求翻译：For high head machines the radial velocity vibrations at the turbine bearing are strongly linked to pressure pulsations below the head cover and are not related to radial forces from the turbine runner. These vibrations are at high frequencies and high velocities and are often linked to low displacements and thus low s是什么意思？ 待解决
