摘要：

If a (d minus 1)-dimensional surface of a d-dimensional semi-infinite medium has a concentration p//S different from the bulk concentration p//B one may imagine that percolation is possible even if both p//B and p//S are below the d- and (d minus 1)-dimensional threshold, respectively. Simple arguments, partly confirmed by Monte Carlo experiment, why this effect occurs for d equals 3 but for d equals 2 are given, discussing also the case of a defect line immersed in a three-dimensional medium.
