The　description　of　the　wave　propagation　in　the　multilayer　adhesive　structure　under　different　forms　of　interfaces　is　very　complex.　For　this　issue,　the　reflection　and　transmission　coefficient　expressions　of　longitudinal　and　transverse　waves　with　the　dimensionless　parameter　of　omega　tau　in　the　trilaminar　plate-like　adhesive　structure　are　derived　when　the　adhesive　layer　is　assumed　to　be　viscoelastic　material　with　a　relaxed　time　of　tau.　Aluminum-epoxy　resin-polystyrene　adhesive　structure　is　taken　as　an　example　to　analyze　the　impact　of　changes　in　the　angle　of　incidence　on　acoustic　wave　reflection　and　transmission　characteristics.　Numerical　results　show　that　regardless　of　the　value　of　omega　tau,　interface　form　can　not　be　identified　in　the　case　of　normal　incidence　or　grazing　incidence　of　longitudinal　wave.　In　a　particular　products　of　frequency-thickness,　if　the　angle　of　incidence　is　appropriate,　the　methods　of　reflection　and　transmission　coefficients　of　longitudinal　wave　or　transverse　wave　reflection　coefficient　can　be　adopted　to　detect　the　perfect,　sliding　and　weak　bonding　interfaces.　The　results　provide　a　theoretical　basis　for　the　experiment　of　the　adhesive　structure　by　means　of　ultrasonic　testing.
