速率系数和亚稳态对氧的离化平衡和辐射损失的影响
THE INFLUENCE OF RATE COEFFICIENTS AND METASTABLE STATES ON IONIZATION EQUILIBRIUM AND RADIATION LOSSES FROM OXYGEN
【摘要】 本文依照定态日冕模型,采用不同速率系数的组合,计算氧的离化平衡和辐射损失。考虑了氧的三个砭稳态:类He离子OⅦis2s3S,类Be离子OV1s22s2P3P,类B离子OⅣ1s22s2P24P。计算亚稳态粒子占有数与基态粒子占有数之比随电子温度的变化。文中给出不同情况下,速率系数和亚稳态对氧的离化平衡和辐射能量损失的影响。
【Abstract】 Calculational results of ionization equilibrium and radiation losses for oxygen are presented as functions of electron temperature. These calculations are based on the corona model. In order to study the influence of rate coefficients on ionization equlibrium and radiation losses, we used several different formulae of rate coefficients, and included matastable states: He-like OVⅡ1s2s3S, Be-like OV1s22s2p3P,B-like OV1s22s2p24P.
