研究了强耦合可变电荷尘埃等离子体中静电短波长离子波的调制不稳定性。得到了尘埃慢运动调制离子波的演化方程。这种不稳定性行为与弱耦合尘埃颗粒的等离子体的不稳定性行为有很大的不同，并且强烈地依赖于库仑耦合参数以及尘埃电荷弛豫速率。
Modulational instability of electrostatic short-wavelength ion waves in plasmas containing strongly coupled dusts with variable charge is considered. The evolution equations for the ion waves modulated by slow dust motion are obtained. The instability behavior differs considerably from that of plasmas with weakly coupled dust grains and depends strongly on the Coulomb coupling parameter as well as the dust-charge relaxation rate.
