The effect of $q$ -nonextensive electrons, nature, and magnitude of dust charge on magnetized dusty plasma sheath with two ion species has been numerically investigated via fluid model. The initial common speed of ion species at the sheath entrance has been extended, which increases from subsonic to supersonic with the decrease in nonextensive parameter $q$ and ion-neutral drag force as well. The presence of super extensive primary electrons ( $q < 1$ ) has significantly affected the sheath parameters characterizing the dusty plasma sheath: dust charging, potential profile, ion and electron densities profile, ion velocity profile, and dust dynamics. It is found that the negatively charged dust grains accelerate in the region of weak electric field, whereas the fluctuation decreases in the region of strong electric field. A significant change has been observed in dust dynamics with the presence of two different natures of dust charges and its magnitudes. The velocity fluctuations of negatively and positively charged grains are in opposite phase. Furthermore, the comparative study of dust velocity in the presence and absence of dust-neutral collisions has been presented.

两种离子和两种离子的磁化多尘等离子体鞘的特性。 q-非张力电子

的效果 $ q $ -通过流体模型数值研究了具有两种离子种类的磁化尘埃等离子体鞘上的不扩散电子，性质和尘埃电荷的大小。鞘层入口处离子种类的初始共同速度已得到扩展，随着非扩展参数的减小，离子速度从亚音速增加到超音速 $ q $ 以及离子中性阻力。超大范围一次电子的存在（ $ q <1 $ ）已严重影响表征尘土等离子体鞘的鞘参数：尘埃带电，电势分布，离子和电子密度分布，离子速度分布以及尘埃动力学。发现带负电的尘埃颗粒在弱电场区域中加速，而波动在强电场区域中减小。在粉尘动力学中观察到了显着变化，粉尘电荷具有两种不同的性质及其大小。带负电和带正电的晶粒的速度波动是相反的。此外，已经提出了在存在和不存在中性尘埃碰撞的情况下对尘埃速度的比较研究。
