The four great inventions
Paper: paper is an important chemical processes, the invention of paper is Chinese in the spread of human culture and development make a valuable contribution, is China's chemical history of a major achievement.
The paper also before, oracle bones, bamboo slips and silk silk is used for writing, the ancient recorded material. But due to the rapid development of the economy, culture, bones and bamboo can not meet the demand of development, thus contributing to the improvement of writing tools. At that time people began using small silk made of paper, as the ancient Chinese when paper by hemp thread and silk, and preparation method of rough paper, so the quality is not so good. But the hemp thread and silk has its own role, to use them as a raw material for paper-making, would be greatly restricted, and difficult to get rapid development, to meet the cultural life of the requirement to paper.
In the new situation request, Cai Lun of Eastern Han Dynasty for the emergence of papermaking to bring new breakthrough in the Eastern Han Dynasty," views on" 2 records:" Cai Lun, talented, dedicated to cautious, every vacation, closed to the guest, aeration body field. Code for the sale, made with bark and spacious cloth, net to make paper. Xing Yuan first year playing, the emperor can, since is not used, the salty called Cai Hou paper". From above, Cai Lun is using bark, rags, net of papermaking. Although before Cai Lun also has a paper, but raw material itself is very limited, and Cai Lun on the new raw materials, to solve this problem. Because the rag, broken fishnet had already finished their task, a waste and used as a raw material for papermaking industry, which plays an important role.
Printing: is the working people in ancient China through long-term practice and research before the invention of. About the year before and after 600 years of Sui Dynasty, people from the engraved seal inspired, in the history of mankind's earliest invention of woodblock printing.
Woodblock printing is in a certain thickness of the smooth wood, paste copy neat manuscript, thin and almost transparent paper front and wood paste, the word became the body, strokes clear. Engraving workers graver in the suites have writing section is cut away, is a convex embossed font, and font recessed beneath the different steles. When printing, on a raised fonts with ink, and then the paper covering on top of it, gently wipe away the paper back, writing remain on the paper. By the Song Dynasty, woodblock printing career development to the heyday. Woodblock printing on the spread of culture play an important role, but also has obvious disadvantages. The first version, time-consuming material costs, second, a large number of books stored inconveniently, third, is not easy to correct mistakes.
The Northern Song Dynasty civilian inventor Bi Sheng invented movable-type printing, woodblock printing these drawbacks improvement. Bi Sheng's Dynasty of an ordinary civilian intellectuals, the person who. He summed up the block printing of rich experience in practice, after repeated tests, the emperor Renzong of evolution years (AD 10411048 ) made the moveable, execute typesetting printing, completed the printing history of a major revolution, about 200 years later, this technology spread to other countries, the development of world civilization process to promote the role of.
Gunpowder: is one of the four great inventions of china. Gunpowder, as the name suggests is the ( fire medicine ). Its origins and alchemy are closely related, Bachelor in ancient alchemy alchemy inadvertently material.

Gunpowder itself is also come under the drug class, the Ming Dynasty Li Shizhen ( compendium of Materia Medica ) said, gunpowder can cure sore ringworm, insecticidal, provide moisture and plague. The invention of gunpowder is a long-term alchemy pharmaceutical practice results, has been one thousand years of history.
The Tang Dynasty, gunpowder has been used for military. The Song Dynasty, the war continuously, promote the accelerated development of gunpowder weapons. The government of the Northern Song Dynasty established a powder mill, has made gunpowder arrow, artillery and other combustion properties mainly weapons and ( bang cannon ), ( lightning bombs ) and other explosive strong arms. The Southern Song Dynasty were created in 1259 to giant bamboo tube, built-in gunpowder ( sudden guns ). To the Yuan Dynasty and the emergence of bronze ( copper Fire Commission, known as the general). These are to gunpowder explosion as the driving force of arms, in the war revealed a hitherto unknown power.
In 12, thirteenth Century, the gunpowder first introduced in Arabia state, and then spread to Greece and Europe and around the world. On the civilization and progress of human society, the economy and the development of science and culture, played a role in promoting. The law until the middle of the fourteenth Century, only then has the application of gunpowder and firearms records.
Compass : the spring and Autumn period, Chinese working people in the mining, smelting, gradually recognized magnet. To the Warring States period, some people use magnets made apparatus to determine the direction, then called" compass", it is in a along the plate placed on a water scoop like magnet, water scoop handle end of South point. To the late Northern Song Dynasty ( Eleventh Century AD), the Chinese people have created artificial magnet, then created a" guide to the fish", the magnet." Fish" on the water surface, thus indicating the direction. Later, after repeated research and improvement, and the magnetic steel sheet into a small magnetic needle, and makes its tip into the magnetic north pole, end become the south magnetic pole, which became a compass. The Northern Song Dynasty, people create a suitable nautical compass, the maritime industry to a new era. During this period, China 's shipbuilding technology in the world the most advanced. At the beginning of the fourteenth Century, the compass was introduced into Europe from china.
全世界专利的40%都可以在中国科技史找到原型。四大发明，算什么！可惜，那些专利都不是中国的。为什么？
大自然的启示是无穷无尽的，它给我们带来的发明创造也是数不胜数。潜艇的设计灵感来源于鱼类，人们模仿鱼类的形体造船，使潜水艇成为了可能。雷达的发明则源于对蝙蝠的观察，它能够像蝙蝠一样发射和接收超声波，探测目标。
鲁班的故事更是说明了这一点。一次上山砍木时，鲁班被一种带齿的草割伤了皮肤。从这带齿的草中，他受到了启发，发明了竹锯。这种简单却实用的发明，极大地提高了砍伐效率。再如，通过对水中生活的鱼类的模仿，人类发明了潜水艇，使人类能够深入海底探索。
青蛙的眼睛也给了人们启示。电子蛙眼就是模仿青蛙的眼睛发明的，它能够准确地捕捉目标，用于军事、安防等领域。
这些例子都告诉我们，大自然是人类智慧的宝库。我们应当学会从自然中获取知识，应用知识，发明更多的东西，为百姓造福。每一次对自然现象的观察，都可能激发新的灵感，带来新的发明创造。
1. 四年级我的发明350字作文
我想发明的机器人有许多功能,它可以植树造林、吸收废气放出清新空气、把垃圾变成电等。
机器人的第一个功能就是植树造林。机器人会去大沙漠种上数不清的绿树绿草。一旦这样,就是大沙漠也会变成绿洲;机器人的第二个功能就是把废气吸收到体内,放出清新空气。这样一来,世界的废气就几乎没有了,而清新空气会非常多;机器人的第三个功能就是用它的“吸收垃圾器”把垃圾吸收到自己的身体里,再转化成电,造福人类;机器人的第四个功能就是去山上挖宝藏,送给穷人,一旦这样,穷人就不会没钱用了;机器人的第五个功能就是进入人类的身体里,把细菌消灭,这样一来,人类的身体就会很健康了;机器人的第六个功能就是当你爸爸妈妈不在的时候,给你当全自动保姆;机器人的第七个功能就是……
这就是我做的机器人,完美吧!如果叫小朋友你来做一个机器人,你会这么做呢?
2. 四年级我的发明350字作文
今天,我看到桌子,我就想发明多功能的桌子。
这种神奇课桌它可以帮你做许许多多的事。如果你的橡皮檫不见了,你想找回来就按按纽,镜子里会根据你刚才的情形出现了橡皮,你想去拿,没关系,桌子会马上伸出两只“手”帮你拿起来。
神奇的书桌还会叮嘱你。
In the world, there are many brilliant inventions, such as the Internet, computers, cars, airplanes, etc. Without them, our lives would be difficult and boring. Therefore, I believe that the greatest invention is the one that brings convenience and happiness to people.
以上就是关于发明的作文的全部内容，我的小发明作文300字（篇1）：今天，我在家中写作业时，发现橡皮擦出的屑不仅弄脏了作业本，还容易飘得到处都是。这让我想出了一个主意：设计一个能处理橡皮屑的小发明。经过一番思考，我决定仿照笤帚和簸箕的原理，制作一个“橡皮屑收集器”。我首先在橡皮的一端凿了一个小孔，内容来源于互联网，信息真伪需自行辨别。如有侵权请联系删除。
