The rotation ellipsoid model was put forward according to the physical development and space profile of plasma,which lay a theory foundation for plasma three dimension model.

In this paper, based on the derived average scattering and alleviating cross sections of the small rotating spheroid raindrop groups having different rotating orientations when their axial orientations are in normal distribution.

The optical center of the rotational ellipsoid and it s thick lens;

The electrostatic energy and potential produced by a unifomlly charged prolateellipsoid of revolution is calculated by means of Legendre functions.
