传统镶嵌玻璃艺术在当代建筑中的转型与应用

玻璃镶嵌是西方传统的艺术表现形式,其与建筑的成长密切相关,中世纪哥特式建筑的辉煌使镶嵌玻璃艺术达到了前所未有的高度,这种影响力有效的延续至今。进入当代,随着建筑的发展、科技的进步以及观念的更新,镶嵌玻璃艺术创作发生了深刻的变化,镶嵌玻璃突破了传统的束缚,以新颖的形式、前卫的思想、广泛的应用渠道成为经营建筑空间、美化生活环境的重要艺术载体。文章将从传统镶嵌玻璃的起源出发,着眼镶嵌玻璃在当代艺术创作语境中的演变,探寻其转型的根本方式与思维方法,并在建筑中的应用拓展上作出前瞻性的预测。     

现代建筑艺术设计的创新研究——以镶嵌玻璃材料的设计及应用为例

文章分析以现代艺术发展为背景的现代建筑空间中的镶嵌玻璃艺术的发展走向与转型特征,认为传承建筑设计的人文思想,以公共艺术创作理念为根本,从现代建筑的结构与空间出发,拓展镶嵌玻璃的工艺技巧,不断突破传统镶嵌玻璃的创作观念,是进入当代镶嵌玻璃艺术设计语境的前提条件,并进一步结合建筑市场以及大众审美需求,从镶嵌玻璃的艺术价值出发,联系文化产业的发展现状,对镶嵌玻璃艺术发展的可能性做出预测。     

APPLICATION OF RECONSTRUCTION ANALYSIS IN SOLVING THE PROBLEM OF FLOAT GLASS STAINED WITH TIN

In float glass manufacturing, the glass is often stained with tin, which will result in deficient quality. The amount of stained tin is related to five factors: temperature, oxygen content in tin liqnid, bath pressure, total amount of protecting gas, and the thickness of the glass. On the basis of the experimental data, and through system reconstruction analysis, each factor's value range where there is not any tin stain on the float glass is found.     

HE染色乳腺癌组织病理图像癌巢与间质分割研究

HE染色的乳腺癌组织病理图像是分析诊断乳腺癌常用的方法,病理学家普遍认为癌巢和间质的病理形态学特征对研究乳腺癌的生物学行为有着预示作用,所以准确分割癌巢和间质显得尤为重要。对于HE染色乳腺癌组织病理图像,视癌巢和间质的分割为图像中像素点的分类问题,提取并分析特征,选取最佳特征组合,然后分类为癌巢或间质,并结合间隔采样、归一化与阈值法。实验表明,该方法能较为准确地分割出癌巢和间质,保证较高准确率和精度,在时间效率上能达到较为满意的结果。     

蛋白污布的染制均匀性对洗涤剂去污力评价的影响

采用球磨机代替手工磨制炭黑制备改进蛋白污布(改进JB-02),通过测试标准洗衣粉、市售洗衣粉和含蛋白酶的标准洗衣粉对改进JB-02的去污值来评价所制备污布的质量。结果表明,使用球磨机磨制相比于手工磨制的炭黑颗粒的粒径变小,粒度分布变窄,分散均匀性提高;改进JB-02的染制均一度提高;标准洗衣粉对改进JB-02的去污值提高;当标准洗衣粉中蛋白酶的质量分数低于0.15%时,改进JB-02对蛋白酶的敏感度提高;改进JB-02的稳定性较好,可考虑作为标准产品使用。

Automatic macroscopic density artefact removal in a Nissl‐stained microscopic atlas of whole mouse brain

Acquiring a whole mouse brain at the micrometer scale is a complex, continuous and time‐consuming process. Because of defects caused by sample preparation and microscopy, the acquired image data sets suffer from various macroscopic density artefacts that worsen the image quality. We have to develop the available preprocessing methods to improve image quality by removing the artefacts that effect cell segmentation, vascular tracing and visualization. In this study, a set of automatic artefact removal methods is proposed for images obtained by tissue staining and optical microscopy. These methods significantly improve the complicated images that contain various structures, including cells and blood vessels. The whole mouse brain data set with Nissl staining was tested, and the intensity of the processed images was uniformly distributed throughout different brain areas. Furthermore, the processed image data set with its uniform brightness and high quality is now a fundamental atlas for image analysis, including cell segmentation, vascular tracing and visualization.     

不同包埋剂对半薄切片甲苯胺蓝染色效果的影响

目的:探讨不同包埋剂对半薄切片甲苯胺蓝染色效果的影响。方法:切取大鼠的坐骨神经及肾脏组织,经戊二醛-锇酸双重固定,乙醇、丙酮梯度脱水后,分别用Epon812和Eponate12包埋聚合,利用超薄切片机制备厚度为1.5μm的半薄切片,切片经甲苯胺蓝染色,在光镜下观察半薄切片的染色效果。结果:Eponate12包埋的半薄切片经甲苯胺蓝染色后,颜色更鲜艳,微细结构更清晰,图像反差更好。结论:Eponate12包埋的半薄切片经甲苯胺蓝染色后更有利于在光镜下观察组织的微细结构。
