在与氩气等放电气体接触的两个电极之间施加足够高的射频电压来使放电气体击穿,产生正电荷离子和自由电子。在离子化气体即等离子体环境中的N_2等分子被离解为原子。正电荷离子、自由电子在电场的作用下分别加速移向阴极、正极。通过碰撞,加速离子与电子将其能量传递给原子,原子被激发。气态原子被激发以后,其外层电子辐射跃迁将发射特征辐射能,即特征光谱。通过对特征光谱进行分析,从而确定元素类别及其含量。 A sufficiently high radio frequency voltage is applied between two electrodes in contact with a discharge gas such as argon to break down the discharge gas to generate positively charged ions and free electrons. N 2 and other molecules in the ionized gas, the plasma environment, are dissociated into atoms. Positive charge ions, free electrons in the electric field under the action of accelerated move to the cathode, the positive. By collisions, accelerating ions and electrons to transfer their energy to atoms, atoms are excited. Gaseous atom is excited, the outer electron radiation transition will emit characteristic radiant energy, that is, the characteristic spectrum. By analyzing the characteristic spectrum, the element type and its content are determined.
