篇一:造纸术英文版

Paper-making is one of the four great inventions of China, the paper is the han long experience accumulation and the crystallization of the wisdom of working people, human a brilliant invention in the history of civilization. China is the world's earliest sericulture silk in the world. Han Chinese working people above cocoon silk silk, such as the remaining evil cocoon, cocoon disease such as flocculant with legal system take silk floss. After floating flocculant, woven bamboo mat legacy will be some residual effect. When the number of floating flocculant, woven bamboo mat on the residual flocculant product into a layer of fiber sheet, after dry stripping down, can be used for writing. This flocculant floating there aren't many by-products, and call it HeTi or FangXu on ancient book. This suggests that the origin of the han Chinese papermaking flocculant with silk have origin relations. 造纸术是中国四大发明之一,纸是汉族劳动人民长期经验的积累和智慧的结晶,人类文明史上的一项杰出的发明创造。中国是世界上最早养蚕织丝的国家。汉族劳动人民以上等蚕茧抽丝织绸,剩下的恶茧、病茧等则用漂絮法制取丝绵。漂絮完毕,篾席上会遗留一些残絮。当漂絮的次数多了,篾席上的残絮便积成一层纤维薄片,经晾干之后剥离下来,可用于书写。这种漂絮的副产物数量不多,在古书上称它为赫蹏或方絮。这表明了中国汉族造纸术的起源同丝絮有着渊源关系。

By CAI lun in eastern han dynasty (105) of the first year of yuan xing papermaking, improved by CAI lun in the bark, hemp heads and our raw materials such as cloth, fishing nets, after falling, dao, copy paper, drying technology, manufacturing, is the origin of modern paper. This paper, the raw material is easy to find and very cheap, quality is also improved, gradually widely used. In honour of the feat, CAI lun later generations called this paper "Cai Hou paper"

东汉元兴元年(105)蔡伦改进了造纸术,他用树皮、麻头及敝布、鱼网等原料,经过挫、捣、抄、烘等工艺制造的纸,是现代纸的渊源。这种纸,原料容易找到,又很便宜,质量也提高了,逐渐普遍使用。为纪念蔡伦的功绩,后人把这种纸叫做“蔡侯纸”

Until the eastern han dynasty and emperor period, through improved by CAI lun, formed a set of relatively finalize the design of the papermaking process, the process can be roughly divided (来自:WWw.SmhaiDa.com 海达范文网:蔡伦造纸的英语作文)into four steps:

The first is the separation of raw material, is to use the retting leaching or cooking methods for raw materials in alkali degumming, and scattered into fibrous;

Second is beating, is to use the method of cutting and struck staple fiber, and make the fiber broom, and become the pulp;

The third is the manufacture paper with pulp, namely make pulp water penetration into slurry, then used for paper pulp (woven bamboo mat) and get the pulp in paper to woven thin sheet of wet paper;

The fourth is dry, namely the wet paper to dry or dry, peeling the became a paper.

直到东汉和帝时期,经过了蔡伦的改进,形成了一套较为定型的造纸工艺流程,其过程大致可归纳为四个步骤:

第一是原料的分离,就是用沤浸或蒸煮的方法让原料在碱液中脱胶,并分散成纤维状; 第二是打浆,就是用切割和捶捣的方法切断纤维,并使纤维帚化,而成为纸浆;

第三是抄造,即把纸浆渗水制成浆液,然后用捞纸器(篾席)捞浆,使纸浆在捞纸器上交织成薄片状的湿纸;

第四是干燥,即把湿纸晒干或晾干,揭下就成为纸张。

篇二:蔡伦造纸

纸与蔡伦

——游蔡伦造纸博物馆有感 蔡伦(61~121)字敬仲,汉族,东汉桂阳郡人。中国古

代四大发明中造纸术的改造者(非发明者)。作为一名古

代宦官,他曾在昂贵的丝绸和竹板上书写过。永平末年

(75

)入宫为 宦官 。历任 小黄门、中常侍 兼尚方令、

长乐太仆

等职。元初元年(114),安帝封其为龙亭侯(封

地在今陕西省

洋县 龙亭铺镇),食邑三百户。蔡伦为人敦厚谨慎,关心国家利益,曾“数犯 严颜 ”,匡弼

时政。勤奋好学,办事专心尽力。造纸博物馆位于湖南耒阳。现代的造纸程序可分为制浆、调制、抄造、加工等主要步骤:1.制浆的过程 制浆为造纸的第一步,一般将木材转变成纸浆

的方法有机械制浆法、化学制浆法和半化学制浆法等三种。

2.调制过程 纸料的调制为造纸的另一重点,纸张完成后的

强度、色调、印刷性的优劣、纸张保存期限的长短直接与

它有关。一般常见的调制过程大致可分为以下三步骤: a.

散浆

b.打浆 c.加胶与充填 3.抄造过程 抄纸部门的主要工作为将稀的纸料,

使其均匀的交织和脱水,再经干燥、压光、卷纸、裁切、选别、包装,故一般常见之流程如下:a.纸料的筛选 将调制过的纸料再稀释成较低的浓度,并借着筛选设备,再次的筛除杂物及未解离纤维束,以保持品质及保护设备。b.

网 部 使纸料从头箱流出在循环的铜丝网或塑料网上并均匀的分布和交织。c.压榨部

将网面移开的湿纸引到一附有毛布的二个滚辘间,藉滚辘的压挤和毛布的吸水作用,将湿纸作进一步的脱水,并使纸质较紧密,以改善纸面,增加强度。d.压

光 由于经过压榨后的湿纸,其含水量仍高达52 - 70%,此时已无法再利用机械力来压除水分,故改让湿纸经过许多个内通热蒸气的圆筒表面使纸干燥。

e.卷 纸 由于经过压榨后的湿纸,其含水量仍高达52 - 70%

,此时已无法再利用机械力来压除水分,故改让湿纸经过许多个内通热蒸气的圆筒表面使纸干燥。f.裁切、选别 包装:取前面已卷成筒状的纸卷多支,用裁纸机裁成一张张的纸,再经人

工或机械的选别,剔除有破损或污点的纸张,最后包装起来。我爱你,纸,谢谢你为我们做贡献!

篇四:蔡伦造纸故事

故事:《蔡伦造纸》

很久很久以前,文字是刻在甲骨上,或是写在竹简、丝绢上的,这些材料有的十分笨重、有的十分昂贵,给人们造成了许多不便。 在两千多年前的西汉时期,有些人便开始使用一些较为便宜的植物纤维造纸,可这种纸看起来十分粗糙,书写起来仍然很不方便。到了东汉时期,有个叫蔡伦的宦官决心为人们寻找一种实用的造纸方法。

蔡伦经常到河边,观察妇女们洗蚕丝和抽蚕丝的“漂絮”过程。他发现好的蚕丝拿走后所剩下的破乱蚕丝,会在席上形成簿簿的一层东西。有人就把它晒干,用来糊窗户、包东西,或是用来写字。 他到造纸的作坊,向造纸的工匠们请教,渐渐地了解和掌握了造纸的基本过程。为了造出既经济又实用的纸,蔡伦采用了树皮、麻皮、破布、废渔网等常见的材料,把它们捣碎,做成纸浆。

蔡伦天天试验,月月试验,把自己弄得整天脏兮兮的,周围的人都把他当作怪人,不愿意接近他。可他从不理会那些异样的目光,依旧埋头研究他的造纸新方法。

他采用“漂絮”的方法,用席子去捞那些纸浆,捞出来的纸浆就会在席子上形成簿簿的一层,晒干后就成了纸。

蔡伦终于成功了。他造出了价格低廉、便于携带和书写的纸,这一伟大发明被列为我国古代四大发明之一。

故事:《蔡伦造纸》

很久很久以前,我们的祖先是把字写在竹片上,叫做竹简,再用皮带子或绳子把一片片竹简编串起来,就像竹帘子一样,就成了册,相当于现在的书。因为一片片的竹简写不了多少字,所以现在的几页书,那时候就是重重的一大册呢。而古人的一部书,总要编很多册,小孩子如果带一部书上学堂,很有可能要拿大篓子来当书包。竹简不仅太重,太占地方,而且字容易抹掉、生虫,不管怎么处理,也改进不了多少。书一直是困扰读书人的最大问题。

蔡伦那个年代,人们已经学会了养蚕取丝,他们把煮好的蚕茧用棍子敲烂,铺在席子上,就成了丝绵。人们把丝绵取下后,将留在席子上的一层薄薄的纤维晒干,就成了纸。有人发现丝纸可以书写文字,用起来比竹简方便多了。但这种丝纸还不能算是真正的纸,而且这种纸的原材料是丝,产量少,价钱昂贵,一般人用不起。所以那时候读书写字实在好苦。

蔡伦学问很高,在皇宫里做官,经常用到纸。日子久了,蔡伦觉得丝纸的用量太大,花费太多,心里很烦恼。

有一天,宫廷里来了一位新的工匠,叫黄昌,是从出产蚕丝的江南来的。蔡伦找到他,说:“我一直想知道,丝纸是怎样做出来的?能不能请你把详细的方法告诉我?”黄昌便一五一十地告诉他。从此,蔡伦就天天动脑筋想有没有其他便宜的东西来代替丝做纸。

一天,蔡伦把黄昌叫来,问他:“丝纸是做丝绵剩下的纤维吗?”

黄昌说:“是一层很薄的纤维。”蔡伦说:“如果我们用其他有纤维的东西来代替丝,是不是也可以做出纸呢?”于是,他们开始了实验。蔡伦找来树皮、麻叶,全部放到大锅中,加上水煮,黄昌还抱来了破布、破鱼网放入锅中,蔡伦说:“好啊,只要有纤维的东西,我们都可以试试。”等到锅中的水沸腾,两个人就合力把乱七八糟的东西到入大石臼,再用木棒“笃笃”地捣了起来。等石臼中的所有东西都被捣烂混合成浆状,黄昌便用漂白剂漂白,然后把浆平铺在席子上,铺得又薄又平有均匀,最后把纸撕下,高兴地大叫:“这的确是张完整的纸啊!”蔡伦在纸上写上字看效果,兴奋地说:“成功了,这张纸比原来的丝纸吸墨快,而且不容易散开,这才能算是真正的纸啊!” 蔡伦造纸成功后,全国各地开始大量制造、使用这种纸。直到现在,我们使用的宣纸、绵纸还沿用着当初蔡伦造纸的方法,只是现在用的材料已经变成了竹子、木材等。

篇五:蔡伦造纸

蔡伦造纸

(过程:挫切 - 沤料 - 漂白 - 捣浆 - 稀释 - 操舀 - 挤压 - 晾干) 蔡伦率领几名皇室作坊中的技工利用丰富的水资源和树木,剥树皮,捣碎,泡烂,再加入沤松的麻缕,制成稀浆,用竹蔑薄薄捞出一层凉干,揭下,造出了最初的纸。试用后,发现容易破烂,又将破布、烂鱼网捣碎等,掺进浆中,再制成的纸便难以扯破了。为了加快制纸进度,蔡伦又指挥大家盖起了烘焙房,湿纸上墙烘干,不仅速度快,且纸张平整,更让大家乐开了花。造出了些纸,进献给和帝。和帝试用后龙颜大悦,当天就驾幸陈河谷造纸作坊,查看了造纸过程,回宫后重赏蔡伦,并诏告天下,推广造纸技术。

毕升

毕升(?~约1051)北宋发明家。徽州(今安徽歙县)人。活字印刷术的发明者。我国是最早发明印刷术的国家,早期的印刷方法是把图文刻在木板上用水墨印刷的,现在的木板水印画仍用此法,统称为“刻版印刷术”。宋代庆历(公元1041年)间,毕升首创泥活字版,使书籍印刷更为方便。据沈括的《梦溪笔谈》记载,毕升发明在胶泥片上刻字,一字一印,用为烧硬后,便成活字。排版前,先在置有铁框的铁框的铁板上敷一层搀和纸灰的松脂蜡,活字依次排在上面,加热,使蜡稍溶化,以平板压平字面,泥字即因著在铁板上,可以象雕板一样印刷。

火药

火药在现代一般用于制作烟花爆竹等。中国四大发明之一。人类文明史上的一项杰出的成就。火药又被称为黑火药。是在适当的外界能量作用下,自身能进行迅速而有规律的燃烧,同时生成大量高温燃气的物质。在军事上主要用作枪弹、炮弹的发射药和火箭、导弹的推进剂及其他驱动装置的能源,是弹药的重要组成部分。

指南针应用实例

在野外旅行(野外行军)中,通常是要穿越没有熟悉地形地物的地区,这个时候就要用指南针来标定地图和确认方向。每个公园地图都有一个指示方向的指针。

四大发明对世界的影响

造纸、印刷术、火药、指南针四大发明是中华民族对世界文明的伟大贡献,四大发明深刻影响了世界文明的进程。这些发明改变了世界的面貌和万事万物的原有状态,其波及范围不限于某一局部地区,而是整个世界;其影响所及不是一时一世,而是持续千百年之久。

中国古代的科学技术,自然不能不说古代的四大发明,指南针、造纸术、印刷术、火药,四大发明不仅仅是中国古代科学技术繁荣的标志和中国人民聪明智慧的体现,更重要的是它在一定程度上改变了人类近代文明的进程。换句话说,如果没有中国古代的四大文明,也许人类社会不是今天这个样子。这可不是中国人的自吹自擂,因为世界史学界一致认为,中国的四大发明,通过阿拉伯人传到欧欧洲之后,给欧洲人的社会产生巨大的影响,从而影响了人类的整个进程。
