通过只处理坐标表示中自由粒子的薛定谔方程,利用偏微分方程组的自相似解方法,导出了时间t的ψ(r,t)在初始时刻t0的ψ(r,t0)的表达式。由于薛定谔方程的复杂性,使用格林函数是必要的。同样的技术也可以应用于波包在耗散介质中传播的情况。
By dealing with the Schrodinger equation for a free particle in the coordinate representation alone, the expression for ψ (r,t) at time t is derived in terms of ψ (r,t0) at an initial instant t0 with the use of the ’’method of self‐similar solution of partial differential equations.’’ The use of Green’s function is necessary due to the complex nature of the Schrodinger equation. The same technique can also be applied to the case of spreading of wave packets in a dissipative medium.
