自然界的物质一般都呈三种状态,即固体、液体和气体。随着人们对大自然的认识越来越深入,人们找到了物质的第四种状态,即等离子体。等离子体是一种气体,但与一般气体不同,它是一种带电的微粒团,就是把能量增加到气体内,使其分解为电子和正离子微粒,从而成为等离子体。要使气体变成等离子体需要很大的能量。所以很难见到。但在太空中,包括太阳在内,百分之九十以上的物质都是以等离子体状态存在。 The material of nature are generally three states, namely solid, liquid and gas. With the deepening of people’s understanding of nature, people found the fourth state of matter, namely plasma. Plasma is a gas, but unlike normal gases, it is a charged micelle that adds energy into the gas and breaks it down into electrons and positive ions that become plasma. It takes a lot of energy to make the gas plasma. So hard to see. But in space, including the sun, more than 90% of the substances are in plasma state.
