主　　题：Scholte waves in the ocean and oceanic crust dispersion equation propagation velocity amplitude,mode of motion 

摘      要：The dispersion equation of the Scholte wave was reviewed using the homogeneous elastic half-space covered by a liquid layer,and the range of the Scholte wave propagation velocity was examined using the dispersion *** displacement expressions of the Scholte waves in liquid and solid were ***,the mode of motion of Scholte waves in liquid and solid and their variation with depth was *** following results were obtained:The dispersion equation shows that the propagation velocity of the fundamental Scholte wave was greater than the P-wave in liquid and less than that of the Scholte wave in homogeneous elastic *** contrast,the velocity of higher-order Scholte waves was greater than that of P waves in liquid and S-waves in *** the fundamental Scholte wave has no cutoff *** Scholte wave at the liquid surface moved only vertically,while the particles inside the liquid medium moved *** amplitude variation with depth in the solid medium caused the particle motion to change from a retrograde ellipse to a prograde *** above results imply the study of Scholte waves in the ocean and oceanic crust and help estimate ocean depths.
