| 摘 要： | 在静压0~1 GPa（10 kbar）范围内，80~300 K温区，用测量电阻的方法，研究了Bi-Pb-Sr-Ca-Cu-O（起始转变温度Tcon=110 K，终止转变温度Tcfi=106 K）的起导电性。观察到超导临界温度Tc随压力以dTc/dp=2K/GPa的速率增高，而在不同压力下的斜率d logR/dp却保持不变。

| Abstract: | Measurements have been made on the electrical resistance of single phase Bi-Pb-Sr-Ca-Cu-O samples with superconducting onset temperature Tcon= 110K and final temperature 7cff = 106K, under hydrostatic pressures up to 1GPa and temperatures from 80 to 300K. An increase in Tc with pressure, at a rate of dTc/dp=2K/GPa,and a constant slope of (1/R(300K)) (dR/dT) under different pressures, were observed. A possible explanation for the pressure behavior is presented. |
