摘　　要：用ＩＣＰ－ＡＥＳ法测定心肌梗塞病人和健康人血中１８种元素含量，把测得结果进行显著性ｔ检验和各元素相关关系的分析，获得不同分类组的相关关系。用模式识别的非线性映射技术对实验数据进行多元分析，得二维映射平面图，判别率达８８．５％～１００％。The contents of 18 kinds of trace and macro elements in blood of normal persons and patients with myocardial infarction were determined by ICP-AES.Some correlation elements were found by using significance test and multivariate analysis.A pattern recognition method for study on relationship between the trace elements and the myocardial infarction was reported, the discriminatory rates are 88. 5 %～100 %.
