指南针是用以判别方位的一种简单仪器。前身是司南。主要组成部分是一根装在轴上可以自由转动的磁针。磁针在地磁场作用下能保持在磁子午线的切线方向上。磁针的北极指向地理的北极,利用这一性能可以辨别方向。常用于航海、大地测量、旅行及军事等方面。指南针的N指北方,E指东方,W指西方,S 指南方。“磁针是铁打磨成的,铁属金,按五行生克说,金生水,而北方属水,因此北方之水是金之子。铁产生于磁石,磁石是受阳气的孕育而产生的,阳气属火,位于南方,因此南方相当于磁针之母。这样,磁针既要眷顾母亲,又要留恋子女,自然就要指向南

造纸术是中国四大发明之一,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。中国古代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。这表明了中国造纸术的起源同丝絮有着渊源关系。造纸术(也称蔡侯纸)蔡伦改进。东汉和帝元兴元年(公元105年),蔡伦在总结前人制造丝织晶的经验的基础上,用树皮、破渔网、破布、麻头等作为原料,制造成了适合书活字印刷术是一种古代印刷方法,是中国古代劳动人民经过长期实践和研究才发明的。先制成单字的阳文反文字模,然后按照稿件把单字挑选出来,排列在字盘内,涂墨印刷,印完后再将字模拆出,留待下次排印时再次使用。

活字印刷术的发明是印刷史上一次伟大的技术革命。北宋庆历间(1041年-1048年)中国的毕昇(970年—1051年)发明的泥活字,标志着活字印刷术的诞生。他是世界上第一个发明人,比德国人约翰内斯·古腾堡活字印刷术早约400年。元代王祯成功创制木活字,又发明了转轮排字。明代中期,铜活火药是中国古代炼丹家发明于隋唐时期,距今已有一千多年了。火药的研究开始于古代道家炼丹术,古人为求长生不老而炼制丹药,炼丹术的目的和动机都是超前的,但它的实验方法还是有可取之处,最后导致了火药的发明。

炼丹家虽然掌握了一定的化学方法,但是他们的方向是求长生不老之药,火药的发明是副产品。炼丹家对于硫磺、砒霜等具有猛毒的金石药,在使用之前,常用烧灼的办法“伏”一下,“伏”是降伏的意思。使毒性失去或减低,这种手续称为“伏火”。

Formerly known as Sinan. The main components are mounted on a shaft can freely rotate the needle (commonly known as magnet). Needle on the ground magnetic field can be maintained at the tangent magnetic radial direction. Needle points to the geographical North Pole South Pole, take advantage of this performance can be a sense of direction. Commonly used in navigation, geodesy, travel and military and so on. (一)指南针 指南针是用以判别方位的一种简单仪器。前身是司南。主要组成部分是一根装在轴上可以自由转动的磁针(俗称吸铁石)。磁针在地磁场作用下能保持在磁子午线的切线方向上。磁针的北极指向地理的南极,利用这一性能可以辨别方向。常用于航海、大地测量、旅行及军事等方面。 Compass invented the ancient Chinese practice of long-term understanding of the results of magnetic objects. Ancient Chinese people into contact with magnetite, as he began to understand the nature of magnetism. It cited the first to discover the magnetic properties of iron. Then they discovered that the directivity of the magnet. After many experiments and studies, and finally invented the compass can be useful. 指南针的发明是中国古人在长期的实践中对物体磁性认识的结果。古代中国人接触了磁铁矿,开始了对磁性质的了解。人们首先发现了磁石引铁的性质。后来又发现了磁石的指向性。经过多方的实验和研究,终于发明了可以实用的指南针。 (二)Gunpowder With saltpeter, sulfur and charcoal made from these three kinds of material mixed, but when people have these three kinds of things as the treatment of drug, so the name "gunpowder", meaning "fire medicine." (一)火药 用硝石、硫黄和木碳这三种物质混和制成的,而当时人们都把这三种东西作为治病的药物,所以取名“火药”,意思是“着火的药”。 Since the Qin and Han dynasties, alchemy home sulfur, saltpeter and other items make pills of immortality, from the accidental explosion of the phenomenon of inspiration, and then after repeated practice, and found the powder formula. Wei during the Three Kingdoms state-owned smart technician Ma Jun, the method of gunpowder wrapped in paper made the entertainment of "explosive battle", created a powder application of precedent. 自秦汉以后,炼丹家用硫黄、硝石等物炼丹,从偶然发生爆炸的现象中得到启示,再经过多次实践,找到了火药的配方。三国时魏国有个聪明的技师马钧,用纸包火药的方法做出了娱乐用的“爆仗”,开创了火药应用的先河。 In the end of theTang Dynasty, gunpowder began to be applied to the military. People use riprap stone projectile machines, fire kits lit after the projectile out, burn the enemy, this is the most primitive artillery. Later, people will head spherical

the great four inventions(四大发明)

Every Chinese will be proud when we mention of the four great inventions. It is absolute that when we mention China's civilization, we think of the four great inventions: papermaking, gunpowder, the compass and printing. The four great inventions are now not only taken as the evidence that the ancient China has got a long history of being civilized, but also the promoter of the development of the whole human being’s civilization. Following we divide the contribution of the great four inventions into 2 parts: culture transmission and new power supply. Before the technology of paper invented, the people had to record some important people and events on sheets which were made of bamboo. And this method of recording was not only expensive but also very inconvenient. So common people were illiterate, knowledge was limited in spreading, which on some aspects caused the low speed in development. After the new technology had invention, it was a very helpful way for people to learn and record. And so did the technology of printing, which made the spread of news and articles much faster and easier. On the other side, the compass and gunpowder both opened a new area of human being. The compass mainly contributed in navigation. And because of communication and trade with people far away, exchanging

四大发明英文

中国古代四大发明英文版 The Four Great Inventions are :The Compass, Gun powder, Papermaking, and Printing. A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation. The magnetic compass is an old Chinese invention probably first made in China during the Qin dynasty (221-206 B.C.). Chinese fortune tellers used lodestones (a mineral composed of an iron oxide which aligns itself in a north-south direction) to construct their fortune telling boards. Eventually someone noticed that the lodestones were better at pointing out real directions, leading to the first compasses. They designed the compass on a square slab which had markings for the cardinal points and the constellations. The pointing needle was a lodestone spoon-shaped device, with a handle that would always point south. Magnetized Needles Magnetized needles used as direction pointers instead of the spoon-shaped lodestones appeared in the 8th century AD, again in China, and between 850 and 1050 they seem to have become common as navigational devices on ships. Compass as a Navigational Aid The first person recorded to have used the compass as a navigational aid was Zheng He (1371-1435), from the Yunnan province in China, who made seven ocean voyages between 1405 and 1433. 2.The Gunpowder [ Pitiful: The western people used the gunpowder to produce weapons, while ancient Chinese used it to make fireworks.] Chinese taoist alchemists were the major force behind the early invention of gunpowder. Emperor Wu Di (156-87 B.C.) of the Han dynasty financed research done by the alchemists on the secrets of eternal life. The alchemists experimented with the sulphur and saltpeter heating the substances in order to transform them. The alchemist Wei Boyang wrote the Book of the Kinship of the Three detailing the experiments made by the alchemists. During the 8th century Tang dynasty, sulphur and saltpeter were first combined with charcoal to
