摩擦生电,作为一种习以为常的物理现象,曾经激发了无数人的探秘热情。然而,人们更多的还是关心摩擦的负面效应,因为干燥环境下由于摩擦而产生的静电常常让人头疼不已。既然生活中摩擦无处不在,如何让这个令人厌烦的问题变成人见人爱的“正能量”?今天,我们就给同学们说一则利用摩擦进行发电的传奇故事。 Trichoelectricity, as a habitual physical phenomenon, has inspired countless people’s enthusiasm for exploration. However, people are still more concerned with the negative effects of friction, because static electricity due to friction in a dry environment is often irritating. Since the friction in life is everywhere, how can we turn this boring problem into a positive “positive energy”? Today, we give our students a legend to use friction to generate electricity.
