【#每日跟讀單元 586】科學家解密 兵馬俑兵器永保鋒利之謎
摘要:
he Terracotta Army consists of thousands of life-sized ceramic warriors and horses alongside bronze chariots and weapons, part of the vast 3rd century BC mausoleum near the city of Xian for Qin Shi Huang, first emperor of a unified China. Found in 1974, it represents one of the 20th century’s greatest archaeological discoveries. Scientific analyses almost four decades ago detected chromium on the surface of some of the weapons, spurring the hypothesis that the weapon-makers used a chromium-based treatment to prevent corrosion.
兵馬俑由數千個真人大小的陶瓷兵士和戰馬組成,配有青銅製的戰車和武器,是西安市近郊一處西元前三世紀大型陵墓的一部分,屬於首位統一中國的皇帝秦始皇。兵馬俑在一九七四年被發現,成為二十世紀最重大的考古發現之一。將近四十年前,科學分析在其中一些兵器的表面上偵測到鉻,引發假設,認為製造武器的工匠使用一種鉻為基底的保護膜來防止腐蝕。
