| 摘 要： | 通过肉眼和显微镜观察，采用比重法、硬度法、X射线衍射法、红外光谱法、激光拉曼光谱法等无损仪器检测法对122件薛家岗出土玉器进行了玉种鉴定，探讨了玉器的物理性质和结构特征，并提出了出土古玉器的保护问题。分析结果表明，肉眼鉴别风化严重的古玉器，误判几率较大；彻底排除玉器内空气的影响，比重法分析可准确判定严重受沁古玉器的物相组成；古玉器内部与表层在颜色、致密度等存在差异，但主要物相组成相同。 |

| Abstract: | Through observing with naked eyes and microscope, measuring with some analytical techniques such as gravimetry, hardness test, X-ray diffraction analysis, Fourier transform-infrared spectrometry and laser Raman spectrometry, 122 pieces of ancient jade samples excavated from Xuejiagang site were identified. The physical features and structural characteristics of jades were also discussed. Furthermore, the proposals on protection excavated jades were put forward. The analytical results indicate that the probability of misjudgemment for the ancient jades under serious weathering with naked eye testing is much higher than with other methods. If the influence from air within the samples could be thoroughly eliminated, the components of the ancient jades can be precisely distinguished by gravity test. Although there are differences in color, density and etc. in inner and outer surface of the ancient jades, principal phase compositions are identical. |
