The Feynman model is a famous theoretical model establishing the Josephson equations. Feynman et al. based on the Schrodinger equations describing the two states system of superconductor junction, have derived the differential equations of the amplitudes and phases of the two wave functions versus time, and solved them with a slightly rough method, and established the Josephson equation. It is worth considering carefully that mathematical treatment in Feynman model was not exact. In this paper we have solved the differential equations in Feynman model exactly, the results we have gotten show that A. C. Josephson equations can be established only under certain conditions..
