| 1 | Application analysis of empirical mode decomposition and phase space reconstruction in dam time-varying characteristic显示文摘In view of some courses of the time-varying characteristics processing in the analysis of dam deformation,the paper proposes a new method to analyze the dam time-varying characteristic based on the empirical mode decomposition and phase space reconstruction theory.First of all,to reduce the influences on the traditional statistical model from human factors and assure the analysis accuracy,response variables of the time-varying characteristic are obtained by the way of the empirical mode decomposition;and then,a phase plane of those variables is reconstructed to investigate their processing rules.These methods have already been applied to an actual project and the results showed that data interpretation with the assists of empirical mode decomposition and phase space reconstruction is effective in analyzing the perturbations of response variables,explicit in reflecting the entire development process,and valid for obtaining the evolution rules of the time-varying characteristic.This methodology is a powerful technical support for people to further master the rules of dam operation. | ZHANG ZhiJun1,2,3,GU ChongShi1,2,BAO TengFei1,2,ZHANG Lan1,2 & YU Hong1,2 1 State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering,Hohai University,Nanjing 210098,China 2 National Engineering Research Center of Water Resources Efficient Utilization and Engineering Safety,Hohai University,Nanjing 210098,China 3 Department of Civil,Environmental and Geomatic Engineering,Swiss Federal Institute of Technology,Zurich 8093,Switzerland | 2010 | Science China(Technological Sciences)2010，53，6： | 4 |
| 2 | Amphiphilic dendronized homopolymers显示文摘A series of second generation of amphiphilic dendronized homopolymers are efficiently synthesized,and their thermoresponsiveness in aqueous solutions and secondary structures in methanol solutions are described.These polymers are constructed in each repeat unit with various generations of hydrophobic 4-aminoproline and hydrophilic oligoethylene glycol (OEG)-based dendrons,and their over-all hydrophilicity is tuned by varying these dendron generations.Polymers with or without the first generation of proline dendron show good water solubility at room temperature,but exhibit typical thermoresponsive behaviors at elevated temperatures as characterized by turbidity measurements using UV-vis spectroscopy,while the polymer with the secondary generation of proline dendron is not soluble in water.All polymers show ordered secondary structures as evidenced by the optical rotation and circular dichroism experiments.Finally,assembly of these amphiphilic homopolymers into porous films via breath figure (BF) technique is described,and polymer structures are found to show significant influence on the morphology of porous film. | LI Wen 1 & ZHANG AFang 1,2 1 Institute of Polymers,Department of Materials,ETH Zurich,Wolfgang-Pauli-Str.10,8093 Zurich,Switzerland 2 Department of Polymer Materials,College of Materials Science and Engineering,Shanghai University,Shanghai 201800,China | 2010 | Science China Chemistry2010，53，12： | 2 |

| 17 | 基于知识的专题制图系统——另一种途径显示文摘随着各个领域的基于知识系统的发展,大量专题制图设计问题有希望得到解决。当数据输入和用户要求格式化时,系统可在没有任何干预的情况下通过规则库指导完成全部必要的步骤。这样的一种方法将完全同交互式设计方式形成对比,而后一种方式完全是在有经验的制图员的操作控制之下进行的。考虑到问题的复杂性,采用规则引导和规则支持是必要的。规则也许有助于利用复杂相同步骤来代替通过全面而巨大的专家系统寻求解决方法的方式,但这似乎不现实。因为大量专题制图比这个目的复杂得多。本文提出的方案是与交互式模式并驾齐驱的逐渐形成的专家模型,并且对原型中几个部分的设计结构作了解释和阐述。 | E.Hutzler E.Spiess(Zurich cH) 童扬芬 | 1994 | 黑龙江测绘1994，，3： | 1 |
