研究始于问题;科学研究始于科学问题.如何在问题中甄别出科学问题并发现科学研究选题,是科学研究开始的第一步.选题的来源可以在如下几方面去寻找:从社会现实中发现问题;从理论中寻找破绽;从学说的对立面提出观点;在综合统一思想下整合突破;从学科交叉处开垦“荒地”;在科学研究中意外发现.确立选题应遵循:新颖性、科学性、价值性和量力性四条基本原则. 相似文献

在高中生物教学中开展研究性学习可采取以下几个步骤1.确定研究课题;2.制订研究方案;3.实施研究方案;4.收集、分析、加工资料;撰写研究报告;6.研究课题成果的交流。开展研究性学习要正确看待学生;教师要充分认识自身;要充分发挥学生的主体作用。研究性学习不只是一个理论问题,也是一个实践问题,对开展研究性学习中的诸多问题还需进一步认真思考、探索与研究。 相似文献

马克思劳动价值论的历史地位及其当代意义 总被引:2,自引:0,他引:2
劳动价值论在马克思经济学中的重要地位决定 ,对劳动价值论的发展和创新 ,应该建立在对马克思劳动价值论的形成历史、科学方法和理论体系的深刻理解上。在深化对劳动价值论的研究中 ,有必要对以下问题做出新的探索 :1 .价值实体与“总体工人”的问题 ;2 .劳动凝结的物质性与非物质性问题 ;3.价值形成与财富创造的问题 ;4.活劳动与物化劳动问题 ;5 .国际价值问题 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects.

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. 相似文献

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. 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

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. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献
