Intrusion detection methods based clustering are based on distancedifference, but to depend on the similarity measurement of all attributes in the same degree tend to arouse misleading.
基于聚类的入侵检测方法大都是以距离差异为基础的，而同等重要地依赖所有属性的相似性度量会引起误导。

We propose two methods of similarity measurement: entropy differencedistance measure(ED) and maximum relative entropy distance measure(MRE) .
提出了两种基于信息嫡的相似性度量方法：嫡差分距离度量和最大相关嫡度量。

A formula of height difference precision for remote distancemeasurement by total station is derived in this paper. The influences on the height difference precision are analyzed and calculated.
