我们知道，摩擦可以起电。摩擦后的正负电荷是被束缚在带电体上的，它不能像电线中的电荷那样定向移动，所以，人们称之为静电荷，简称静电。静电的危害很多，它的第一种危害来源于带电体的互相作用。在飞机机体与空气、水气、灰尘等微粒摩擦时会使飞机带电，如果不采取措施， We know that friction can power. Friction of the positive and negative charges are bound to the charged body, it can not be the direction of electric charge in the wire as moving, so people call it electrostatic charge, referred to as static electricity. Electrostatic hazards are many, its first harm comes from the charged body interaction. In the aircraft body and air, water vapor, dust and other particles will make the aircraft electrified friction, if you do not take measures,
