The Landau damping of the dust ion-acoustic wave (DIAW) in a dusty plasma with non-extensive distributed components is analysed relying on the kinetic approach. The electron, ion, and dust particles are effectively modelled by the non-extensive distribution function of the Tsallis statistics. For a collisionless plasma with different values of plasma components indices, the general dispersion relation is achieved, and the non-extensivity effects on the frequency, as well as the Landau damping of the DIAW, are studied. We show that for , the preliminary results of the Maxwellian plasma are obtained. The decrease of wave damping is achieved by increasing the coefficient q index and the ion-to-electron density ratio. The damping rate also increases with an increasing ion-to-electron temperature ratio.

非广泛分布的尘埃等离子体中DIA波传播的动力学方法

依靠动力学方法分析了具有非广泛分布分量的尘埃等离子体中尘埃离子声波 (DIAW) 的朗道阻尼。电子、离子和尘埃粒子通过 Tsallis 统计的非广泛分布函数进行有效建模。对于具有不同等离子体成分指数值的无碰撞等离子体，得到了一般的色散关系，并研究了非延展性对频率的影响，以及DIAW的Landau阻尼。我们表明，对于，获得了麦克斯韦等离子体的初步结果。波阻尼的减小是通过增加系数 q 指数和离子电子密度比来实现的。阻尼率也随着离子与电子温度比的增加而增加。
