加强数学思想在交变电流教学中的渗透

Strengthening the Infiltration of Mathematical Thinking in the Physics Teaching of Alternating Current

在交变电流的知识体系中 ,一些物理量的制约关系 ,与数学中一些数量制约有着相似之处。正弦式交流电的图象与正弦曲线完全吻合 ,它们满足相同的规律。研究数学的思维方法 ,在交变电流中体现出来 ,在教学中渗透这种思想 ,可开阔学生思维 。

In the knowledge system of alternating current,the restrictive relationships of some physics quantities are similar with those of mathematical numbers.The picture of sine-like alternating current tallies with sine curve and they content the same physics law.The mathematical way of thinking,which embodied in the physics alternating current teaching,can widen the students's views of thinking and enhance the abilities of solving problems.
