Taw qhia ntawm quasi-P yoj
Lub seismic yoj nthuav tawm hauv anisotropic media, thaum lub kaum sab xis ntawm qhov tshwm sim ntawm qhov interface tsis yog xoom lossis 90 °, qhov kev co ntawm P nthwv dej thiab SV yoj yog ua ke, thiab muaj cov peev xwm tawm thiab qhov chaw vector txawv ntawm P nthwv dej. lossis ntshiab SV yoj hauv isotropic media, yog li nws yog hu ua quasi-longitudinal wave thiab quasi-S-wave.
