具体地说，任何给定对象的MRO(相对于某个特定方法)仅仅是class属性(如果有的话)中的命名类向量。

Specifically, the MRO of any given object (relative to a particular method) is simply the vector of named classes, if any, in its class attribute. For example.

以扫描向量中的属性频率项作为属性约简搜索的启发信息，提高了属性约简效率。

The item of attribute frequency in the scan vector was taken as heuristic information to improve the efficiency of attributes reduction.
