电效应。两种不同的金属焊接在一起可以将热能转化成电能。在炼油厂，根据这一原则，通过使用热电偶来测量温度。
Electrical effect. Two different metals welded together can transform heat energy into electrical energy. This principle is used in the refinery to measure temperature by use of thermocouples.
本文首先阐明了金属切削中热电效应的基本原理。
This paper deals first with the basic principles of the thermo-electric effect in metal cutting.
