广州地区出土两汉时期的青铜器大部分都是铜质已完全被腐蚀氧化,器物已毫无铜芯本体的存在,一碰即损,成为一件有形无强度的脆弱青铜器。本文首先根据广州出土脆弱青铜器的物理性质,分类描述广州地区出土青铜器腐蚀状况。然后通过对广州地区的赤红壤含水量、含盐量、含气率、孔隙度、土壤酸性、土壤温度以及微生物等各项因素进行分析,研究广州青铜器在赤红壤条件下的腐蚀机理。
Most of the bronze ware unearthed in Guangzhou during the Han Dynasty was mostly copper that had been completely oxidized and corroded. There was no existing copper body in the utensils, and the bronze ware became a fragile, tangible and strengthless bronze once touched. According to the physical properties of fragile bronze unearthed in Guangzhou, this paper describes the corrosion status of bronze unearthed in Guangzhou. Then, the corrosion mechanism of Guangzhou bronze ware under latosolic red soil was studied by analyzing various factors such as water content, salt content, gas content, porosity, soil acidity, soil temperature and microorganism of latosolic red soil in Guangzhou area.
