中文摘要：

利用科学分析手段，对滇西、滇南出土的10件铜器进行了初步的科学分析，包括化学成分分析和金相组织鉴定。结果表明：这些铜器的材质为红铜、铜锡二元合金、铜锡砷三元合金、铅锑砷铜和铜锡铅砷四元合金。体现了滇西地区铜器制作工艺和合金配比的多样化特点，表明了滇西与其他地区青铜文化存在技术交流的可能性。

英文摘要：

The ten samples of metallic artifacts unearthed from seven tombs of Western and Southern Yunnan are examined by the metallographie analyses and SEM-EDS. The SEM-EDS shows that there are Copper, Cu-Sn alloy, Cu-Sn-As alloy, Cu-Pb-As-Sb alloy, Cu-Sn-Pb-As alloy in these tombs. The metallograpbic analyses show that the bronze were made by casting, some which are by forging and cold working after casting. The conclusion is that the bronze culture in this area is diversified and the technique intercommunion exist between Western Yunnan and other areas.
