Considering a model with continuous change of the conductance
S

, we assume
that intensity of the
S
-effect depends on relation between generation of excess cur-
rent in the upper layer and its leakage into the underlying intermediate layer. To
gain a better insight into this mechanism, we examine a two-dimensional model
suggested by Kuznetsov (2005). Letting
