摘要：
The Wigner function, a kind of wavelet transform is studied for one- and two-soliton solutions to the nonlinear Schrodinger equation. The exact expression of the Wigner transform for the one-soliton solution is obtained. The features of soliton-soliton interaction of different two-soliton states, the states of coherence analogous to that of two-localized wave packets in quantum mechanics, are displayed. Suitability of this transform for analyzing ''soliton'' in open systems is also discussed.
