What are the important scientific and technological achievements of our country in ancient times?

The wisdom of the ancient Chinese people was very creative, and the main scientific and technological achievements included silkworm raising, bamboo cultivation, iron smelting and iron smelting technology, as well as acupuncture and papermaking guides, acupuncture, geokinetic instruments, water brand porcelain, etc.

Ancient Chinese scientific and technological achievements refer to various scientific and technological achievements in ancient China, including papermaking, printing, textiles, ceramics, smelting and casting, etc.

In ancient China, there were many scientific achievements that are still amazed today, such as papermaking, gunpowder, compass, printing, etc.

An important invention in ancient China included the compass, and Zheng He's voyage to the West was to use the role of the compass to successfully go to the West seven times.

If you want to talk about the scientific and technological achievements of ancient China, the final ones are the four major inventions, that is, papermaking, printing, compass and gunpowder.

There are many, such as the four major inventions, which are known all over the world.

China's important scientific and technological achievements in ancient times include lacquer, jade, silkworm raising, silk reeling, block model method, and bamboo.

Cultivation, tea cultivation, iron and steel smelting technology based on pig iron, branch cultivation (ridge method), bronze crossbow machine, stacking casting method, acupuncture, papermaking.

Chest strap driving method, greenhouse cultivation, jacquard machine, guide car, water mill, new mang.

Copper calipers, fan cars, ground motion instruments, overturned cars (keel cars), water drains, porcelain, stirrups, block printing, shaft rudders, watertight bulkheads, gunpowder, compass (compass.

Dun drilling (well salt deep drilling and drawing technology), movable type printing, water transport instrument elephant platform, double-acting piston bellows, windmills, rockets, fire guns (tubular firearms), human pox inoculation, etc.

1. Iron and steel smelting technology based on pig iron.

The artificial iron products originally used in China were also block iron products, but pig iron smelting technology was invented early on and immediately became mainstream. The earliest known pig iron artifacts are white-mouthed cast iron fragments from the early and middle Spring and Autumn period (c. 8th-7th century BC) excavated from Tianma-Qucun, Yuanqu, Shanxi Province. By the 6th century B.C. at the latest, pig iron smelting technology had developed on a large scale, and more pig iron products appeared in the Jin, Shaanxi, and Henan regions in the middle reaches of the Yellow River and the Wuchu region in the middle and lower reaches of the Yangtze River.

2. Papermaking.

During the Western Han Dynasty (206 BC), China already had papermaking, and in the first year of Yuanxing in the Eastern Han Dynasty (105), Cai Lun.

Improved papermaking, using bark, hemp and cloth, fish nets and other raw materials, through frustration, pounding, frying, baking and other processes to make paper, is the origin of modern paper.

3. Guide car.

Also known as Sinan car, it is a device used to indicate the direction in ancient China. Unlike the compass, which uses geomagnetic effects, it does not use magnetism. A guide car is a simple mechanical device that uses gear transmission to point out directions.

4. Geodynamic instrument.

The geodynamic instrument is Zhang Heng, a scientist of the Eastern Han Dynasty of the Han Dynasty in China.

A masterpiece of creation. There are eight directions of the geodynamic instrument, they are east, south, west, north, southeast, southwest, northeast, northwest, each direction has a dragon head with a dragon ball in its mouth, and there is a toad under each dragon head.

and its counterpart. If there is a ** occurrence on either side, the dragon ball contained in the dragon's mouth in that direction will fall into the toad's mouth, so that the direction of the occurrence of ** can be measured.

5. Rollover (keel car).

Keel car, that is, overturned, a mechanical water lifting tool created by the Chinese working people in the Han Dynasty, a kind of wooden water wheel, the plank with water is connected with a wooden tenon or a ring belt to carry water, and it is mostly rotated by manpower or animal power. It was first recorded in the Book of the Later Han Dynasty and the Biography of Zhang Rang: Emperor Xian of the Han Dynasty.

At that time, Bi Lan "overturned, thirsty for black, applied to the west of the bridge, and sprinkled the north and south suburbs of the road". Most think that it is Ma Jun of the Three Kingdoms.

1. Achievements in the astronomical calendar: The ancient Chinese calendar adopts the lunisolar calendar, that is, the sun's movement cycle is used as the year, the moon's cycle is used as the month, and the leap month is used to coordinate the relationship between the year and the month. According to the changes in the position of the sun in a year and the resulting evolution of the surface climate, the ancients divided the year into 24 segments and listed them in 12 months to reflect the four seasons, temperature, phenology, etc.

The Xia Dynasty calendar was the earliest calendar in China, and the months were determined according to the direction of the handle of the Big Dipper. Xia Xiaozheng, preserved in the "Da Dai Li Ji", is an important document about the "Xia calendar" that exists, and is the earliest astronomical calendar work in China.

2. Papermaking is one of the four great inventions in China, which was invented in the Western Han Dynasty of the Han Dynasty and improved in the Eastern Han Dynasty of the Han Dynasty. Papermaking, especially the papermaking technique improved by Cai Lun in the Eastern Han Dynasty (also known as "Caihou paper"), is a revolution in writing materials, which is easy to carry and widely used, and promotes the cultural development of China, Arabia, Europe and even the whole world.

3. The compass is the result of the long-term practice of the ancient Chinese working people on the magnetism of magnets. As one of the four great inventions of ancient China, its invention has played an immeasurable role in the development of human science and technology and civilization. In ancient China, the compass was first used for rituals, ceremonies, military affairs, divination and feng shui to determine directions.

4. Gunpowder is one of the four great inventions of China. It is a substance that can burn rapidly and regularly under the action of appropriate external energy, and at the same time generate a large amount of high-temperature gas.

In the military, it is mainly used as the propellant of guns and shells, the propellant of rockets, missiles and other driving devices, and is an important part of ammunition. An outstanding achievement in the history of human civilization. Gunpowder has become one of the important inventions of human civilization because of its lethality and deterrence, bringing human beings the role of stopping war and security defense.

5. Printing is one of the four great inventions of the working people in ancient China. Block printing was invented in the Tang Dynasty and was widely used in the middle and late Tang Dynasty. The introduction of printing technology to Europe accelerated the process of European social development, and it provided the conditions for the emergence of the Renaissance.

Marx called the invention of printing, gunpowder, and the compass "a necessary prerequisite for the development of the bourgeoisie." The printing technology invented by the Chinese provided the necessary prerequisites for the establishment of modern society.

1. Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty recorded more than 1,800 kinds of drugs and more than 10,000 prescriptions, which comprehensively summarized Chinese medicine before the 16th century and was known as the "Great Book of Oriental Medicine". Li Shizhen attaches great importance to field investigation and experimental observation, and pays attention to the use of comparative methods, so his understanding and summary of drugs have high scientific value.

2. During the Northern Dynasties, Jia Sixian's "Qi Min Yao Shu" systematically summarized the experience of agricultural and animal husbandry production, food processing and storage, and the utilization of wild plants in the middle and lower reaches of the Yellow River before the 6th century, which is the earliest and most complete agricultural book in China.

3. During the Warring States Period, the handicraft monograph "Examination of Work" appeared. It describes the design specifications and manufacturing processes of various types of work in the official handicraft industry of Qi State, which not only has an important position in the history of the development of engineering in China, but also is unique in the world at that time.

4. Song Yingxing's "Heavenly Creations" in the Ming Dynasty summarized the production technology of agriculture and handicrafts in the Ming Dynasty. The book also includes some technologies that have been transmitted from abroad, which shows that the continuous introduction of overseas technologies has become indispensable knowledge for people. Abroad it is called "the encyclopedia of Chinese craftsmanship in the 17th century".

5. The Northern Song Dynasty scientist Shen Kuo's "Mengxi Writings" summarized many scientific and technological achievements in ancient China, mainly in the Northern Song Dynasty, and has an important position in the history of science and technology in China and the world.

1. The invention of the compass (originally called the compass car) played a very important role in determining the direction of the world's navigation.

2. The smelting technology of bronze has enabled human beings to enter the Bronze Age from the Stone Age, which has greatly improved productivity.

3. The invention of papermaking and printing has promoted the development of world culture.

4. Zhang Heng invented the armillary sphere and the geokinetic instrument, which improved the ability of human beings to observe astronomy and observation.

5. The invention of gunpowder has improved the ability of human beings to transform nature and promoted the development of productive forces.

6. China has long had the production of pottery and porcelain, which has promoted the development of food culture.

1. During the reign of Emperor Wu of the Han Dynasty, astronomers formulated China's first relatively complete almanac, the Taichu Calendar, and began to start with the first lunar month.

The "Taichu Calendar" divides a day into eighty-one points, so it is also called the "eighty-one points legal calendar". It is a relatively complete calendar in ancient China, which is an epoch-making progress in China's calendar. At the beginning of the Han Dynasty, the Qin system was inherited, and the ancient calendar "颛顼 calendar" was used, and the "Taichu Calendar" and "颛顼 Calendar" were comprehensively compared, and there was a significant progress.

2. During the Warring States Period, the world's earliest astronomical work "Ganshi Xingjing" appeared, which has rich astronomical records, reflecting people's understanding of astronomy during that period.

The Ganshi Xingjing is an astronomical monograph, with eight volumes each of the Ganshi and Shijing, a total of 16 volumes, which was roughly written in the Warring States Period. "Ganshi Xingjing" is the joint name of the two books, and the authors are Gan De, a native of Qi at that time, and Shi Shen, a native of Wei.

3. In the Eastern Han Dynasty, Zhang Heng made the earliest scientific explanation of the lunar eclipse from the different positions of the sun, moon and earth.

4. The ground motion instrument invented and produced by Zhang Heng can telemealy the direction of occurrence thousands of miles away, more than 1,700 years earlier than Europe. The geodynamic instrument is a masterpiece created by Zhang Heng, a scientist of the Eastern Han Dynasty of the Han Dynasty in China. There are eight directions of the geodynamic instrument, they are east, south, west, north, southeast, southwest, northeast, northwest, each direction has a dragon head with a dragon ball in its mouth, and there is a toad corresponding to each dragon head.

5. The "Great Calendar of the Great Calendar" formulated by the astronomers and monks of the Tang Dynasty accurately reflected the laws of the sun's movement and was well-systematic, indicating the maturity of the ancient Chinese calendar system.

The Great Yan Calendar, also known as the "Kaiyuan Great Yan Calendar", was implemented in the 17th year of the Tang Dynasty (729 AD) for 29 years. One line. It is named because the legislation is based on the number of "Yi" elephants.

A line of measurement of the latitude of each place, south to Jiaozhou to the north of Tiele, and step nine sundials, set the eclipse score of each place, and re-measure to see the movement of stars.
