Sergeeva %J Physics %D 2001 %I arXiv %X 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. %U http://arxiv.org/abs/cond-mat/0102293v1
