模糊图论在评价人体心脏功能中的应用(英文)

Application of Fuzzy Graph Theory to Evaluation of Human Cardiac Function

为探索用Ｆｕｚｙ图论法评价从事特殊劳动作业人员的心脏功能，研究了两种不同类型的特殊劳动作业人员。第一类３１人，直接用Ｆｕｚｙ图论进行研究，用最大支撑树法进行分类。Ｆｕｚｙ图可分成三部分，分别对应好、较好、最好三种类型的心脏功能。第二类２４人，采用１６个指标，由于指标多，且样本量小，所以先用主成分分析法进行信息提取，综合成６个指标，然后在６个综合指标的基础上，用Ｆｕｚｙ图论进行分析。２４名被试者可分成两部分，分别对应好和较好两种心脏功能状态。两批被试者的分类结果都可在医学上得到可信且令人满意的解释。

To explore the possibility of application of the fuzzy graph theory to the evaluation of humam cardiac function,the cardiac function of two groups of personnel working under special environment were evaluated using the method of fuzzy graph theory. The first group consists of 31 subjects aged 19 ～21 years.They were classified according to their cardiac function evaluated by the method of maximum support tree. While the second group consists of 24 subjects aged 30～40 years and were classified with fuzzy graph theory on the basis of 6 maximum principal components extracted from 16 physiological indices. Medical explanation of the results is convincing.
