Finally, the writer argues, that, to solve the present problem of Chinese computer music education, depends on the following: 1） to increase the education investment, to enlarge the group of educatee by the different educational model, to produce self-developing mechanism and to expend the educational area according to the facts and the social developing demands. 2） to reform the course structure and to contribute its content base on applicably, scientifically and practically. 3） to train the specialized and complex teachers intentionally.

最后，笔者根据我国计算机音乐教育与美国等发达国家的差距和现阶段国内发展计算机音乐教育需要解决的实际问题，提出了自己的三点看法和九个初步的解决策略：1、采用增加教育投入、多种形式的教学模式扩大受教育者范围、营造自身发展机制、根据实际情况和社会需求重点建设来扩大教育规模；2、根据适应性原则、科学性原则和实用性原则来进行课程的结构改革和内容建设；3、有意识地从注重专业型和复合型人才两方面培养自己的教师队伍。

This paper discusses the main reasons why jadeite jade culture was developed in a short time during the middle-late Qing dynasty. It concludes that three main reasons precipitate the rising of jadeite jade culture; the influence of folk customs of the Manchu ethnic group, the power structure of royal estate, and development of aulic culture; the change of social values influenced by Western culture and the commercial development of the Qing dynasty.

文章讨论了导致翡翠玉文化在我国清代中晚期形成的主要原因，认为满族民俗的影响，皇室权力结构改变及宫廷文化的推动；西方文化传入导致的价值观念转变；清代商业经济发展等要素是导致翡翠玉文化能在较短时间内得以与和田玉文化并驾齐驱的主要原因。

Computationalresults indicate that the no-planar trans-benzanilide is the most stable structure. The spectra indicate that the Franck Condon region photodissociation dynamics have multidimensional character withnine activemodes. The intensity of υ24 mode in methanol is much stronger than that in acetonitrile. Compared with fatty amides and benzamide, phenyl substitution for H atom on-NH2 group makes C=O solvent effects disappear.

结果表明，苯甲酰苯胺的非平面反式结构为最稳定结构；在Frank-Condon区域内，苯甲酰苯胺主要由9个活性振动模组成；其中ν24（苯环上C＝C不对称伸缩振动和CCH的面内弯曲振动，NH面内弯曲振动）振动模在甲醇溶剂中的强度远远大于其在乙腈的强度；与脂肪酰胺类化合物和苯甲酰胺的研究结果比较发现，苯基取代－NH2上的H原子使得C＝O不再具有明显的溶剂效应。

The chiral polymer P-1 shows strong blue fluorescence due to the extended π-electronic structure between the chiral repeating unit-6,6'-di(4-trifluoromethyl-phenyl)-2,2'-bisoctoxy-1,1'-binaphthyl and the conjugated linker 2,2'-bipyridyl group via vinylene bridge.

手性高分子P-1能发射强的蓝色荧光，这是由于手性重复单元-6，6′-二(4-三氟甲基苯基)-2，2′-二正辛氧基-1，1′-联萘和单元2，2′-联吡啶通过亚乙烯基桥连形成共轭高分子结构造成的。
