Abstract: Last years many interesting effects related to incoherent MAR have beenexperimentally found, but only few of them were theoretically explained. It wasshown, for example, that if the voltage at the edges of a linear array is $V$then subgarmonic structures in the current -voltage characteristics appear notonly at usual for nonstationary Josephson effect positions, $V n=2\Delta-n$,where $n$ is integer, but also at voltages other than $V n$. A step towardsdescription of electron transport in a dirty array of SNS junctions is done inthis letter. It is shown that subgarmonic structures may indeed appear at``unusual- voltages.
