By　measuring　the　velocity　of　the　P　wave　and　S　wave　on　the　three　orthotropic　different　directions　including　parallel　and　vertical　direction　to　the　stratum　of　the　compacted　rock　samples　including　slate,　phyllite,　mylonite　and　metasandstone,　the　two　obvious　anisotropy　effects　of　P　wave　and　S　wave　velocity　are　put　forward.　One　is　the　conformity　of　the　anisotropy　of　P　wave　and　S　wave　velocity　expressed　by　that　the　anisotropic　indexes　of　S　wave　velocity　would　linearly　increase　as　the　P　wave　anisotropic　indexes　increase　in　a　great　degree,　namely　the　anisotropy　of　S　wave　velocity　is　statistically　proportional　to　that　of　P　wave;　the　other　effect　is　the　variation　between　P　wave　and　S　wave　velocity　anisotropy,　which　is　mainly　expressed　by　that　the　anisotropic　index　of　the　P　wave　velocity　is　usually　greater　than　S　wave　in　the　parallel　and　vertical　directions　to　the　stratum　of　the　rock　samples　which　means　that　the　anisotropy　of　S　wave　velocity　is　inferior　to　that　of　P　wave.　Using　numerical　value　test　based　on　the　wave　velocity　function　of　the　transverse　isotropic　elastic　medium,　the　two　effects　are　validated.
