摘　　要：通过对YBCO高温氧化物超导体长期的实验现测，发现空气中的水份和CO2是逐渐侵独到超导体内部的．本文对这一过程进行了分析和讨论，并指出采取适当的保存方法，可使高温氧化物超导体长期保持起导特性．A long run experiment and test in YBCO high-oxide superconductors,we found that YBCO high-Tc oxide super-couductors are corroded gradually by H2O and CO2 in air. We analyze and discuss careful the corrodible process in this paper and point that if adopt currict preservative measure,high-Tc oxide superconductors will remain the ability of superconductor for a long time.
