The low-frequency limit in the parallel orientation was higher than that in the perpendicularorientation;
平行方向的低频极限量高于垂直方向的低频极限量；
2
The high-frequency limit of relative permittivity was the same in the parallel and the perpendicularorientation;
平行方向和垂直方向的介电常数高频极限量相等；
3
The orientation of the induced hydrofractures arc controlled by the mutually perpendicular orientations of the maximum and minimum principal stress components of in situ stress field.
