The max error point and its value are judged by magneticcurve shape and sur2 vey data error.
通过对磁场曲线形状的处理，测量数据误差计算，判断出最大误差点和数值。

The algorithm is not only effective for the image of front magneticcurve, also effective for image segmentation of other similar histograms.
该算法不仅仅对前磁曲线图像有效，对具有与其相似直方图的图像，均可用该算法进行图像分割。

Unclosed magneticcurve is be build by simulation data of different specification drill pipe, which be used a rule to select optimum magnetization region.
