People always eradicate and polish old wall during the reconstructing of old houses, and they often use angle grinding machine to polish old metope manually , labor intensity is very great and the wall is not even after polishing .this paper designs a metope-polishing robot, it can polish old metope automatically ,it substitutes order polishing of machine for out-of-order polishing of manpower ,so it can improve labor circumstance and prevent from polluting environment, and it can improve the efficiency remarkably and alleviate labor intensity of manpower.

在旧房改造时通常要对旧墙面进行铲除抛光，目前普遍使用角磨机进行人工打磨，其劳动强度大，打磨后的墙面不平整。本文设计出了一种墙面抛光机器人，它可全自动的实现对旧房墙面的打磨抛光，以机器的有序抛光代替人工的无序抛光，改善了劳动环境，防止了环境污染，并可大幅度提高效率，减轻人工劳动强度。

There exist cupidity modular, chaos, disorder ect. in real University management as the missing of esthetic culture. Esthetic culture is significant to University management, make the supervisor cxceed utilitarian desire, make the staff exceed the modular management, direct the supervisor creat harmonious, effective administration and rise superior to efficiency.

Mesoporous zincum sulfide is synthesized by gentle wet chemosynthesis method, with DDA as templates and Zinc acetate and TAA as precursors. The effect to the synthesis of the ratio of reactive components, the volume of pH, reactive time and reactive temperature has been dicussed systematically, and structures of the as-synthesized samples have been characterized by X-ray diffraction, N2 adsorption-desorption, scanning electron microscopy, Fourier transform-infrared spectra, UV-vis diffuse reflectance spectroscopy, transmission electron microscopy.

以十二胺为模板，醋酸锌及硫代乙酰胺为前驱体，温和湿化学法合成了硫化锌无序介孔结构，系统研究了反应物配比、pH值、反应温度、反应时间对材料合成的影响，运用X射线衍射、N2吸附-脱附、扫描电镜、红外光谱、紫外-可见吸收光谱、透射电镜等分析手段对介孔材料的结构进行了详细的表征。

The research of this paper includes three parts: the first, according to the statistical figures about the cargo transport in recent years, it analyzes cargo transport structure and the changing law and the internal reason of cargo transport. At the same time it analyzes and calculates the change of the arriving ships" structure for a systematic and full understand of the transport demands. The second, it make a scientific forecast of the port"s future cargo capacity making use of the grey forecast system, which provides scientific basis for medium-long term development plan of the ports cargo handling capacity. It also makes some analysis and research for medium-long term development future of Zhangjiagang port in use of physical unit analising technique, looks for the scattered no-order and no-system reason of medium-long term development. On the basis of summarizing their experience, the article adopts physical unit model to make a comprehensive judgement. It has distinctive opinion of value in accord with scientific principles for medium-long term development of Zhangjiagang port.

本文研究的工作主要分三个部分：第一，根据张家港近年来有关货物运输的一些统计数据，对货物运输的结构和规模演变的规律及内在原因作一剖析，同时对到港船舶的结构变化进行预测，以求对运输需求有一个系统全面的了解；第二，应用灰色预测系统对张家港港未来港口货运吞吐量进行科学预测，为张家港港货物装卸能力规划提供科学依据；应用物元分析技术对张家港港口的未来发展前景作出一定程度的分析、研究，找出张家港港口未来发展规划的零散无序、不成系统的因素，总结前人经验的基础上采用综合评判物元模型进行评判，在预测港口未来发展规划是否科学实际上具有独到见解。

The piling up, taking apart and reassembling of objects thus becomes a metaphor of entropic and evolutionary movements.

於是对物体的堆砌、拆解和重组被比喻成熵和进化（熵是指系统运行有序和无序的程度，维持一个系统的有序必然破坏另一个系统，越无序，熵量越大）。
