摘要：

Previous forms of the generalized nonlinear Schrodinger equation are ambiguously related to the corresponding nonlinear dispersion relation. In the present paper we therefore propose a Hamiltonian equation which is determined in a unique way. Soliton solutions of the nonlinear Schrodinger equations are found, and modulational instabilities are investigated.
