摘要：

Using the Monte-Carlo technique we studied the isotropic layered xy-model. We concentrate on the fall of the transition temperature T(c), the behavior of the specific heat and the vortex density with reduced thickness. Our approximate Ginzburg-Landau treatment suggests that the drop of T(c) resulting from the dimensional crossover is a combination of fluctuation and boundary effects.
