Combined with the knowledge learned above, what is the relationship between the rule of the Qin and

The Qin and Han dynasties belonged to the decline period of aristocratic rule, and its main personnel were still some aristocratic people to govern the country. After the Qin state conquered the Liangguang region after the Qin attack on the south, the Han Dynasty consolidated the governance of the Liangguang region, and until now, the Liangguang region has been recognized as Chinese territory.

The economy is mainly agriculture, and the productivity has risen greatly due to the extensive use of iron farming tools, and the handicraft industry has also developed rapidly due to the governance of Huang Lao's art in the early period of the Han Dynasty rulers. In order to allow the majestic Emperor Wu of the Han Dynasty to take the initiative to attack the Xiongnu.

Scientific and technological achievements, the invention of the abacus, the knowledge that pi was in between, the compass was greatly used at the time, and the art of papermaking was developed. In fact, another important military invention is the invention of the stirrup.

There is also the politics of the Qin Dynasty is the Legalist ideology in the governance of the country, so the legal system is harsh, the Han Dynasty has just been established after the inheritance of a part of the Legalist thought, to the Han Wen Emperor period, the country needs to restore the national strength, recuperation, so turn to the Taoist Huang Lao's technique, do nothing to rule, and the Xiongnu do not conflict, restore the national strength, to the Han Wu Emperor, the majestic Han Wu Emperor is unwilling to do nothing, and the Xiongnu peace, resulting in several troops to attack the Xiongnu, to protect the interests and security of the country. In the Han Dynasty Emperor Wu accepted the Confucian "depose the hundred schools of thought, respect Confucianism" since then, China's cultural thought has not made major breakthroughs and innovations, and Confucianism does not attach importance to the development of science and technology, resulting in China two thousand years later, in addition to the four major inventions, did not continue to make great contributions to the development of science and technology for the world.

1. The paper industry has been invented and significantly improved.

2. The construction of the Great Wall reflected the development of China's construction technology at that time.

3. Zhang Heng invented the terroir instrument, which is the world's earliest first-class instrument.

During the Qin and Han dynasties, with the consolidation of the feudal system, various ancient Chinese science and technology matured.

China's science and technology history has a long history, China's science and technology, in a long historical period have been in the leading position in the world, the vast scientific and technological achievements, for the development of world civilization has made outstanding contributions.

The greatest achievements are in agriculture, astronomy, mathematics and traditional Chinese medicine, and many scientific and technological achievements such as the "Four Great Inventions" have been born that have influenced the course of world civilization.

Hello. The scientific and technological and cultural achievements of the Qin and Han dynasties are mainly manifested in the following aspects.

China's use of paper as a writing material began in the Western Han Dynasty, Gansu Tianshui Fangmatan unearthed hemp paper is the world's earliest paper, the Eastern Han Dynasty Cai Lun improved papermaking. Papermaking is a great contribution of our country to world culture. During the Eastern Han Dynasty, Cai Lun improved papermaking.

Written in the Eastern Han Dynasty, "Nine Chapters of Arithmetic" is a mathematical masterpiece. Some of the content was at the advanced level of the world at that time.

The geodynamic instrument made by Zhang Heng in the Eastern Han Dynasty is recognized as the earliest instrument in the world.

At the end of the Eastern Han Dynasty, Zhang Zhongjing wrote the book "Treatise on Typhoid Fever and Miscellaneous Diseases", which comprehensively expounded the theory and principles of traditional Chinese medicine, and was respected as a "medical saint" by later generations.

Hua Tuo's creation of the anesthetic "Ma Boiling San" is a pioneering feat in the history of world medicine, and the medical gymnastics "Five Bird Opera" has been compiled.

6. The silk fabrics of the Han Dynasty are exquisite, and the brocade is exported to Rome and enjoys a high reputation, and the Qin and Han dynasties used hand-spinning wheels and jacquard machines.

7. Du Shi of the Eastern Han Dynasty invented water drainage, using hydraulic blast to smelt iron, more than 1,000 years earlier than Europe, which greatly improved the quality of iron smelting.

8. Major development of iron-smelting technology in the Qin and Han dynasties: During the Han and Han dynasties, the "steel frying method" and "100 steelmaking" were invented, and the process smelted high-quality steel and forged sharp weapons.

Reason: The unification of the country, the Qin and Han dynasties were the first unified multi-ethnic country period in the history of our country, and the centralized system was strong, forming a unified situation. During the Qin and Han dynasties, the feudal economy flourished, providing a material foundation for the development of culture.

The fruitful achievements of material and spiritual civilization created in the pre-Qin period provided a solid foundation for the cultural development of the Qin and Han dynasties.

The hard work and invention of the working people provided the conditions for the Qin and Han cultures.

Economic and cultural exchanges among various ethnic groups and regions have been strengthened.

During the Qin and Han dynasties, there was a breakthrough in Sino-foreign exchanges.

I hope the above is helpful to you.

2.Hua Tuo's invention of hemp boiling powder is a pioneering feat in the history of world medicine.

3.Zhang Heng of the Eastern Han Dynasty was the earliest scientific explanation of the lunar eclipse and the invention of the geokinetic instrument.

4.Some of the contents of the Nine Chapters of Arithmetic were at the world's advanced level at that time.

5. Emperor Wu of the Han Dynasty formulated the first relatively complete almanac in China"The primordial calendar"

6. The earliest record of sunspots in the Western Han Dynasty.

7. The Warring States period came out, and the "Yellow Emperor's Neijing" compiled by the Western Han Dynasty laid the foundation of the motherland's medical theory 8. The "Shennong's Materia Medica" of the Eastern Han Dynasty is the first complete work of pharmacology in China.

9,"Medical saint"Zhang Zhongjing's Treatise on Typhoid Fever and Miscellaneous Diseases is an important classic of Chinese medicine in later generations.

Summarize what advanced scientific and technological achievements of the Han Dynasty?

1.In terms of historiography, China's first general history in the form of biographies "Historical Records".

The first chronicle of the Han Dynasty

2.The Han Dynasty was the first time when porcelain firing was invented in China.

3.Han Fu Yuefu, Han ** set up Yuefu to collect folk poetry - that is, Yuefu poems.

4.Science and technology, the creation of papermaking, the development of astronomical instruments, and the flourishing of medicine (the medical saint Zhang Zhongjing completed the "Treatise on Typhoid Fever and Miscellaneous Diseases".

Hua Tuo founded the world's first general anesthesia and appeared in the "Shennong's Materia Medica".

This great masterpiece of pharmacology), mathematical wonders (such as the Western Han Dynasty's "Zhou Ji Sutra".

and the "Nine Chapters of Arithmetic" in the early years of the Eastern Han Dynasty is a masterpiece in the field of mathematics, forming an ancient Chinese mathematical system centered on calculation and completely different from ancient Greek mathematics).

5.Handicraft industry, smelting technology has made great progress (coin casting technology is mature), painting and lacquer craftsmanship is unique (such as the silk book painting unearthed in Mawangdui), and various daily necessities are complete (such as the appearance of the bronze mirror known as the magic mirror.

It also points out the main reasons for the cultural development of the Han Dynasty.

It is the continuous creation of the nation internally and the humble learning of the outside that is the Han nation.

Become an important part of the Chinese nation.

1. Caused by political background. The Qin and Han dynasties were a period of great unification, and powerful political power guided the development of culture and provided a good platform for the development of culture. 2. During the Qin and Han dynasties, the cultural atmosphere was relatively relaxed, except for Qin Shi Huang's book burning and Confucianism, cultural control in other periods was relatively loose.

It wasn't until Dong Zhongshu put forward the three strategies of heaven and man and deposed the hundred schools of thought that Confucianism was dethroned by a hundred schools, and the status of other academics declined slightly, but there were still some among the people. 3. The emperor was more open-minded and advocated cultural development. For example, the three founding emperors of the Han Dynasty advocated the art of Huang Lao, and Emperor Wu of the Han Dynasty respected Confucianism, which provided a good opportunity for the development of these academic schools.

4. Economic reasons. During the Qin and Han dynasties, the economy was quite developed. The Qin Dynasty had many years of accumulation, and it was an economic power during the Spring and Autumn Period and the Warring States Period, so it had the financial resources to support its unification, so that the economic base determined the superstructure, and the culture was also quite developed.

Although the Han Dynasty had limited financial resources at the beginning of the founding of the country, after the rule of Wenjing, it was already strong in the period of Emperor Wu of the Han Dynasty, which also laid the foundation for cultural development. 5. The crystallization of the wisdom of the working people. All kinds of scientific and technological and cultural achievements are inseparable from the creation of the people, this period has emerged a lot of talents, most of the invention experts in the people, powerful only need to organize specialized personnel to collect and manage, you can let these new technology and culture be developed, so as to achieve greater cultural creation.

Impressions: (1) The ancient people of our country were very wise. (2, China.

The nation is a nation full of intelligence and creativity. Scientific and technological achievements: the invention and transformation of papermaking, geokinetic instrument, "Nine Chapters of Arithmetic" "Ma Boiling San". The reasons are (1) national reunification and (2) the strengthening of politics, economy, and culture among various ethnic groups, and the expansion of foreign exchanges.

1 Ideological consent, book burning, Confucianism 2 economic unified currency, rails, weights and measures 3, military north attack, Xiongnu small construction of the Great Wall 4, set the three public local group restrictions.

Papermaking.

1) In the Western Han Dynasty, flocculent paper and hemp fiber paper appeared successively. The paper with a map unearthed in Fangmatan, Tianshui, Gansu Province, is the earliest known paper in the world.

2) Cai Lun, a eunuch in the Eastern Han Dynasty, improved papermaking in 105 to make vegetable fiber paper.

2 Pre-Qin: The Shang Dynasty had the world's earliest records of solar and lunar eclipses. Astronomers in the Spring and Autumn Period left the world's earliest record of Halley's Comet.

The "Ganshi Star Sutra" by Gander and Shi Shen of the Warring States period is the world's earliest astronomical work. The record of sunspots in the Western Han Dynasty in 28 BC is the earliest record of sunspots in the world.

3 Eastern Han Dynasty: Zhang Heng invented the armillary sphere and the geokinetic sphere (more than 1,700 years earlier than Europe).

Mathematical achievement. 4 Eastern Han Dynasty: The Nine Chapters of Arithmetic was the most advanced applied mathematics in the world at that time.

5 Eastern Han Dynasty: Hua Tuo's hemp boiling powder was more than 1,600 years earlier than in the West.

6 Qin and Han dynasties: The Zhou Sutra, written in the first century BCE, proposed a special case of the Pythagorean theorem 500 years before the West.

The reason why China's ancient science and technology can reach a high level: from the perspective of the history of science and technology, there are indeed many discoveries and inventions in China that have had an important impact on the world. So why did ancient China achieve high achievements in science and technology?

In addition to the conditions of our country's vast land, large population, intelligent and industrious people, and the rich experience and knowledge accumulated in the course of long-term struggle against the natural world, a highly centralized unified state has contributed a lot.

Reasons for the achievements of the Qin and Han dynasties:

1. National unity, multi-ethnic cultures can collide and exchange.

2. Encourage folk innovation, and begin to pay attention to sorting out various technologies and documents of the pre-Qin period.

3. The need to resist the aggression of ethnic minorities in the border areas.

4. Economic and technological exchanges with countries in the Western Regions, especially the opening of the Silk Road.

The period of the Three Kingdoms and the Northern and Southern Dynasties.

1. Just like the Spring and Autumn Period and the Warring States Period, all factions want to win in the struggle for hegemony, which prompts them to constantly reform and improve their productivity, so as to win themselves among the heroes.

2. Inherit the unified Qin and Han cultures. Production in the north has developed to a certain extent, and the economy in the south of the Yangtze River has also been developed.

3. Due to the great integration of people of all ethnic groups, the collision of different cultures has led to a spark of innovation and the exchange of Chinese and foreign cultures.
