当代艺术设计中“中国元素”表达与融合问题的研究

在当代中西方艺术设计领域中,＂中国元素＂已经作为了一种相当普遍的现象和形式出现在了众多艺术作品和设计之中,并且展现了其独特的文化特色和历史底蕴,为当代设计艺术的发展及其推陈出新提供了丰富的创作素材和灵感。本文首先解析了＂中国元素＂的内涵,接着就当代艺术设计中所体现出来的＂中国元素＂的特征进行了分析,并剖析了其与中国传统文化艺术的渊源关系,最后论述和研究了当代艺术设计与＂中国元素＂的表达和融合的机制。     

探析德国“新表”怪杰马库斯·吕佩尔茨的艺术风格

谈到吕佩尔兹几乎让人们不想到德国新表现主义。同时也不可避免要涉及到他作为杜塞尔多夫艺术学院的院长的成就。无论从艺术风格、生活方式以及表达方式,吕佩尔兹无可争议的作为当今现代德国艺术家中。在众多德国现代艺术家中．名声显赫。独领风骚。     

论“潇湘八景”画题与《坐铺八景》

文章首先概述潇湘八景在日本传播发展的大致特点,之后重点针对铃木春信的《坐铺八景》这一组作品如何对应潇湘八景的每一个画题逐一做详细探讨,并深入阐释了春信作品如何将江户时代一个普遍的创作手法——“见立”创造性的运用于八景画题的独特特点。     

On the thermal stability of xanthan gum

The thermal stability of xanthan gum in dilute aqueous solutions at 90°C is considered. The relative viscosity as a function of ageing time is discussed, and it has been found to depend on the polymer concentration and conformation as well as on the salt content. The effectiveness of a quencher demonstrates the existence of a free-radical process in the degradation. During ageing, the molecular weight first decreases by rapid random hydrolysis of the main chain and loss of the pyruvate and acetate substituents. Later, oligomers are formed corresponding to a breakdown of both the side chain and the main chain. The identification of cellodextrins in the oligomer pool demonstrates the second effect.

CGA560增强助磨剂在水泥粉磨中的应用研究

研究了CGA560增强助磨剂在水泥粉磨中对台时产量和水泥质量的影响。试验结果表明:在磨机状况不改变的条件下,CGA560增强助磨剂的加入可提高磨机产量10%-30%;同时可有效减少过粉磨现象,优化水泥颗粒级配,提高了水泥粉磨细度及比表面积;因而使水泥强度等性能得到了明显改善和提高。     

Photostabilization of cationic UV-cured coatings in the presence of nanoTiO2

The effect of TiO₂ nanoparticles for sun-weathering protection of UV-cured coatings is investigated. TiO₂ is either introduced in the form of nanoparticles in the photocurable formulations or generated in situ via sol–gel process. Cured films containing comparable amounts of TiO₂ were weathered for 800 h under UV irradiation and compared with free-TiO₂ coating. The TiO₂ presence induces a clear lower mass loss decrease during weathering as well as a lower gel content decrease. The TiO₂ screen effect is also confirmed by a lower alkyl-band reduction monitored by FT-IR during weathering. The TiO₂ generated in situ via sol–gel gives rise to transparent coatings without interfering with photopolymerization process and therefore without compromising UV-cured film properties.
