  It is shown that transition from the mixed state without the phase coherence
to the mixed state with the long-range phase coherence (i.e. to the Abrikosov
state) of superconductors without disorder must be first order phase
transition. The phase coherence appearance in thin superconducting film with
strong disorder is considered. The observed smooth transition is explained by
increasing of the effective fluctuation dimensionality (from zero to one) in
superconductors with strong disorder. Mendelssohn model is used for the
explanation of the resistive properties of film with strong disorder.
