The abnormal area delineated by using this method is smaller than that delineated by the standard deviation and isoline methods, characterizing the true anomalous boundary.
利用文中方法圈定出的异常面积比采用标准方差与等值线圈定异常方法小，表征了真正的异常边界。

Assume that there is an equivalent node on each side of a grid when using gridding method to draw isoline, how to connect these nodes is ambiguous.
在采用网格法追踪等值线时，如果某个网格四条边上都有等值点，等值点的连接就会出现多义性问题。

This paper presents a basic principle of making network processing, following the trail of isoline, and smoothing curves by near-point average weighting method.
