提出了一种测定热电器件珀尔帖系数的新方法。通过测量两种不同材料X和y交界处的温度分布来评估珀尔帖系数。利用能量平衡将珀尔帖系数与热电模块（TEM）金属块的冷热温度联系起来，从而能够评估该系数。还需要关于颗粒导热性的数据。本文使用的实验装置是由N = 71对碲化铋组成的透射电镜，适当掺杂以提供单独的N和p元素。利用制造商给出的瞬变电磁法塞贝克系数的标称值，证实了Onsager互反关系。
A new method for determining the Peltier coefficient of thermoelectric devices has been developed. The Peltier coefficient has been evaluated by measuring the temperature distribution along the junction of two dissimilar materials X and Y. The energy balance has been used to link the Peltier coefficient with the hot and cold temperatures of the metallic blocks of a thermoelectric module (TEM), thus enabling the evaluation of this coefficient. Data on the thermal conductance of the pellets are also needed. The experimental device used in this paper is a TEM composed of N = 71 couples of bismuth telluride, suitably doped to provide individual n and p elements. Using nominal values given by the manufacturer for the Seebeck coefficient of the TEM, the Onsager reciprocal relation has been confirmed.
