Calculating formula of wave impedance is obtained by main values of the inverse tangent function of phase_shift at two neighboring frequencies and the corresponding integral character of phase_shift is denoted as the convergent criterion of wave impedance inversion.

利用复合反射系数中多个频率点的相移反正切函数主值，给出了波阻抗的计算公式，并把套管-地层环空间介质中波的相移的整、实特性作为波阻抗反演收敛的判据。

In addition, this article took the isoclinic information which unwrapped already into isochromatic formula to get the correct retardation. This method might not get the form of arc-tangent because there are not output quarter-wave plates in three and six phase-stepping methods. Therefore, this paper corrected it by load-stepping method.

另外，为了使相位展开技术能顺利完成，进而得到相对的延迟量，在修正等色线包裹相位图中的不连续点时，本文使用之方法是将修正完的正确等倾线数值带入等色线公式中，此法在三场与六场中因为少掉了输出的四分之一波板，造成公式的结果使得条纹角度分布非反正切形式，因此需另外使用负载相移法来做修正。
