摘要：

A heuristic scaling procedure is introduced to describe percolation in bounded systems. For an infinite three-dimensional slab of thickness h, the critical concentration pc is calculated by the Migdal-Kadanoff transformation. In a bulk system of dimension d>1 the concentration p(1>p>pc) increases under scaling, but for d=1 and p<1 it decreases. This difference in scaling behaviour underlies the distinctive cross-over effects in wire geometries.
