Query: Comparison of the fluctuation influence on the resistive properties of
  the mixed state of BiSrCaCuO and of thin films of conventional superconductor   The resistive properties of layered HTSC BiSrCaCuO in the mixed state are
compared with those of thin films of conventional superconductors with weak
disorders (amorphous Nb_{1-x}0_{x} films) and with strong disorders
(Nb_{1-x}O_{x} films with small grain structure). The excess conductivity is
considered as a function of superconducting electron density and phase
coherence length. It is shown that the transition to the Abrikosov state
differs from the ideal case both in BiSrCaCuO and Nb_{1-x}O_{x} films, i.e. the
appearance of long-range phase coherence is continuous transition in both
cases. The quantitative difference between thin films with weak and strong
disorders is greater than the one between layered HTSC and conventional
superconductors, showing that the dimensionality of the system, rather than the
critical temperature, is the key factor ruling fluctuation effects
