某些物质同纺织品相摩擦就会使电子从一方转移到另一方,从而导致双方产生电荷。一方失掉电子就产生了正电荷,另一方留住电子就产生了负电荷。电子的这种转移被称为摩擦生电效应。它的强度各有不同:比如,空气干燥时,其导电性能最差,结果就是物体本身长时间保持着电荷。另外还应考虑到所穿衣服的种类:合成纤维趋向保留电子而产生负电荷;相反,毛、丝或动物皮毛是释放电子的,故而产生正电荷。当我们从汽车里出来时
The friction of certain substances with textiles will transfer electrons from one side to the other, resulting in both parties generating charges. The loss of electrons on one side creates a positive charge, while the other side holds electrons and produces a negative charge. This transfer of electrons is called triboelectric effect. Its strength varies: For example, when air is dry, its electrical conductivity is the worst, and as a result, the object itself maintains its charge for a long time. In addition, the type of clothing worn should also be considered: synthetic fibers tend to retain electrons and produce negative charges; in contrast, wool, silk, or animal skins release electrons, and thus produce positive charges.
