inelastic collision 【物理學】非彈性碰撞。

inelasticity

( 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等離子體光譜:在420 570nm波長范圍內觀測了激光燒蝕cu等離子體的光譜和各發射譜線在等離子體中的空間分布;比較了激光能量對cu等離子體發射光譜、電子溫度的影響;用局部熱力學平衡( lte )近似,測得cu等離子體的電子溫度為104k數量級;在不同背景氣壓下,觀測了激光燒蝕cu等離子體光譜的空間分布。

Elastic collision and inelastic collision are considered in oxygen molecule , nitrogen molecule by electron impart . the mail simulation results were as follow : ( 1 ) the variations of drift velocity and the average energy of electron with the e / n in o2 and n2 are obtained . the number of electrons for excitation , ionization , dissociation and dissociative ionization collision with the e / n and the energy of electron are analyzed emphatically 考慮了各種彈性和非彈性碰撞過程,在純氧氣、純氮氣中,給出了不同簡化場e n條件下的電子漂移速度和平均電子能量的變化;著重分析了激發、電離、分解及分解電離碰撞的粒子數隨e n 、電子能量的變化,同時計算了激發發射光譜的波長。
