摘要

Wave properties of solitons in an unmagnetized four-component dusty plasma system contains isothermal distributed electrons,mobile ions,and negative-positive dusty grains have been examined.To study DIA wave properties,a reductive perturbation (RP) analysis is used.By a reductive perturbation (RP) analysis under convenient coordinate transformation,the three dimension Kadomtsev-Petviashvili equation in cylindricai coordinates is obtained.The effects of dust grain charge on soliton pulse structures are studied.More specifically,solitary profile depending on the axial,radial,and polar angle coordinates with time is discussed.This investigation may be viable in plasmas of the Earth's mesosphere.
