等离子体(又称电浆)是在固态、液态和气态以外的第四大物质状态,其特性与前三者截然不同。 气体在高温或强电磁场下,会变为等离子体。在这种状态下,气体中的原子会拥有比正常更多或更少的电子,从而形成阴离子或阳离子,即带负电荷或正电荷的粒子。气体中的任何共价键也会分离。 由于等离子体含有许多载流子,因此它能够导电,对电磁场也有很强的反应。和气体一样,等离子体的形状和体积并非固定,而是会根据容器而改变;但和气体不一样的是,在磁场的作用下,它会形成各种结构,例如丝状物、圆柱状物和双层等。 等离子体是宇宙重子物质最常见的形态,其中大部分存在于稀薄的星系际空间(特别是星系团内介质)和恒星之中。

plasma,也就是等离子体,等离子体是一种由 自由电子和带电 离子为主要成分的物质形态,广泛存在于 宇宙中,常被视为是物质的第四态,被称为等离子态,或者“超气态”,也称“电浆体”。
