BaPb_(0.75)Bi_(0.25)O_3交流互感的测量(英文)

A.C. INDUCTANCE MEASUREMENT OF BaPb_0.75Bi_0.25O_3

本文主要描述了怎样通对超导粉末材料BaPb_(0.75)Bi_(0.25)O_3交流互感的测量获得它的临界温度（T_c）。将样品放到磁场中,当磁场改变时,其监界温度T_c也随着变化。

This paper shows how to get the critical temperature (TV) of superconducting grains of BaPb0.75Bi0.25O3 by the a. c, inductance nneasurement. Furthermore, the sample was put in magnetic field. While the magnetic field is changing,the critical temperature is being changed.
