摘要：

The dynamical exponents of the coordinate and of the mean square displacement are explicitly calculated in the case of a directed random walk on a one-dimensional random lattice. Moreover, it is shown that, in the dynamical phase where the coordinate increases slower than t, the latter is not a self-averaging quantity. © 1990 Plenum Publishing Corporation.
