该文介绍了一种不受时间、空间和技术限制的全方位实验室开放形式，学生可以课外在导师带领下充分利用实验室的技术、设备和空间资源进行实验研究，同时在实验教学时学生也可以进入教师科研室进行实验。实验室经历了技术的输入和输出过程，即实验室技术平台形成的过程，实验室管理也逐渐向实验项目开发和实验技术管理转变，逐渐成为到供学生研究性学习、实践的研究型实验室。 相似文献

《普通高中物理课程标准》提到，实验是物理课程改革的重要环节，是落实物理课程目标、全面提高学生科学素养的重要途径．在实验改革过程中，应该建立开放性实验室：应安排足够的学生实验和演示实验；应最大限度地利用实验室现有的器材；充分地开发和利用实验室的丰富课程资源，尽快改变实验室封闭式的管理状态，实验室应该尽快向学生开放，让学生能够自主地做实验．然而，由于实验器材（包括贵重仪器）的有限、实验室实行开放式管理带来种种问题等因素，建立开放性实验室面临一定的困难．基于网络的全天候无人值守开放的远程实验在建立开放性实验室方面有独特的优势，而且对新课程标准下的三维目标有不同于传统实验模式的支持作用．[第一段] 相似文献

当今，发达国家都非常重视高校实验室的建设，因为２１世纪是科学技术高速发展的知识经济时代，现代科学需要有实验能力及创新能力的科技人才。实验教学恰是开发学生智力和培养学生能力的重要途径，笔者结合体育专业实验室的建设与管理谈一些改革思路。一、重新认识实验室在教学中的地位和作用高等院校的体育专业，按国家教委计划和培养目标，应开设人体生理学实验、人体解剖学实验、运动生理学实验、运动生物力学实验、运动心理学实验等，要完成上述实验，必须分学科建立实验室。但由于经费不足，实验用房紧张，人员编制不足，使这些实验室… 相似文献

高校实验室管理信息化、智能化，是高效实验教学的前提.但现有实验教学环境中，缺乏针对提高实验室管理和设备利用率的辅助管理平台.为此，根据教学、科研实验室的不同性质，遵循优化配置和效益原则，提出了相关公式和利用率算法，应用于实验室辅助管理平台.通过该平台可以随时了解实验室和实验仪器设备的现状和使用情况，实现了仪器设备、实验用房的可视化和精细化管理，极大地促进了实验室管理和创新人才培养. 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. 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. 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 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

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? 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

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
