Abstract :
Vertical displacement function of internal waves was transformed from internal wave basic control function, by using small amplitude wave motion hypothesis and the usual Boussinesq approximation. And then eigenfunction was transformed vertical displacement function by using the “rigid lid” approximation. A numerical method was given to gain a series of eigenfunctions of vertical displacement function, using a simple finite-difference technique.
