电是个奇妙的东西,它无时不在,无处不有。人的身体有电,人的周围都是电的环境。如果说你用的钢笔、书本带有电,你或许不同意,但你若把钢笔放在头上摩擦几下,它就能吸起小纸片、粉笔灰等,这说明钢笔带电。有许多物体,只要把其中两种放在一起磨擦,它们都将带电。这种由磨擦或碰撞产生电的现象叫做静电现象或放电现象。 Electricity is a fantastic thing, it’s everywhere and everywhere. The human body has electricity, people are surrounded by the electrical environment. If you use a pen, the book with electricity, you may not agree, but if you rub the pen on the head a few times, it can suck a little piece of paper, chalk, etc., indicating that the pen charged. There are many objects, as long as two of them together friction, they will be charged. This phenomenon of electricity generated by friction or collision is called electrostatic phenomenon or discharge phenomenon.
