摘要
利用太赫兹时域光谱技术对几种珍珠粉进行了谱分析。对淡水珍珠粉、贝壳粉及二者的混合物进行了定量测量,建立了混合物折射率与其中贝壳粉质量百分比的回归模型。结果表明,通过回归模型得到的贝壳粉质量百分比与实际含量接近,为珍珠粉检测提供了一种新方法。
With terahertz time-domain spectroscopy, quantitative determination with the pearl powder is analyzed. Having done quantitative determination with the freshwater pearl powder, shell powder and their mixtures, the regression model between the refractive index and the content of the shell powder in the mixtures is established. The results show that the content of shell powder obtained from the regression model is very close to the real one, and it provides a new method for the determination of pearl powder quantitatively.
