介绍一种可用于测定极化晶体热电系数的方法。此法是由将材料当作恒流发生器的等效电路所推导出的简单关系为根据的。当采取一些特殊的预防措施,适当设计和调节试样的加热器来大大降低不均匀的加热,测得的系数就不会受到由第三热电效应所产生的影响。 A method that can be used to determine the thermoelectric coefficient of polarized crystals is introduced. This method is based on the simple relationship derived from the material’s equivalent circuit as a constant current generator. When special precautions are taken to properly design and adjust the sample heater to reduce uneven heating considerably, the measured coefficients are not affected by the third thermoelectric effect.
