| Abstract: | The nonlinear three_dimensional Debye screening in plasmas is investigated. A new kind of analytical equation, which is in agreement with the three_dimensional Poisson equation for the nonlinear Debye potential, is obtained. It is shown that the symmetry distribution of the Debye screening in plasmas can be described by the equation. |
