A qualitative pattern of the formation and further development of nonlinear stationary structures that describe the final stage of thermal and electromagnetic perturbations in a superconductor is investigated. The wave propagation velocity and the wave front width in a superconductor are estimated.4 pages, LaTex file, 2 figures, EPS file (Physics of Solid State, 43, 3, 413 (2001))Superconductivitytext
