The study has also shown that there is a rotation angle for azimuthally NMO velocity ellipses in monoclinic media which different form HTI and orthorhombic media. The rotation angles of NMO ellipses are related to the property of fracture infill, fracture density ratio and the angle between the two fractures.

同时，研究表明对于裂隙型单斜各向异性介质，其方位NMO速度椭圆轴向并不象HTI介质和正交介质中的那样与自然坐标系的坐标轴一致，而是发生了一定角度的偏离，其大小与裂隙填充物的性质、两组裂隙密度的比值及裂隙间的夹角等因素有关，研究结果为进一步区分裂隙介质的类型及裂隙填充物的性质提供依据。

As the basis of inversion, we have summarized the overall expressions for Thomsen's parameters and their physical meanings, deduced the expressions of azimuthally varying NMO velocity that usually specifies an ellipse in the horizontal plane for any arbitrary anisotropy, and derived the expressions for the NMO ellipses described by Thomsen's parameters.
