The motion of the interstellar gas in the gravitational field of a spiral density wave is investigated. By numerical integration of non-linear gas dynamic and thermal processes equations it is shown that the rotation of the galactic disk is a necessary condition for a phase transition and formation of a cloud structure in the gas, flowing in the field of a spiral arm by thermal instability. In a thin, dense gas disk, the combined effect of the gas self-gravitation and thermal processes is found to lead to formation of structural features characterized by rapidly growing density and falling temperature; however, no indication on gravitational fragmentation within these dense, cool regions is found.
