Note: it may be impossible to measure the "true" standard deviation.

注意：不可能测量出“真实的”标准偏差。

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。
