络合物的制备及其结构测定的研究

CrCl_3·6H_2O是一种络合物,它有三种异构体:[CrCl_2(H_2O)_4]Cl·2H_2O暗绿、[CrCl (H_2O)_5]Cl_2·H_2O淡绿、[Cr(H_2O)_6]Cl_3紫色。不同的合成制备条件得出不同的异构体。本论文通过对合成样品进行电导、离子电荷和紫外可见光谱曲线等组成测定的研究,并由其确定络合物结构的最终类型,使我们对生产配合物的水合异构现象有了深刻的了解和掌握,为配合物结构类型的确定提供了新的一种简便方法。     

19世纪末20世纪初美国普瑞特图书馆学校的儿童图书馆员教育

19世纪末,美国普瑞特图书馆学校尝试在一年制图书馆常规技能教育的基础上拓展专业的儿童图书馆员培训,开启了美国儿童图书馆员教育的先河,为第二代儿童图书馆员提供了专门训练,并与20世纪上半叶最具影响力的匹兹堡卡内基儿童图书馆员培训学校有着天然的联系.由其创办者和主要实践者的儿童工作和儿童馆员教育理念出发,探讨普瑞特图书馆学...

穆尔与叶赛宁诗歌中的生态原型意象对比研究

美国诗人玛丽安娜.穆尔与俄罗斯诗人谢尔盖.叶赛宁分别在各自诗作中以＂原型＂的方式建构各类神启意象,如极光、雾霭、印第安部落、森林界碑、烟囱、铁轨等。具有生态指涉意义的神启意象在二者创作中呈现动态演化的特点,在二者早、中、晚期诗歌里分别启示着生态理想、生态责任和生态预警。神启意象统辖着二者各时期诗歌的生态话语场,以最本质的方式折射出诗人特定时期的生态意识。     

半正定矩阵广义Schur补的若干不等式

利用半正定矩阵的性质和矩阵Moore-Penrose广义逆的特性,研究了半正定矩阵广义Schur补问题.证明了对半正定矩阵A有(A/α)*(A/α)≥A*A/α,并由此得到了一些有关广义Schur补的不等式.将半正定矩阵Schur补的相关结果推广至广义Schur补.     

Tailoring Modified Moore Method Techniques to Liberal Arts Mathematics Courses

Abstract

Inquiry-based learning (IBL) techniques can be used in mathematics courses for non-majors, such as courses required for liberal arts majors to fulfill graduation requirements. Unique challenges are discussed, followed by adaptations of IBL techniques to overcome those challenges.     

The Marriage of Marianne Moore to The Tao of Chinese Painting

Marianne Moore was a modernist poet greatly influenced by Chinese art and the Taoist aesthetic.Her passion for Chinese culture never ceased to grow from her earliest contact with the Chinese paintings and artwork introduced to the western countries in the early 20th century.Her early poem entitled "The Fish" and a later one entitled "Tell me,Tell me" serve as two typical examples to show the marriage of Chinese elements to her American poetic ideas.     

玛丽安·摩尔的诗歌和中国绘画之道

美国现代主义诗人玛丽安·摩尔的诗歌创作深受中国绘画的影响。她早期的诗歌在意象、形式和表现手法上均．与中国绘画有共通之处;施美美的《绘画之道》使她对中国绘画及其相关哲学有了深入和系统的理解,完善了她的审美观;后期的作品《告诉我,告诉我》堪称她诗歌创作和中国绘画之道完美契合的典范。     

Culture and counseling in the Philippines

An examination of experiences as a counselor in the Philippines suggests at least three important domains of difference in the counseling process: the content of problems, modes of relationships and presumed causes of difficulties. Filipino counselees in a university setting struggled with family control, and rebelled against a double standard of morals. They found it difficult to trust a counselor who was not part of the extended family and they attributed their difficulties to external, social rather than intrapsychic factors. In light of these cultural differences counselors must respond to their problems as Filipinos perceive them and explore ways of changing the social environment of the client. This is in contrast to the strategy of North American counselors who seek to change the client's methods of dealing with himself.
