摘要：
The electrical resistance R in a superconducting Ba1-xKxBiO3 single crystal is studied as a function of the temperature T and the current I. The measurements performed without applied magnetic field indicate that the flux lines are generated by the self-field and that several transitions contribute independently to the R(T) and R(I) characteristics. A phenomenological expression of the R(T, I) dependence is proposed.
