The thesis makes a quantitive study of the potential and eletric distribution inside and outside the even spherical medium put on even intensity electric field, discusses when ε_1/ε_2→0 andε_1/ε_2→∞, the distribution regularity of polarization charge on the surface of spherical medium and the distribution of potential and electric field.
In this article, I study primarily the crushing mechanism of Annular Gap Affritor and the movement law of the medium-ball in it from two aspects: theory and practice, the main innovations of this article are listed below:(1) Given out the key formula for Annular Gap Affritor' s crushing speed.
In addition, this article also analyzed the crushing model of Annular Gap Affritor, the law of the crushing-force in Annular Gap Affritor changes with the rotator' s rotating speed and the influence of flux and pressure to the force received by medium-ball.
The mathematical model of the magnetic scalar potential of a system for a magnetic monopole and magnetic medium sphere are introduced We can solve magnetization, magnetizing field and force of this system by using the model.
A simple method of calculation electrostatic potential of a medium sphere in external uniform electrostatic field was given in this paper. In the calculation we only used integration instead of solving Laplace equation.
