1) As an engineering professional and basic course, electrotechnology course construction must introduce in new mind and mode of network information.

2) Starting the three - phase asynchronous motor is important in the teaching and experiment Electrotechnology.

3) The frequency and phase difference are measured by means of model 8031 uniprocesser. The exact values of L and C can be calculated automatically through the rulers in principles of electrotechnology .

4) Based on the fast development of science and technology, the application of computer software is more and more extensive, and so the electrotechnology teaching has been improved.

5) This article attempts to conclude and discuss the management and construction of the Electrotechnology and Electronics Experimental Centre of Zhejiang University under new situation.

6) The program can be widely applied to the analysis and integration in the areas of engineering, such as electronics, electrotechnology, civil engineering and architectural engineering, etc.
