| 摘 要： | 针对包含多种类型属性的复杂数据对象在比较时的难题，给出了它们之间的一种比较方法．该方法引入了相似度的概念，给出了相应的复杂对象相似度的计算方法．该方法使复杂对象不同属性的类型和取值范围差异对比较结果的影响减小，使得比较简单化，便于常规排序算法的应用。

| Abstract: | A method of comparison among complex data objects that involve multiple attributes is presented. The method is based on the concept of similarity. In the meantime a method of computing the similarity of complex objects is presented, which reduces the influence of multiple attributes for the comparison results and is thus feasible for applications in conventional algorithms. |
