| 10. | Can influence directly the velocities of compressive wave and shear wave of rock . commonly , the higher the content of carbonate in rock , the higher the velocity of compressive wave and shear wave ; the higher the mud content , the lower the velocity of compressive wave and shear wave ; the higher the porosity of rock , the lower the velocity of compressive wave and shear wave ; the more compacted the rocks , the higher the velocity of compressive wave and shear wav
6 )岩石组成和孔隙度等岩石内部因素均可直接影响岩石的纵横波速度，一般说来，岩石中碳酸盐含量越高，其纵横波速度越高；而泥质含量越高，其纵横波速度越低；岩石孔隙度越高，其纵横波速度越低，岩石密度越大，其纵横波速度越高。 |
