In Chinese history, Qin Shi Huang is undoubtedly a pivotal figure. He was not only the first emperor of feudal society, but also the founder of the completion of great unification. However, after his unification, the Qin Dynasty quickly declined in the Chu-Han dispute. Today, it has been more than 2,000 years since the death of Qin Shi Huang, and the only thing left for future generations is the Mausoleum of Qin Shi Huang, which has witnessed its prosperity and decline. Among them, the most striking is the arrowhead used in the terracotta warriors, which represent the astonishing manufacturing technology of the ancient Qin Dynasty.
Amazing ancient manufacturing power, arrows hidden black technology!
The level of technology displayed by the terracotta warriors and horses can be described as the pinnacle of ancient times, especially the arrowheads used by Qin crossbows. Through careful observation and analysis, the researchers discovered that the craftsmanship of the arrow is amazing. After magnifying it by 80 times, the shape and characteristics of the arrow show the exquisite level of manufacturing at that time.
First of all, the arrow is designed with a triangular prismatic shape, which perfectly conforms to the laws of aerodynamics and has the characteristics of stable flight, accurate strike and strong penetration. At 20x magnification, the length of the three ridges of the arrow is extremely accurate, with a difference of only 002 mm-0between 55 mm. Such precision is difficult to achieve in today's machinery manufacturing, demonstrating the superb craftsmanship level of the Qin Dynasty.
Secondly, the blade of the arrow head is even more breathtaking. After magnifying 80 times, the scratches on the blade show a beautiful pattern that is orderly and staggered. These fine grinding marks demonstrate the highest level of craftsmanship at the time, and are even more sophisticated than modern machine building. This precise grinding process can only be completed by rotating the grinding wheel by a machine, which shows the depth of the craftsmen of the Qin Dynasty in this regard.
Thirdly, the metal proportions of the arrowhead are also breathtaking. The arrow collar part is poured with molds, and the main material is bronze, but the tin content in the arrow is 20%. This metal alloy technology was mastered by the Qin Dynasty more than 2,000 years ago, showing its high attainment in metal smelting. Such technology played a crucial role in the military superiority of the time.
Behind the exquisite craftsmanship of arrowheads, the ancients have already mastered "black technology"!
In addition to the shape, blade and metal proportions, the study also found that the arrowheads excavated from the terracotta warriors were oxidized with chromium salts, and a chromium oxide antiseptic layer of about 10 microns was formed on the surface. This discovery shows that the ancients had mastered the standard process of the casting process in the production process of arrowheads. This makes the arrow arrowhead still bright as new after being buried deep underground for thousands of years, showing the level of anti-corrosion technology at that time in the Qin Dynasty.
Overall, the craftsmanship of the terracotta warriors and arrows shows the world the outstanding achievements of the Qin Dynasty in terms of manufacturing power and scientific and technological level. This kind of excellence, precise technology, and strict standards of production still has enlightening significance for today's enterprises and manufacturing industries. The "black technology" and "high technology" of the ancient Qin Dynasty were not only the advanced level in the world at that time, but also a vivid scientific and technological feast for future generations.
Epilogue. 
A simple arrowhead, behind which contains ancient "high technology", makes people can't help but admire the manufacturing level of the Qin Dynasty. It is also a reminder of modern society that technological progress stems from the continuous pursuit and innovation of manufacturing processes. The exquisite craftsmanship of the terracotta warriors and horses is the treasure of ancient civilization and the crystallization of the wisdom of the Chinese nation for thousands of years. Perhaps, in the process of exploring history, we can find more ancient "black technology" to provide more enlightenment for today's scientific and technological development.
The ancient miracles displayed by the craftsmanship of the terracotta warriors and arrows are undoubtedly breathtaking. This article reveals in detail the level of manufacturing and scientific and technological achievements during the Qin Dynasty, giving us a deeper understanding of the high development of ancient civilizations.
First, through an analysis of the shape, design, and metal proportions of arrowheads, the article demonstrates the extraordinary craftsmanship of the craftsmen of the Qin Dynasty in terms of manufacturing techniques. The triangular prismatic design of the arrow not only conforms to the laws of aerodynamics, but also makes modern machinery manufacturing unmatched in terms of precision. This shows that the level of craftsmanship in the ancient Qin Dynasty has reached an extremely high level, and even surpasses it. This craftsmanship and extreme pursuit of detail is the treasure of ancient civilization, and it is also worthy of deep thought in today's manufacturing industry.
Secondly, the article's detailed observation of the blade of the arrow head is even more amazing. By magnifying the image 80 times, we can see the staggered scratches on the blade of the arrow, demonstrating the highest level of craftsmanship at the time. This kind of precise grinding marks, and the meticulous technology required, are difficult to fully replicate even in today's technologically advanced era. This has led to a deep reflection on ancient manufacturing processes, and at the same time reminded that the pursuit of exquisite craftsmanship in modern manufacturing cannot be ignored.
Third, the article emphasizes the metal proportions of the arrowheads, highlighting the Qin Dynasty's mastery of the high technology of metal smelting. The pouring of the mold and the rational configuration of the tin content of the bronze arrow collar show the excellent level of smelting technology at that time. This was not only for the manufacture of arrowheads, but also played an important role in the Qin Dynasty's superiority in the war. The achievements of ancient craftsmen in metal smelting provide a valuable reference for today's materials science.
Finally, the article points out that the anti-corrosion treatment of arrowheads is also an outstanding representative of the technology at that time. The formation of the chromium oxide antiseptic layer shows that ancient craftsmen had mastered a set of standard casting processes. This treatment allowed the arrowheads to remain as bright as new after being buried deep underground for thousands of years, showing the high attainment of the craftsmen of the Qin Dynasty in antiseptic technology.
In general, this article provides an in-depth and comprehensive analysis of the production process of terracotta warriors and arrows, allowing us to deeply appreciate the glory of ancient civilizations. It is not only a praise for the ancient level of science and technology, but also a revelation for modern manufacturing. We should cherish and learn from the spirit of ancient craftsmen to promote the innovation and development of today's manufacturing industry. Such a historical review undoubtedly provides us with more space for thinking and **.
