本文用高温微热量热计HT1000和差示扫描量热计DSC-111,采用热化学的方法测定了钇钡铜氧高温超导体系中二元复合氧化物Y_2Cu_2O_5的标准生成焓和热容,结果为: △~H_(f,298)~o=-2198.67kJ/mol Cp=149.82+0.11302T（J/mol.K）（298—973K）
In this paper, the standard formation enthalpy and heat capacity of binary composite oxide Y2Cu2O5 in yttrium barium copper-oxygen high-temperature superconducting system were determined by thermochemical method with high-temperature micro-calorimeter HT1000 and differential scanning calorimeter DSC-111. As follows: Δ ~ H_ (f, 298) ~ o = -2198.67kJ / mol Cp = 149.82 + 0.11302T (J / mol.K) (298-973K)
