本文对云南楚雄地区春秋战国时期的一柄防腐较好的青铜矛进行了研究 ,研究发现 ,青铜矛基体的主要成分是铜和锡 ,其含锡量高达 30 .3%;青铜矛表面防腐层的主要成分是 Sn O2 ,高达 83%。研究结果表明 ,Sn O2 具有较好的防腐能力。 In this paper, the better preserved bronze spears of the Spring and Autumn Period and the Warring States Period in the Chuxiong area of ​​Yunnan were studied. The results showed that the main components of the bronze spears were copper and tin with the content of 30.3% The main ingredient is Sn O2, up to 83%. The results show that Sn O2 has good corrosion resistance.
