人类对物质的认识总是由浅入深的。开始,我们只是知道可以触摸的固态和液态,后来,通过对动物的呼吸、台风、木材的燃烧等现象的探究,让我们逐步认识到了气体的存在。那么,物质有没有第四种状态呢?回答是肯定的,那就是等离子体。 Human understanding of matter always goes deeper. At the beginning, we only knew the solid and liquid that we could touch. Later, through the exploration of animal breathing, typhoons, wood burning, and other phenomena, we gradually realized the existence of gas. So, is there a fourth state of matter? The answer is yes, that is the plasma.
