《文源》取材三题

本文论及《文源》采用古文字资料的范围、《文源》不用甲骨文之谜和《文源》引用传统"说文学"资料等三个问题。从取材的角度看,《文源》是一部继承传统文字学特别是清代段、朱"说文学"的成就,同时又结合古文字资料尤其是商周秦汉金石文字资料来探讨汉字本形本义的承前启后的著作,它虽然还没来得及用上甲骨文的资料,但已经充分展示出古文字资料和传统文字学相结合给汉字学研究所带来的新气象。

对利用Web传递教学所面临的一些问题（Web连接速度、Web反应时间、教学材料的再处理以及数字化学习资料的提供）进行了分析研究。     

数字化实验系统在实验教学应用中的探讨

数字化实验系统是一个开放性的实验平台,与传统实验器材相比,它具有快速、高精度地实时采集数据,并自动记录和分析处理的特点.完善的数字化实验系统,在真实实验的基础上实现了新课标要求的“信息技术与物理学科教学的全面整合”.     

数字化实验系统在初中物理探究实验中的应用

介绍数字化实验系统,分析开展数字化实验应当遵循的科学性、针对性和适用性的设计原则,选取两个初中物理实验说明如何利用数字化实验系统优化探究过程。同时对数字化实验的优点和利弊提出思考。     

含有冷僻古汉字的字符串的计算机处理

一、问题的由来 Unicode标准解决了古籍数字化的码位短缺问题,也解决了不同系统码表的h差异造成的信息交换问题,同时,Unicode标准也使各种不同的语言平台之间有了一个共同的编码系统,使古籍的跨平台展现变成可能;而VB6.0不仅简单易学、界面友好,而且以Unicode为内核,提供了大量的字符串处理函数,具有强大的字符处理功能,因而,VB6.0成为我们在古籍研究中的首选编程工具.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
