叹息过后的思索——浅析影片《一声叹息》的表层结构与深层结构

深层结构潜隐在表层结构中，并转化生成众多的表层结构。影片《一声叹息》的故事情节是从表层结构走向深层结构的过程，并在深层结构中表现出根植于一定文化中的社会心理内涵和更凝重，更具普遍性的审美意义。     

一种新型双通带频率选择表面设计

本文提出了一种可以在S/C双波段形成具有高选择性通带的新型FSS,通带中心分别为2GHz和4GHz。讨论了该双通FSS的传输带宽及稳定性问题,仿真结果表明其性能良好。该FSS能用作多频馈源反射天线的副反射器和S/C双频段集成雷达的透波罩,为实现频率复用和提高天线利用率提供了可能性。     

基于直接邻域保护嵌入的人脸识别

直接邻域保护嵌入算法（DNPE）是一种以克服小样本问题而提出的NPE扩展算法,该算法通过同时对角化的方法求解邻域保护嵌入问题,避免矩阵的奇异性.在人脸数据库ORL上的测试结果表明,该算法的识别率比PCA,PCA＋LDA,NPE等算法高.     

驳岸滑坡的分析与治理

结合某航道驳岸的滑坡情况，分析滑动产生的成因和机理，根据工程本身的各种现象，研究可能出现的滑动情况，排除了属于挡土墙本身的滑动问题，而是属于土坡稳定的问题，并根据实际情况，找出处理方法。介绍了合理拟定滑动面以及确定滑带土残余抗剪强度的方法，闸述了利用抗滑桩治理滑坡的设计方案。     

亚波长金属光栅光刻条纹分布

亚波长金属光栅表面等离激元( SPP)具有光场局域增强、异常透射等现象,被广泛用于光刻。利用FDTD Solutions软件,改变金属光栅材料、周期、厚度等因素,通过有限时域差分方法探究表面等离共振光刻条纹分布特点。仿真结果表明,亚波长金属光栅光刻条纹分布周期是光栅的周期一半,光刻条纹强度在表面等离共振波长作用下也会大于入射光强度。该研究为微纳米光学器件的设计提供了依据。     

Surface cleaning? Yes,freshly grated Agar gel,please

Polysaccharide-based rigid hydrogels are by now well-established means for delivering water or, more generally an aqueous solution, to a surface in a controllable way so as to minimize diffusion and possible side-effects on water-sensitive materials during cleaning treatments. These gels can be applied as pre-formed solid bricks on planar surfaces or brushed onto objects in a semi-solid state. In this note, a different application procedure is presented, suitable for surface cleaning treatments of sensitive painted surfaces: pre-formed rigid gels grated to tiny particles that can be brushed onto the surface. A general discussion on the strategies that can be adopted when water is required to clean a water-sensitive soiled surface is presented, then the new procedure is discussed and a representative case study is shown, supporting the procedure described.     

运动性肌肉疲劳的肌电图特征及其机制探讨

本文通过文献综述法简要总结了运动导致肌肉疲劳的表面肌电图特征,介绍了表面肌电图主要测量指标及其影响因素,同时对指标的特异性做了小结:MPF对于反映肌肉疲劳较MF更具敏感性;MPF在反映肌肉功能水平差异方面具有良好的特异性和敏感性;IEMG则是反映肌肉随时间而延长出现疲劳的1个良好指标。并对可能导致表面肌电图特征改变的机制作了探讨,最后对其应用在肌肉疲劳领域的前景进行了展望。     

递增负荷运动过程中股四头肌表面肌电图的变化

表面肌电信号的检测是一种无创电检测方法,它的检测分析对临床诊断及康复医学,运动医学等具有重要意义。肌肉疲劳产生过程中,肌电图的振幅和频谱指标均会产生相应变化,肌肉疲劳通常是指肌肉运动系统最大做功能力或最大收缩能力暂时下降。SEMG信号可以在一定程度上反映肌肉收缩功能的变化,在运动性肌肉疲劳研究中将发挥重要作用。     

Microclimate inside a semi-confined environment: Valuation of suitability for the conservation of heritage materials

The microclimatic analysis of the Petrarca's tomb in Arquà Petrarca, Padua (Italy) was performed to assess the suitability of a closed environment located outdoors respect to the conservation requirements of heritage materials. Results showed that the thermo-hygrometric conditions inside the tomb were not suitable for the conservation of organic materials, like bones and wood. The orientation (north or south) was the main responsible for the different damage features of the two sides of the wooden case housing the human remains inside the tomb. Technical solutions were finally implemented to improve the conservation conditions, thus avoiding further damage.
