用Ｘ－射线衍射、等离子发射光谱法对来源于九个不同产地的矿物药禹余粮作了较为全面的分析与研究。给出了定性、定量相分析的宏观结果以及微量元素及晶粒尺寸的微观数据。测试结果表明：该矿物药主要由针铁矿、赤铁矿、石英及粘土矿组成。粘土矿的种类与含量、晶粒大小以及与人体健康有关的微量元素的含量随药物来源而异。根据测试结果还对该药物进行了初步评价和讨论。 X-ray diffraction and plasma emission spectroscopy were used to analyze and study the mineral medicines from the nine different production areas. The macroscopic results of qualitative and quantitative phase analyses and the microscopic data of trace elements and grain sizes are given. The test results show that the mineral medicine is mainly composed of goethite, hematite, quartz and clay minerals. The type and content of clay minerals, grain size, and trace elements associated with human health vary with the source of the drug. According to the test results, the drug was also initially evaluated and discussed.
