Query: Uemura Plot as a Certificate of Two-dimensional Character of
  Superconducting Transition for Quasi-two-dimensional HTS   With using general properties of superconducting state for 2D systems the
universal temperature dependence of the penetration length is found out for
quasi-2D HTS, that leads to Uemura plot and evidences about 2D character of
superconducting transition. It is shown that from the measurements of c-axis
resistivity and of the penetration length the value of the interval of 3D
superconducting fluctuations can be determined.
