First, 3d data field was pretreated to a unitary and integral field, and the method of 2d image segmentation was extended and amended, which makes the method be used to segment 3d data field.

该方法先对三维数据场进行归一、整数化的预处理，并修正扩展二维图像的分割方法，使之适用于提取三维数据场边界过渡区。

Then the displacement field in homogeneous medium is considered the result of the first iteration, and the displacement field is solved by this integral equation.

然后，在均匀介质中的位移场被认为是在第一次迭代的结果，和由这个积分方程求解的位移场。
