【摘要】 八三玉是我国近年出现的一种新品玉石 :主要成分是硬玉 ,其次有少量辉石族矿物和闪石族矿物 ;显微结构以粒状镶嵌变晶结构为主 ;颜色与翡翠十分相似 ,而实质上又有差异。本文对八三玉的透明度及其决定因素进行了色度学研究。半定量计算分析认为 :八三玉为不透明 -半透明的玉石 ;主波长约 485nm ,刺激纯度 0 .38左右 ;颜色主要以反射光谱为主 ,兼以吸收光谱和透射光谱更多还原

【Abstract】 BaSan Jade is a kind of new jade, which has been appeared in China in recent years. It’s main mineral is jadeite with some amphibole and pyroxene. The main character of texture under microscope is granular blastic texture. The color of it is similar with jadeite jade very much, but they are different of essence. This article has done some research work of colorimetry about the transparency and its determinative factors of BaSan Jade. After semi quantitative analysis, we know that BaSan Jade is translucene opaque, its main wavelength is 485 nm or so, and stimulatory purity is about 0.38. The color of Basan Jade is mainly reflective spectrum, and then transmitting spectrum and absorbed spectrum.更多还原
