摘　　要：目的 :研究松风HOLO技工比色板各组各色阶颜色分布的规律性。方法 :采用数码摄影和计算机技术对松风HOLO技工比色板的不透明瓷、颈部瓷、透明瓷进行测量 ,通过L -C平面图及a-b散点图分析。结果 :测定数据表明比色板各组颜色分布具有一定的规律性 ,不同组相同色阶比色板彩度C排列顺序为 :颈部瓷 >牙本质瓷 >不透明瓷 >透明瘊 ,但就占有的颜色分布区域而言 ,牙色的主要因素。同组不同色阶的确彩度之间差距较明显 ,肉眼较容易区分不同色阶比色板 ,因此技工行烤瓷冠颜色的修正时 。Objective: The purpose of this study is to reveal the ordering of color range in Shofu Holo technical shade guide of different color stage on each group. Method: Applying the method of Digital-photo and computer, measures shade guides of porcelain powders in opaque, body, cervical, incisor translucent and analyzes it through L-C plane illustration and a-b scatter-dot illustration. Results: There is logical order of color range in Shofu Holo technical shade guide. The arrangement in order of chrome in different group of the same color guide class is cervical>body>opaque>incisor translucent. So far as color region is said that occupying area is cervical>body>opaque>incisor translucent.
