Abstract：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.
