在我们这个由原子组成的世界中,有一个特别的法则,只要有两个以上的原子组合在一起,它的外围电子就一定要配对,如果不配对,它们就要去寻找另一个电子,使自己变成稳定的结构。科学家们把这种有着不成对电子的原子叫做自由基。当一个稳定原子的原有结构被外力打破,而导致这个原子缺少了一个电子时,自由基就产生了。当自由基与其他物质结合的过程中得到一个电 In our atomic world, there is a special rule that as long as there are two or more atoms together, their peripheral electrons must be paired. If they do not pair, they will look for another electron so that I became a stable structure. Scientists call this atom with unpaired electrons a free radical. When a stable atom of the original structure is broken by external forces, resulting in the absence of an electron atom, the free radicals are generated. When the free radicals and other substances in the process of getting an electricity
