摘　　要：滑石是一种十分重要的中药矿物药,其质量检验对于人体健康和环境至关重要。本文提出的以电子探针为主、并辅以X光衍射分析等方法的滑石质量检验途径,是一次新的探索。正是由于电子探针可以同时进行高倍图像观察和定性定量分析,对滑石中的杂质分析灵敏度更好,其检测结果也更直观易懂。Tacl is an important mineral medicine in traditional Chinese medicine,the quality inspection of which is important to human health and environment.In this paper,a new method was proposed for the quality inspection of talc by using electron probe assisted by X-ray diffraction.Beacuse electron probe analysis can conduct image observation with high magnification,and conduct qualitative and quantitative analysis at the same time,so its testing results are more intuitionistic and much easier to understand.
