人民版必修Ⅲ专题二关于蔡伦造纸是这么说的：“东汉时,蔡伦独创新意,使用树皮、麻头、破布和旧渔网加工造成新的书写材料——纸,在元兴元年（105年）呈献给汉和帝。皇帝赞赏他的巧思精意,封他为侯,从此这种纸被称为‘蔡侯纸’。”这里,“皇帝”当然是指汉和帝,蔡伦封侯的原因是造纸。但《后汉书·蔡伦传》记载：“元初元年,邓太后以伦... 相似文献

二三六 谷 用布或纸裱糊成厚片,用来作布鞋或书套等物,北京话谓之“袼褙”ge bei,河东方言则谓之“褙纸”Peizhi或“谷”gu;“打袼褙”俗称为“抹谷”。为什么“袼褙”会称为“谷”呢?这同我国古代造纸术很有点关系。我们都知道,纸是东汉宦官蔡伦发明的。那么蔡伦当初造的是一种什么纸呢?《后汉书》宦者列传六十八《蔡伦传》说:“自古书契多编以竹简,其用缣帛者谓之为纸。缣贵而简重,并不便于人。伦乃 相似文献

问:蔡伦是改进了造纸的方法还是发明了造纸的方法?(安徽革命残废军人第一速成中学教导处)答:蔡伦以前确已有纸。但当时的纸与今日的纸是完全不同质的东西。根据现在的纪录,蔡伦造纸(东汉和帝天兴元年,公历一○五年)以前所谓“纸”大约有以下两种:一种就是细薄的绸子,据後汉书蔡伦传:“自古书契多编以竹简,其用缣帛者,谓之为纸”,这种书写用的绸“纸”今日考古学家在敦煌以北接近古长城遗址的交通路上曾有发见,因生丝易腐,所以存者不多。另一种大约是用丝绵漂制成的东西。据许慎说文解字(东汉和帝永元十二年,公历一○○年顷编纂):“纸,絮一(竹沾)也)。清段玉裁 相似文献

在学完《纸的发明和蔡伦改进造纸术》后．有位学生提出这样一个问题：教材上说蔡伦改进造纸术后．“蔡侯纸”逐渐普遍使用．为什么高希希导演的电视剧新版《三国》中的书写材料都是竹简呢？这位学生提出了一个让许多人没在意的问题。《后汉书·蔡伦传》载：“自古书契多编以竹简．其用缣帛者谓之为纸。缣贵而简重．并不便于人。 相似文献

纸是中国古代四大发明之一，在考古界未发现纸以前的2700多年中，一直认为是东汉蔡伦发明纸。西汉纸的相继发现，将中国纸的发明又提前了200多年，为蔡伦改进造纸工艺、制造更加适用的纸奠定了基础。西汉已有纸和蔡伦发明纸之说并不矛盾，它证明了一项科学发明的过程，使蔡伦造纸说更加科学和合理。 相似文献

蔡伦造纸 ,见《后汉书·蔡伦传》 :“自古书契 ,多编以竹简 ,其用缣帛者 ,谓之为纸。缣贵而简重 ,并不便于人。伦乃造意 ,用树肤、麻头 ,及敝布、渔网以为纸。元兴元年 (西历一○五年 )奏上之 ,帝善其能。自是莫不从用焉。故天下咸称蔡侯纸。”蔡伦是东汉和帝时的一名宦官 ,亏他想出以植物纤维造纸的方法。造纸的原料各地不同 ,据苏易简《纸谱》说 :“蜀人以麻 ,闽人以嫩竹 ,北人以桑皮 ,剡溪人以藤 ,海人以苔 ,浙人以麦面稻秆 ,吴人以茧 ,楚人以楮为纸。”多是植物性纤维 ,就地取材。我国的造纸术 ,于蔡伦后六百多年传到中亚 ,再经四百年传… 相似文献

蔡伦造纸,在清以前,几乎是中国人家喻户晓的提法;纸的发明也是世界公认的中华民族聪明才智的结晶,是对整个人类文化的巨大贡献。但由于近数十年来考古发现了四例西汉纸(1933年黄文弼先生发现的新疆“罗布卓尔”纸、1957年西安市灞桥西汉墓葬中的“灞桥纸”、1973年汉居延遗址中的“金关纸”和1978年陕西扶风中颜村西汉墓中的“中颜纸”),技术鉴定这四种纸均为 相似文献

本文从有关否定蔡伦造纸术的争论谈起,引据历史典籍文献和科学检验的材料,考察了历史上的文字信息书写载体的一般形态,论析了蔡侯纸与之相较的先进性实用性,进而论析制造蔡侯纸的蔡伦造纸术是一个完整系统的科学发明,在此基础上辩析了否定蔡伦造纸术在科学概念方面的逻辑混乱,最后进一步肯定蔡伦发明纸和造纸术的历史贡献,肯定蔡伦发明的地位没有动摇。 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

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

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

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. 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

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. 相似文献
