In very violent events, electrons from the atoms in one material can get stripped off and passed to another material, causing both materials to become charged, this one positively, because it lost electrons, and this one negatively, because it gained electrons.
在非常劇烈的事件中,一種材料中原子的電子會被剝離出來,傳遞到另一種材料中,導致兩種材料都帶電,這種材料帶正電,因為它失去了電子,而這種材料帶負電,因為它獲得了電子。
