摘　　要：采用相干态平均方法求出压缩哈密顿系统的演化算符，并用正规乘积内的积分方法求算它的Ｆｅｙｎｍａｎ转移矩阵元。当系统外源为实常数时，充分利用压缩么正变换的特性简便地计算了系统在坐标本征态和压缩态之间的转移矩阵元。The evolution operator for a sgeeged Hamiltoniam system was got out by the method of expectation value between coherent statesand it's Feynman transfer matrix element was calculated by the integrations within normal multiplcation when the extra source for a system was a real constant ,making good use of the property of the sqeezeunitary transform,the transfer matrix element between the corrdinate eigenstate and the squeezed state was easy calculated.
