为研究古哀牢地区青铜器的制作工艺，对若干滇西保山一带出土的战国到西汉时代的铜剑进行了取样，并采用金相显
微镜和扫描电镜进行分析，研究结果表明：这些剑的材质均为铜锡合金，制作工艺分铸后冷加工和热锻后冷加工两种。其中，经铸后冷加工的一把剑的刃部还采用包铁工艺，其外形与其他剑相比也有相当大的差异，说明这些青铜剑有迥然不同的制作工艺，是不同时代或不同民族工匠的制作产品。对研究古哀牢地区的金属技术及其与周边地区的技术和文化交流有一定的价值。
In order to study the production process of the bronzes in the ancient Ailao area，several samples of bronze swords from Warring States to the W estern Han Dynasty were selected，which were unearthed in the Baoshan，western Yunnan．The samples were analyzed by the metallographic microscope and SEM．The results showed that these swords were made of copper—tin alloy，and the production processes were classified in two types：cold working after casting and cold working after hot forging．Coated iron process was utilized in one sword produced by cold working after casting，the shape of this sword was much different from the others，which means that the production processes of the bronze swords varied widely and the swords belonged to different periods and different ethnic artisans． This paper was valuable for the study of metal technology in ancient Ailao area and the technical and cultural exchanges of ancient Ailao area with surrounding areas．
