1关于静电静电作为一种自然现象而时刻存在着。当2种不同物质组成的固体相互接触后,一个固体上的自由电子会转移到另个固体上,其结果使2个固体分别带上等量异种电荷。当2个固体再次分开时,如果固体表面的电荷来不及中和,就会使固体带上静电。当静电通过人或其他接地导体向大地 About static Electrostatic static as a natural phenomenon and there. When the two different solid substances come into contact with each other, one solid free electron will be transferred to another solid. As a result, the two solids will carry the same amount of different charges. When the two solids are separated again, the solid can be electrostatically charged if it is too late for the charge on the solid surface. When static electricity through the human or other grounding conductor to the earth
