对我国主要产于匈奴早期和晚期的16面古铜镜进行了科学考察，得到以下结果：（1）在所考察的16面古铜镜中，除1面镜外，其余15面镜内或镜上均观察到纯铜沉积团块。(2)从测量的和计算的密度得到的密度降低率对应于镜子的腐蚀程度。(3)纯铜块在镜面中的外观形状呈现出多种模式，沉积物像层，大或细颗粒，或沉积物像线或闪电只是毛刺的镜子裂缝。(4)纯铜沉积的环境伴随着由粘土中的腐蚀而发生的金相不规则性。(5)在反射镜中观察到的氧化铜（Cu 2 O）层和颗粒显示出与纯铜沉积物相同的形状。(6)所有铜镜的未腐蚀基体均含有约2质量%的Pb、18 ~ 26质量%的Sn和残余的Cu。
We carried out the scientific investigations of the 16 ancient bronze mirrors produced mainly in the early and the late Hun Era in China, and the following results are obtained; (1) Among the 16 ancient bronze mirrors investigated here, pure copper deposition lumps were observed in or on the 15 mirrors except for one. (2) The rates of density reduction obtained from the measured and the calculated densities corresponded to the degree of corrosion of the mirrors. (3) The shapes of appearances of pure copper lumps in the mirrors show various modes, i.e., depositions like layers, large or fine particles, or depositions like string or flash of lightning just burring the cracks in the mirrors. (4) The environment of the pure copper depositions accompanies the metallographic irregularities occurred by the corrosion in the clay. (5) The oxide copper (Cu2O) layers and particles were observed in the mirrors showing just the same shapes as those of pure copper depositions. (6) Noncorroded matrices of the all bronze mirrors investigated here contain about 2 mass of Pb, 18 to 26 mass of Sn and the residue of Cu.
