摘　　要：提出一种用酸溶解块材YBa_2Cu_3O_x并测定其中氧及三价铜含量的方法。估计了方法的系统误差(小于3%)。对该法与热重分析法的结果作了比较。A simlpe and convenient method of determining the content of oxygen andCu(III)in YBa_2Cu_3O_x bulk is proposed. It is based on measuring the volume ofoxygen liberated from the sample dissolved with acid. The result is compared withthat obtained from thermogravimetric analysis method and the systematic erroris estimated. The error is less than 3%.
