摘要
本文给出一套测量固体常用低温热参量的计算机控制多功能测试系统,可测量样品的电阻随温度的变化曲线R(T)、0~1.8×103MPa压力范围内电阻的温度特性R(T,P)、比热曲线C(T)及其AC磁化率,温区从液氮温度至室温.该系统集固体基本低温物性测量为一体,精度高,测量迅速、方便,为低温领域的物性分析(特别是高温氧化物超导体的研究)带来了极大的便利.
his paper shows a multifunction system for measuring thermophysical properties of solid-state material in low temperature, which is controlled by IBM PC automatically. It can supply, one by one or four in one times, curves of resistance in low and high pressure, ac susceptibility(including real and imaginary components) and specific heat vs. temperature from 77 K to room temperature.The system is more convenient and can be finished more quickly than separated apparatus. It is very important for studying material properties in low temperature and very useful, especially, for the researches of high-Tc superconductivity.
