一、物质的第四态——等离子体我们知道,物质通常处于三种聚集态,即固态、液态和气态,随着温度的变化,物质的三态之间可以互相转化。如果温度升高到104K甚至105K,分子间和原子间的运动十分剧烈,彼此间已难以束缚,原子中的电子因具有相当大的动能而摆脱原子核对它的束缚,成为自 First, the fourth state of matter - the plasma We know that the material is usually in three aggregates, that is, solid, liquid and gas, with the temperature changes, the three substances can transform each other. If the temperature rises to 104K or even 105K, the movement between molecules and atoms is very intense and it is hard to be bound with each other. The electrons in the atom get rid of the bond of the nucleus because of the considerable kinetic energy and become
