热处理对MEH-PPV薄膜微力学行为的影响

利用纳米压痕技术研究了热处理对聚(2-甲氧基-5-(2’-乙基己基氧)-1-4-苯撑乙烯)(MEH-PPV)薄膜力学性能的影响,结果表明:随着热处理温度的提高,最大压痕深度先减小后增加,弹性模量、硬度随着热处理温度的提高而降低;另外,MEH-PPV薄膜对负载率的敏感性随热处理温度的提高而降低;同时利用高斯网络模型分析了热处理对MEH-PPV薄膜力学性能影响的原因,拓扑缠结对MEH-PPV薄膜力学性能影响是主要的,而凝聚缠结对MEH-PPV薄膜力学性能影响是次要的。

离子束溅射氟碳高分子膜的X射线能谱研究

在不同放电条件下利用离子束溅射法制备了聚酯膜基底上的氟碳高分子膜，用光电子能谱法对其结构进行了分析表征，研究发现，该条件下制备的氟碳高分子由－CF3，－CF2，－CF和－C－两个基团组成，随着施加能量的增大，富氟组分增加导致氟碳比增加，但在较高能量下这种变化趋缓，氟碳高分子在这种能量变化中逐渐向直链、饱和，较小分子量的结构转变。

Preparation and performance of novel LLTO thin film electrolytes for thin film lithium batteries

We prepared a series of lithium lanthanum titanate(LLTO) thin film electrolytes by radio frequency(RF) magnetron sputtering using LLTO targets in a N2 atmosphere.We also deposited the LLTO thin films in an Ar atmosphere under a same condition as references for comparison.The microstructure morphology and the composition of the thin films were investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS),respectively.Results show that the thin film has an amorphous structure with a uniform surface and it is free of pinholes and cracks.Impedance measurements reveal that the ionic conductivity of the electrolytes is beneficial for all solid lithium batteries dependent on the lithium content at room temperature.We found that the amorphous LLTO thin film performs well and it has potential application in microbatteries for use in microelectronic devices.     

Characterization of the rice canopy infested with brown spot disease using field hyperspectral data

Based on the field hyperspectral data from the analytical spectral devices (ASD) spectrometer, we characterized the spectral properties of rice canopies infested with brown spot disease and selected spectral regions and bands sensitive to four severity degrees (severe, moderate, light, and healthy). The results show that the curves’ variation on the original and the first-and second-order derivative curves are greatly different, but the spectral difference in the near-infrared region is the most obvious for each level. Specifically, the peaks are located at 822, 738, and 793 nm, while the valleys are located at 402, 570, and 753 nm, respectively. The sensitive regions are between 430-520, 530-550, and 650-710 nm, and the bands are 498, 539, and 673 nm in the sensitivity analysis, while they are in the ranges of 401-530, 550-730 as well as at 498 nm and 678 nm in the continuum removal.

电影海报的多模态语篇分析

信息时代,利用多模态对语篇进行分析已变得日益重要,在教学、生活、工作中都可以发现,人们使用多模态进行语篇分析的频率已越来越高。电影海报属于多模态文本,它的特点是将文字、图片、颜色和空间布局等各种符号系统融为一体。电影《非诚勿扰2》是冯小刚导演继《非诚勿扰1》后的一续集。本文从HALLIDAY的元功能思想分析《非诚勿扰2》海报的再现意义、互动意义和构图意义,以及各种模态对构图意义的协作和互补作用。
