In this thesis, an unmagnetized, collisionless dusty plasma which consisted of extremely massive, highly negatively charged dust particles, ions and electrons are studied. Considering the effects of hot dust fluid with non-thermal ions and variable dust charge, we study the self-consisted system parameters on the structures of the dust-acoustic solitary waves by reductive perturbation methods.

本论文研究无磁化、无碰撞的、由大质量且带负电量的尘埃颗粒、电子和离子组成的尘埃等离子体,考虑尘埃流体的温度、非热离子和尘埃颗粒电荷绝热变化的因素,使用约化摄动方法研究这个自洽的系统的参数对尘埃声孤波结构的影响。
