Based on the nonlinear Schrdinger equation,we have simulated the multiple filamentation of locally modulated laser beams,and found that for B integral smaller than some values the local modulations grow to form filaments mainly by drawing energy from that part of background beam;the evolution of two parts of local modulation are basically independent if they are sufficiently far away from each other.
