摘　　要：DiaShape系统是一种通过光学手段快速进行金刚石晶体品质检测的方法 ,目前国内外已有部分应用。本文实验选用国内两个厂家的金刚石产品 ,包含从SMD到RVD1的全部系列 ,通过对试样的光学图像采集 ,结合DiaShape系统中关于晶体形貌和光学性质的定义 ,测得试样的晶体纯净度 ,并按标准的方法 ,分别测出金刚石单晶的抗压强度。经过对比可以看出 :随抗压强度的下降 ,晶体的纯净度有下降的趋势 ,但表现规律性不强 ;通过对理想晶体模型的计算 ,本研究找出了晶体纯净度在定义上的不足并提出了一种可能的解决方案。DiaShape system is an accurate and quick method to check up the quality of diamond crystal. In this paper, serials diamond crystals(SMD～RVD1) selected from two famous domestic factories were used as specimens, and the crystal clarity value was obtained by collecting optical pictures combined with the definition of crystal appearance and optical parameters in DiaShape System. According to the national standard, the compressive strength of the specimen diamonds was measured. The results from comparison showed that there is a decreasing trend for the crystal clarity with the compressive strength decreasing, but which is not always regular. It is found by calculation about ideal crystal model that the existing definition of crystal clarity has some shortcomings, and a feasible solution is put forward.
