考虑了电子或激发态在随机占据的点阵上的输运问题。在任何构型中，控制输运的方程被假定为主方程。用投影算符技术推导出控制所有构型上平均输运的精确方程，它可以写成广义主方程或连续时间随机游走方程(CTRW)，从而证明了CTRW对这些问题的正确性。
The transport of electrons or excitations on a lattice randomly occupied by guests is considered. The equation governing the transport in any configuration is assumed to be the master equation. A projection operator technique is used to derive the exact equation governing the transport averaged over all configurations, which can be written as either a generalized master equation or the continuous-time random-walk equations (CTRW), establishing the correctness of the CTRW for these problems.
