Sometime, especially in winter, we find the temperature of flowing water is higher than the water in a container. You may notice the phenomenon like this, when you washing your hair, you think the temperature of flowing water is just perfect. But you then find it too cold after you had wetted your hair. So […]

Thermocouple is a thermograph which uses Seebeck effect to measure the temperature. When two different metal make up a surround, the temperature difference between two combining site will cause electric current . So we use measure this electic current and then canculate the temperature. This is just a simple example of thermocouple:

热电偶是一种基于塞贝克效应的测温仪器.当两种不同的金属组成回路时,若两金属结合点温度不同,回路中将产生电流.据电流大小来测温.以下就是其原理图: 其中1点和2点温度不同便会产生电流,基于此制作出热电偶.
