During our college class, we did many electrical and electronic experiments, but this term we have done two important experiments. The first one is to control electric motor, the other is make a radio. I once mentioned them summer holiday. Now, I will remember the two experiment with pictures. Since my thermoelectric experiment is not a necessary [...]

这学期的电工电子实验有两个是比较重量级一点的，首先就是电动机的控制，另外一个就是自己动手制作收音机的实验，在我的暑假一文稍微提到过这点，以下在来细细的回顾一下这两个实际动手操作的实验。 这两个实验都是电工电子课程安排的必修实验，而温差发电实验研究实验项目则是自己申

We are now doing a research on thermoelectric. Yesterday, zhangpeng stayed at lab for a whole day except having lunch. We have done many experiments on the thermoelectric generator. I’l like to share some picture with you also to encourage myself. Thermoelectric generation based on theory of seececk effect. experiment

一直在做半导体温差发电器温差发电的实验研究,今天张鹏和同学甚至是九点到五点除了中餐都呆在实验室,一直调试设备测试数据,坐都坐累了,一下发几张实验装置的图片来算是犒劳下自己咯. 温差发电基于塞贝克效应，至于塞贝克效应原理可以参考之前的文章：塞贝克效应，利用塞贝克效应制成半导

上学期学习了燃料及燃烧这门课程,期末作业有一个燃料及燃烧计算的程序,要求是把书本上所有在燃烧与燃烧设备中涉及到的计算用C语言程序实现,省去人工计算的麻烦. 于是张鹏便制作了这个燃料及燃烧的C语言计算程序. c语言, 作品, 燃烧

有时候,尤其是在冬天，我们会觉得流动的水温度比在容器中的水温更高。或许会以这样的形式为你所感知：当你准备洗头发的水，你把手放到水龙头下试水温，你觉得已经够热了，不过当你把头发泡进盆子里的时候才觉得水真是太冷了。然后你又把手放到盆子里试一下，水温似乎是降低了。 那么以

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: innovation, 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. 创新, 热电偶
