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.

最近在筹划着把Zblog转移到 wordpress 系统，主要原因是空间的问题，以后可能就只用Dreamhost的PHP空间了，所以提前把博客也转移到Wordpress平台，免得到时候比较忙弄得手忙脚乱。说无缝转移主要是URL结构保持不变和Tag不变 网上搜索z-blog平滑转移到 WordPress平台的方法有很多，应该来说基本都是那么几个版本了，当然我没有具体去了解很多，就我看到的都是比较古老的了，不过Neeke提供了一个最新版本的转移到wordpress的方法，在文中也提及了一些SQL语句
Time flys . It’s weekend now . Let’s review my life in this week . Our group finished an PPT on Monday , which you see at Brief introduction about desiccant system . Stay at lab for a whole afternoon on Friday , just learn how to use a new cooling system . While most […]
