摘要：

Wave characteristics of solitons with damped structures in a four-component plasma fluid having positive and negative ions, nonthermal distributed positrons and electrons have been studied. The damped Kadomtsev-Petviashvili (DKP) equation has been obtained in a small amplitude limit. The nonlinear criticality of DKP is examined for related Earth's ionosphere plasma parameters. The effects of the positron density ratio, the ionic mass ratio, the electron density ratio, the index of non-thermality and frequency parameters of collisions on the formation of both damped structures of compressive and rarefactive types are studied. It is a value mention that the results performed in this work may be used in the plasma of (D-F) Earth's ionosphere regions.
