摘要
运用扫描电子显微镜、电子探针微量分析、X射线衍射、原子力显微镜和红外反射光谱等分析手段对16块古青铜镜残片的合金基体及表面层进行了分析比较，结果发现表面层内Cu含量低于基体，而Sn．O的含量则明显增高；表面层内有Si元素的富集，并且是以SiO<sub>2</sub>非晶形态存在；对于不同种类的青铜镜，表面层深度不同，含Si量有差异，其表面光亮度和釉质感亦有区别。对古铜镜颜色的变化，SiO<sub>2</sub>的保护作用及铜镜表面的加工工艺进行了分析探讨。
Methods of SEM, EPMA, XRD, AFM and IR-REF were employed to detect 16 fragments of ancient chinese bronze mirrors in the composition and structure of bronze alloy and of the surface layer. It was found that, in the surface layer, there is less Cu but more Sn, O than in the original alloy. It was specially found that in the surface layer there is 5.0-6.6 wt%Si with the structure of uncrystal SiO_2, while in the alloy there is nearly no Si found. For various kinds of bronze mirrors, the deepness of surface layer is different, Si-content is divers, the brightness and the glassiness is distinguishable also.In the present article, the changes in the colour of the ancient bronze mirrors were searched; the protecting functing of SiO_2 was discussed; and the processing technology was infered.
