摘　　要：充分利用岛津电子探针在硬件上的优势,采用全元素测试,即包括超轻元素氧在内的所有元素直接测试的思路对磁铁矿进行了测试,根据电价平衡原则计算出变价元素的含量,并使用状态分析的方法验证了FeO和Fe2O3含量的Lβ/Lα特点,得到了较为理想的测试结果。The magnetite sample was determined by all-elements test method through taking good use of advantages of Shimadzu EPMA(electron probe micro-analyzer)in instrument configuration.In other words,all elements in magnetite including ultra-light oxygen was directly determined.Then the contents of variable valence elements were calculated according to the principle of electric neutrality balance.The characteristics of Lβ/Lαof FeO and Fe2O3 contents were verified by state analysis.The testing results were relatively satisfactory.
