摘      要：The parametrically-driven,damped nonlinear Schrodinger equation is numerically investigated and the parameter regions for the double-solitons of like polarity are *** simulations of the soliton evolution in the parameter regions are in good agreement with the experimental *** computations also reveal that the“particles number,momentum and energy are no more constants but vary in a periodic fashion in the system.
