摘 要：<正> On microscopic and microstructural lev-els,the relations between high Tc superconduc-tivity and percolation have been discussed.On themicroscopic level,the critical oxygen concentra-tion in YBa2Cu307 with Tc around 90 K hasbeen obtained in terms of percolation.On themicrostruclural level,the percolation considera-tions have provided,usefully theoretical basisfor materials design of metal/high-Tc super-conducting phase（nonmetal）composites.
