摘要：The increasing accumulation of toxic mercury species in water environment has posed a serious health threat worldwide, making it inevitable to develop the versatile materials to achieve efficient prevention and remediation of mercury pollution. Guided by the solvent-assisted ligand exchange (SALE) approach, this work rationally constructed a mixed-ligand NH2-UiO-66-SH (NSU66) with hierarchical-pore structure by incorporating the thiol-rich ligands (H2DMBD) into the water-stable NH2-UiO-66 (NU66) precursor to act as a smart adsorbent equipped with sensitive detector for simultaneous sensing and removal of Hg2+. Unlike the traditional adsorbents, the as-prepared NSU66 not only exhibits a remarkable removal ability with fast capture rate (within 60.0 min), large uptake capacity (265.29 mg/g), and qualified selectivity, but also possesses satisfactory sensing capability, accompanied by low detection limit (3.50 × 10−2 µM), wide linear range (1.00–99.7 µM), high specificity, and strong anti-interference capability. The detection function plays a vital role in indicating the removal behavior and the pre-enrichment effect of adsorption process correspondingly improves the sensitivity of indicator. Notably, the sensing and trapping capabilities of NSU66 are significantly improved compared to the NU66, which stems from the delicate design of the mixed-ligand and hierarchical-pore structure. Furthermore, proven excellent stability and recyclability emphasize the feasibility of NSU66 in practical applications. These results suggest that the smart NSU66 adsorbent can serve as a favorable platform for early warning and guided removal of toxic Hg2+ in water.

摘要：Elbow draft-tubes are widely used in large- and medium-sized hydropower stations in many countries. during the application, handling the somatotype of elbow tubes has been found challenging： in order to maintain the designed shape of draft tube and to meet the requirement of construction lofting, the configuration of reinforcing bars and the fabrication of templates, the geometry of elbow tubes has to be accurately calculated to draw engineering graphics. Based on the derived equations in this paper, the motion of elbow tube curve envelope is simulated by using computers, which shows directly the smoothness of the curve and provides dynamic simulation for the study and optimization of the design and construction of elbow draft tubes, along with the front view and bottom view.

摘要：Because of good quality of compressive resistance, the hyperbolic arch dam is being increasingly applied to engineering projects. In order to satisfy the needs of compressive resistance under the conditions of high water pressure, a stress analysis is required for the dam. during the stress analysis process however, due to the complexity of the three-dimensional modeling, it is very hard to form a model. Therefore, the stress analysis process is a barrier for the arch dam. In this article, based on the research of the new line-type arch dam, a mathematical model in different degree of convexity conditions of the dam is established; using the C ＋ ＋ language program, a computer three-dimensional model simulation is realized on AutoCAD. The accurate three-dimensional model is providing a finite element optimization design of the involute hyperbolic arch dam for the next step.

The introduction of a new method in how to divide transverse joint in arch dam will be given and the further research of its calculation has been done. The C＋＋ is used in electronic procedure and the 3D simulation has been finished with AutoCAD, which will provide the object model for computer simulation of the arch dam and the division of finite element mesh. Meanwhile, this method in dividing the transverse joint in arch dam also can be taken as the calculated basis for the design and calculation of arch dam, construction lofting and the calculation of the work amount.

摘要：《天鹅湖》是古典芭蕾舞剧的巅峰之作,在19世纪末的古典芭蕾艺术史上大放异彩,与之一同被载入史册的还有俄罗斯乐坛最伟大的音乐家柴可夫斯基。在这部舞剧中,柴可夫斯基完成了对芭蕾音乐的变革,把芭蕾音乐提高到了交响化、戏剧化的水平,使之成为芭蕾舞发展史上一部里程碑式的作品。如果说《天鹅湖》创造了古典芭蕾的艺术巅峰,那么20世纪初,古典芭蕾在俄国日暮西山时,一群不满现状的艺术精英们发起了一场芭蕾变革运动,开创了早期现代芭蕾的崭新时代,《春之祭》便是其中的代表之作。本文通过芭蕾舞剧《天鹅湖》和《春之祭》中音乐形态的对比,梳理芭蕾舞剧音乐的转变、影响和突破。

摘要：雕塑与建筑都是三维的、空间的、实体的造型艺术,从雕塑艺术的角度看建筑形体塑造,从与建筑相邻近的艺术语言中寻求新的突破点,从建筑构成元素的表观上挖掘建筑的形体语言,使设计中建筑与雕塑艺术语言充分的融合,是现代建筑设计中造型语言雕塑化应用的最有效的方式。论文介绍了建筑与雕塑的造型语言,分析了雕塑造型语言在现代建筑设计中的应用,希望能为现代建筑设计提供新的思路参考。
