Local thermodynamic equilibrium
局部热力学平衡
( 2 ) the emission spectra of laser ablation metal copper plasma were measured . the detailed mechanism of plume emission of cu plasma was qualitatively explained using a simple model based on excitation of atom and ion in plume arising from inelastic collision between the elemental species and electron with high kinetic energy . under the local thermal equilibrium model , the electronic temperature of copper plasma was deduced to be in the 104 scale by its emission lines
( 2 ) cu等离子体光谱：在420 570nm波长范围内观测了激光烧蚀cu等离子体的光谱和各发射谱线在等离子体中的空间分布；比较了激光能量对cu等离子体发射光谱、电子温度的影响；用局部热力学平衡( lte )近似，测得cu等离子体的电子温度为104k数量级；在不同背景气压下，观测了激光烧蚀cu等离子体光谱的空间分布。
