抄録

A model equation as above (Boussinesq form) which governs the lattice wave and shallow water waves, has been reduced to a modified form of Hirota equation for intermediate range of wave number (k<1), considering the case when the central wave number k and the spectral width Δk∼ε of the wave packet are both smaller than unity but of comparable magnitude. For the modified Hirota equation, the envelope soliton solution is obtained and the condition for modulational instability is derived. This is found to differ appreciably from the corresponding condition for non-linear Schrödinger equation.
