. Based on these studies, we conclude that the specifications of the DATE5 antenna can generally be met by using enhanced technological approaches.
