摘要：

A measurement algorithm and the required instrumentation for computer automation of temperature dependent thermopower measurements over the range of 4.2 to 350 K are described. The performance of the measurement system is demonstrated by examining typical results obtained on bulk and thin film samples of the thallium-based ceramic superconductor. © 1990 IEEE
