物理和化学中曾先后学到中和与中性,但在不同学科中其意义各不相同.物理中是对电荷而言,而化学中是对酸碱而言.物理中的中和与中性也是不同的概念,中和是一种现象、中性是一种性质.中和指的是等量异种电荷放在一起完全抵消的现象,如雷电的发生就自然界中的一种中和现象,中和后物体对外不显电性.值得注意的是电荷中和时,正、负电荷相互抵消,而不是消失、原正、负电荷的性质和总量都没有变.中性指的是原子核所
Physics and chemistry have learned neutrality and neutrality one after another, but in different disciplines their significance is different. In physics it is the charge, and in chemistry it is the acid and alkali. In physics the neutralization and the middle Sex is also a different concept. Neutralization is a phenomenon. Neutrality is a property. Neutralization refers to a phenomenon in which equal amounts of different kinds of charges are put together to completely cancel each other. For example, the occurrence of lightning is a phenomenon in the nature. After neutralization, the object is not electrically active. It is noteworthy that when the charge is neutralized, the positive and negative charges cancel each other out instead of disappearing. The nature and total amount of the original positive and negative charges have not changed. Neutral refers to Nuclear Institute
