The information resource navigation system for chemistry education has offered a kind of web platform based on data,which can satisfy the need of the classification of chemistry resources.

In order to solve the problems of consistency and of process navigation in the enterprise view model, a kind of modeling structure based on resource navigation is designed.

Starter/generator aero power system which is composed of induction machine and power electronic converter is significant.

In this paper, the author regarding the EMC testing of some airplane AC power supply system as the example, introduces the EMC test measurement and process of the aircraft power supply products, and analyzing of results and EMI control measures, bring upped the suggestion of solution for these problems.

Monolithic integrated circuit(IC)of the aircraft power supply product can help to design more effective,better-reliability,but electromagnetic interference(EMI)problem of the aircraft power supply product become more complicate than before and the potential damage to other device goes high risk.

In this paper,the author regarding the conducted emission (CE) detecting of some aircraft power supply product s power line as the example,introduces CB test measurement and process of the aircraft power supply product,and analyzed of results and EMI control measures.
