摘要
该测量方法有效地解决了用热电偶直接带动电表时电表表针偏移很小、造成读数困难，且读数误差较大的问题。对加放大器前后的电路特性做了分析和比较，并对加放大器前后的实验结果进行了分析，得出了增加放大器后的实验结果较未加放大器的实验结果误差较小的结论。
It resolved the problems of driving electric meter directly by thermocouple, the small shift of meter finger, the difficult in reading and large instrumental error, and obtained the result of small experimental error when used the amplifier than unused it by means of anglicizing the properties of electricity.
