摘　　要：主要通过研究内标元素在电感耦合等离子体原子发射光谱法常量及高含量样品分析中的应用与研究。在分析样品和标准样品溶液中同时加入相同浓度的内标元素,利用强度比绘制标准曲线,求出被测元素的浓度,利用内标的作用,大大改善了白云石、炉渣、烧结矿等常量及高含量组分分析结果的准确度和精密度(提高了近一个数量级);降低基体效应,标准偏差小于0.2%,有较好的长期稳定性,结果满意。This paper studies the adoption of standard elements in the ICP-AES and the constant high level of the sample analysis and research. In the analysis of the sample and standard sample solution at the same time adding the same concentration of the standard elements, rendering the use of strength than the standard curve, obtained measured the concentration of elements, with the use of the subject, has greatly improved the dolomite, blast furnace, sinter, and so constant and High-content analysis component of the accuracy and precision （nearly an order of magnitude）; reduce the matrix effect, the standard deviation of less than 0.2 percent, a better long-term stability, with satisfactory results.
