单词	random walk
释义	random walk The problem of determining the distance from a starting position made by a walker, who can either move forward (toward +x) or backwards (toward -x) with the choice being made randomly (e.g. by tossing a coin). The progress of the walker is characterized by the net distance D_N travelled in N steps. After N steps the root-mean-square valueD_rms, which is the average distance away from the starting position, is given by D_rms = vN . Physical applications of the random walk include diffusion and the related problem of Brownian motion as well as problems involving the structures of polymers and disordered solids
