人们对仿生学并不陌生。仿生机械、仿生运动、仿生建筑、仿生飞机等等,仿生学的许多研究成果正造福于我们。仿生学这个词来源于希腊文“Bion”,其含义是生命的单位。仿生学乇要是通过观察、研究和模拟自然界生物各种各样的特异性能,并且将这些优异的性能运用到科学技术中去,来改磐旧的,创造新的装置和系统。国际知名的动物学家Wemer Nachtigll博士认为,仿生学就是“学习自然界的现象并将其作为技术创新的模式”。 相似文献

自1960年美国科学家斯蒂尔创立仿生学以来,仿生学历经30余年,已有长足发展。起初,仿生学单纯以模仿生物的结构和器官为目标,设计出“电子蛙眼”、“晌尾蛇导弹”、“雷达”等人造传感器,“叶桥”、“薄壳穹顶”和“机械手”、“鲸形舟”等仿生器械。这些仿生设计 相似文献

在体育教学中尝试运动仿生练习既是对我国宝贵文化遗产的继承。又是对仿生学，特别是对运动仿生学、仿生体育、仿生健康学等学科的丰富和拓展，还是立足校本、与时俱进地践行新课程的具体表现，是体育教学的一种新视角。 相似文献

各种科技资料中有很多新颖的仿生船，如摆尾船、喷水船等，然而，这些仿生船的模型却很少见。能否利用身边废弃的塑料瓶为船身，玩具电动机为船的动力，运用电学、力学和仿生学等知识，应用简单易行的制作工艺，来制作塑料瓶仿生船的动态模型呢？我们的想法得到了老师的支持和帮助，设计制作了三种仿生船：“离心式喷水船”、“曲柄连杆式摆尾船”和“曲轴滑槽式摆尾船”，并命名为“一组塑料瓶仿生船模型”。离心式喷水船是把我们学过和做过的离心式水泵，模拟墨斗鱼喷水动作研制出来的，巧妙地利用软轴传动（气门芯胶管），把电动机轴的转… 相似文献

仿生设计,顾名思义是指有关模仿生物的设计。自从20世纪60年代仿生学作为一门学科正式诞生以来,经过几十年的探索与实践,巳发展成为横跨多门学科的边缘性学科。服装仿生设计作为仿生学的一个重要分支,也得到了广泛的研究与应用。从童装的仿生设计角度入手,研究童装仿生设计方法,探讨童装仿生设计当中的规律。并且从儿童的角度研究了几种主要的童装仿生方法,既可以使儿童穿上自己喜欢的仿生童装,也能够培养儿童的智力发展和兴趣发展。 相似文献

20亿年的进化历程使得自然界生物体的结构奇妙无比。人类的发明创造，有许多就是源于大自然的启示。自上世纪60年代仿生学诞生以来，仿生材料学就成为一个重要的研究与开发领域，并得到了迅速的发展，但是迄今为止仿生材料学未开拓的领域和未解决的问题还非常多，如何能从大自然中获得启示，设法解开这一秘密，是仿生材料学的研究课题。 相似文献

仿生,在科学技术中有着广泛的运用,在教育教学及其研究中也应该有着重要的应用价值。很久以来,人们在教育教学中一直在不自觉地运用仿生的思想、方法。为了改变教育教学及其研究的现状,我们应该自觉地运用仿生思想,直至建立教育仿生学。 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

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

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

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
