This paper introduces the CAN field bus and its characteristics，presentes a kind of single Temperature Measurement node based on CAN bus，and offeres the realization of hardware and design of the measurement node．The results show that the CAN bus can improve the time，distance and dependability of the signal transmission，and the measurement precision is improved remarkably．

IIS is the ASP server, while Tomcat can be used as the Java Web server. In the aspect of the processing speed of static resources and the function of Web server management, Tomcat is not as good as IIS server. Therefore, Tomcat is often integrated with other HTTP server in practice. This paper discusses the integration of Tomcat and IIS server, extends the function of IIS server, supporting Java Web applications.

With the further renovation of electricity system in our country，the stability and reliability of electricity supply and consumption have been effectively improved． But the meter reading and data collection still lag behind the times．With the continuous maturity of communication technology of low-voltage power line carrier，we witness the hope of remote meter reading through utilizing this technology．Based on current PLC technology and the successful cases domestically and overseas，this paper conducts the valuable exploration and researches on hardware composition，construction and the design of software and protocol．

With the rapid development of network technology，online fitting is becoming a new consumption of clothing for people．Online fitting is almost based on 2D until now，and is lack of all-round display．There are some 3D fitting systems based on modeling and rending，but they are too complex to produce，high cost and poor color reproduction，so they are not effective．Therefore，this paper puts forward 3D online Fitting System based on Flash．It uses photographs for 3D display of clothes．This system has a high practical value．
