我国是世界文明发达最早的国家之一。在铸造技术上有着悠久的历史,是世界上应用铸造技术最早的国家之一。据考古发现,在我国江西万年县大源仙人洞洞穴遗址中,曾出土一评夹砂红陶片,经放射性碳14测定,其年代数据为10870±240年。这证明早在一万多年前,我国已经有陶器的制作。陶器业的不断发展,就对金属铸造产生影响。根据考古发掘,在甘肃东乡林家马家窑出土的一批铜器,用C_(14)测定其年代为公元前2740年,证明我国在五千多年前已使用了铜器。三千年前的殷商时代,我国用泥型铸造出
Our country is one of the earliest developed countries in the world. Casting technology has a long history, is the world’s casting technology, one of the earliest countries. According to archaeological discoveries, in our country Jiangxi Wannian County Danyuan immortal cave site, has unearthed a review of sandstone, measured by radioactive carbon 14, the age of 10870 ± 240 years. This proves that as early as 10,000 years ago, China has been the production of pottery. The continuous development of the pottery industry has an impact on the metal casting. According to archaeological excavations, a group of bronzes unearthed at Majiayao, Dongjiale, Dongxiang, Gansu Province, using C_ (14) dating from 2740 BC proved that copper was used in China more than 5,000 years ago. Three thousand years ago Shang period, our country with mud casting out
