The time-distancecurve is a hyperbola when the P-wave is reflected from a 3D dipping interface in isotropic media .
理论上，各向同性介质中三维倾斜界面P波反射时距是双曲线。 在一定。
2
Under certain conditions, the time-distancecurve of reflected P-wave in anisotropic media has similar feature compared with isotropic case.
条件下，各向异性P波反射时距具有各向同性P波反射时距近似的曲线特征。

When the length of CMP is great larger then the depth of the reflector, the information included in the Time-Distancecurve can be used to get the anisotropy parameters of the ti media.
