摘要：

The specific heat anomaly of a polycrystalline sample of BPSCCO (2223 phase) was found to have a peak height-delta-C(T(c))/T(c) almost-equal-to 24 mJ/mole K2 at T(c) almost-equal-to 107 K. The anomaly provides evidence for a fluctuation contribution above T(c), whereas below T(c) it is not possible to separate fluctuation and strong-coupling effects. A second, considerably smaller, anomaly appears at T almost-equal-to 101 K when the sample is cooled rapidly from 140 K to 78 K.
