摘　　要：文章旨在研究热处理对茶晶颜色的影响及茶晶的致色成因。通过选取市场上常见的茶晶样品进行热处理实验、放大观察、红外光谱以及紫外-可见-近红外分析测试,记录茶晶的颜色变化,结果表明热处理可以改变茶晶的颜色;对比茶晶在热处理前后的颜色和光谱变化,证明茶晶是色心致色。This paper aims to investigate the effect of heat treatment on the color of brown quartz and its color genesis.After selected from the market,the brown quartz samples were subjected to heat treatment experiments,magnification observation,infrared and UV-VIS-NIR spectroscopic tests.Color changes of the samples during heating experiments were observed and recorded.By comparing the color and spectra of the samples before and after heat treatment,it is proved that the color genesis of the brown quartz is irradiation induced color center.
