相量模型在高职交流电路教学中的运用

The utilization of measures model in alternating-current circuit teaching in higher professional colleges

在正弦交流电路中,各物理量之间不仅有数量大小的关系,而且还有方向(相位)的关系,在教学中高职院校学生常常感到很困难并经常弄错。本文利用相量模型电路统领正弦交流电路的教学,使学生能运用直流电路的知识和分析方法及思维模式,来分析计算交流电路。通过教学班级对比,教学效果较好。

In the sine alternating-current circuit, various physical measurements not only have the quantity and size relations, but also have the relation in direction （phase）. In the education of the higher professional colleges ,students frequently feel very difficulty and easily make the mistake. The article uses the measures model circuit to command the education of sine alternating-current circuit and enable the students can utilize the knowledge of direct current circuit ,the analyzing way and the thinking mode to calculate the alternating-current circuit. Through the compare of teaching classes, the teaching effect is much better.
