| 摘 要： | 本文设计了一种交流法测量室温到1200K的热电势的实验装置。与传统的直流测量方法相比，这一方法有许多优点：方便、适合小样品、能够测量单晶的各向异性，可以连续的测量热电势对温度的依赖关系。为了检验这一新方法的可靠性和准确性，我们测量了纯Pt丝的热电势。

| Abstract: | An experimental set-up for ac-measurement of thermopower between room temperature and 1200K by using modulated laser-heating has been developed. The method shows many advantages compared with the conventional dc-measurements: convenience, applicability to small samples, possibility to measure the anisotropy of single crystals, and capability to continuously trace the temperature dependence of thermopower. The thermopower of a very short piece of pure Pt was measured with the present set-up to test the reliability and accuracy of our new method. |
