摘　　要：基于Feynman模型得到的Josephson方程,在求解过程中采取了ρ1=ρ2的假设,但这个假设在数学处理上并不严格。为了得到严格的结果,未进行上述假设,通过解微分方程得到了严格的Josephson方程,结果显示在一定条件下才能得到通常所说的Josephson方程。Josephson equation obtains which based on the Feymnan medel, the supposition P1 =P2 has been adopted in the solution process, but this supposition is not certainly strict in mathematics processing. In order to obtain the strict result, we have not carried on the above supposition and obtained the strict Josephson equation through the solution differential equation. The results show that the Josephson equation can be obtained under the certain condition.
