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 you put your hand into the basin, the temperature seems decreased.

Let me have a brief research on this interesting phenomenon. Is the temperature decreased rapidly during its way to basin?www.zhangpeng.info

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.

又是周末了,一个星期过的还真实快.看看这个星期都作了什么?当然所说的要除去听课.

周一张鹏做了个PPT,也就是那个吸附式制冷的课件.然后周五下午去实验室呆了一个下午,基本上也就是研究了一下新进制冷系统的使用,其实主要就是研究那个什么xmt60x系列智能控制仪表的使用,貌似用的是xmt602的仪表,弄到六点,算是弄清楚了.

另外的空闲时间,周二上午和周三下午基本都睡了觉了.

这或许是张鹏少量几篇先有英文再有中文的文章之一，主要是因为是在一个英语教学课上要用到这个PPT，所以就先有英文版的咯。

吸附式系统包括太阳能集热器、冷凝器、储液器、蒸发器和阀门。 » Read more
