摘　　要：选取表面光泽柔和的永子黑子(YZ-1)和白子(YZ-2),经清洗干燥预处理后,开展永子的显微特征与拉曼光谱分析。结果表明:YZ-1和YZ-2在显微特征上的主要差异为主体部分非规则样条曲线成像形式。YZ-1在3个测点上其散射峰基本一致,共有7个独立散射峰,包含各分子键的对称/非对称伸缩振动、ʋ_(s)(T-O-T)型振动、弯曲振动、旋转振动、平移振动等;YZ-2本身有荧光,而没有较强的拉曼响应,且其荧光强度强过拉曼光谱仪检测限,发生尾部上飘,在测点point 1上波长518 cm^(-1)和411 cm^(-1)处散射峰可能为在Si-O-Si键对称伸缩-弯曲振动。The microscopic characteristics and Raman spectra of the black pieces(YZ-1)and white pieces(YZ-2)of Yongzi chess were analyzed after cleaning and drying.The results show that the main difference between YZ-1 and YZ-2 in microscopic features is the irregular spline imaging form of the main body.The scattering peaks of YZ-1 at the three measuring points are basically the same,and there are 7 independent scattering peaks in total,including symmetric/asymmetric stretching vibration of each molecular bond,ʋ_(s)(T-O-T)type vibration,bending vibration,rotating vibration,translation vibration,etc.YZ-2 itself has fluorescence,but there is no strong Raman response,and its fluorescence intensity is stronger than the detection limit of the Raman spectrometer,and the scattering peak at wavelength 518 cm^(-1) and 411 cm^(-1) at the measurement point 1 May be symmetric stretching-bending vibration at the Si-O-Si bond.
