Effects of the nonthermal distribution of electrons as well as the polarity of the net dust-charge number density on nonplanar (viz. cylindrical and spherical) dust-ion-acoustic solitary waves (DIASWs) are investigated by employing the reductive perturbation method. It is found that the basic features of the DIASWs are significantly modified by the effects of nonthermal electron distribution, polarity of net dust-charge number density, and nonplanar geometry. The implications of our results in some space and laboratory dusty plasma environments are briefly discussed.
通过采用约化摄动法，研究了电子的非热分布以及净尘埃电荷数密度的极性对非平面（即圆柱和球形）尘埃离子声孤立波（DIASWs）的影响。研究发现，非热电子分布、净尘埃电荷数密度的极性以及非平面几何形状的影响显著改变了尘埃离子声孤立波的基本特征。简要讨论了我们的结果在一些空间和实验室尘埃等离子体环境中的意义。
