Flexible electrochromic(EC) materials have an urgent demand in the current electronic equipment market due to their technological interest and applications. However, at present, few flexible EC devices developed by industry exist due to some problems and challenges still to be solved such as flexibility. In this work, we have successfully synthesized a novel thiophene-furan(TFu) monomer via Stille coupling reaction,and facilely electrochemically polymerized in a neutral Bu_4 NPF_6-CH_2Cl2 electrolyte system to afford the corresponding poly(thiophene-furan)(PTFu) polymer film with good flexibility. The electrochemical and photoelectrochemical analyses of the as-prepared PTFu demonstrate that it has achieved the improved EC performance compared with pure polyfuran and polythiophene polymers, and as a result it possesses favorable EC parameters manifested as a reasonable ΔT(32.1%), faster response(1.38 s), excellent coloration efficiency(CE, 300.9 cm^(2)·C^(-1)), and after a continuous redox process up to 2000 s, its optical stability can be maintained at 96%, and even after 3000 s, it can still be maintained at 80%. In addition, the successful assembly of the electrochromic device of PTFu film can easily realize the reversible conversion of the color from orange to gray. All these systematic studies suggest that the as-prepared flexible PTFu film is a promising candidate for EC materials and has great potential interest for versatile EC applications.

关于练声曲教材现状的分析与思考

黄钟（武汉音乐学院学报） 2008年第3期 171-177页

作者：李首明广州大学音乐舞蹈学院音乐系

练声曲教材是声乐教学中不可或缺的一部分。作者以个别形式,对10余所音乐、艺术院校的20多位专业教师在教学中练声曲教材的使用情况、教学理念进行了访谈,并针对有关问题提出了自己的建议和设想:各类学校应结合自己的实际情况和特点将... 详细信息

练声曲教材是声乐教学中不可或缺的一部分。作者以个别形式,对10余所音乐、艺术院校的20多位专业教师在教学中练声曲教材的使用情况、教学理念进行了访谈,并针对有关问题提出了自己的建议和设想:各类学校应结合自己的实际情况和特点将合适的练声曲教材纳入教学计划及教材管理;应遵循根据声乐教学的特点,寻求声乐教学中的练声曲的共性,通过练声曲规范声乐教学的个性,力求用练声曲达到教学的目的性、针对性、科学性,以取得声乐教学的最佳效果。

艺术作品的意蕴生成于象征的艺术方式,其在表现上,则是暗示。"象征一般是直接呈现于感性观照的一种现成的外在事物,对这种外在事物并不直接就它本身来看,而是就它所暗示的一种较广泛较普遍的意义来看。对于其他艺术门类来说,象征只能就作品达到了"具有意蕴"的层次而言,音乐的象征则不是,要普遍得多;或确言之,象征是音乐最基本的艺术表达方式。

从接受美学视角审视音乐的再创造活动

接受美学主要是一种文学理论和文学研究方法。在接受美学那里,接受不仅是作为一个独立的美学范畴而存在着的,而且被看作是整个文学审美过程中的核心部分。正因为如此,接受者的主体作用,亦被同时摆放到空前重要的位置上。众所周知,文学... 详细信息

接受美学主要是一种文学理论和文学研究方法。在接受美学那里,接受不仅是作为一个独立的美学范畴而存在着的,而且被看作是整个文学审美过程中的核心部分。正因为如此,接受者的主体作用,亦被同时摆放到空前重要的位置上。众所周知,文学与艺术在本质上是相通的。再创造在音乐审美的实现过程中同样是必不可少的,音乐离不开表演,这是音乐与文学、绘画、雕塑等在表现方式上的不同之处。正是基于此,本文拟从接受美学的角度,对音乐审美过程中的再创造活动——包括二度创造:音乐表演,三度创造:音乐欣赏,进行审视与论述。
