| Abstract: | According to the mechanics theories and the classical electromagnetism,the motion of 2-dyon systems was studied.Some integrals of motion,including the energy integral,the total angular momentum integral and the Runge-Lenz-like integral,were derived from the differential equations of motion for the system,then the SO (4) symmetry of the system was exposed.With the inverse problem method of variational calculus,the Lagrangian function and the Hamiltonian function for the 2-dyon system were constructed.The classical motion of the system is completely integrable,the equations of the orbit and the relation between radial distance r and time t are solvable. |
