摘 要：正In this paper,using nonlinear Schrodinger equation and Continuum Approximation Method,the basic equations defining the motion of an electron in polymer molecular chain excited by microwave radiation have been *** solutions of the equations and the energy of the polymer system have been *** result shows that the interaction of an electron with chain deformation stabilizes its motion （quasi-superconducting state）.For polyisobutene radiated by microwave in constant intensity,calculation is in agreement with experimental measurement for nonlinear breakdown *** would be important to seek the cause of a decrease in the breakdown voltage for polymer materials under radiation conditions.
