摘要
用无限阶突变（ＩｎｆｉｎｉｔｅＯｒｄｅｒＳｕｄｄｅｎ（１ＯＳ））近似方法系统计算了ＣＯ２－Ｎ２，ＣＯ２－ＣＯ２混合气体中ＣＯ２分子在２９６－１２００Ｋ温度下转动量子数从１到３０的谱线压力展宽半宽度。计算过程中各系统的相互作用势采用改进的Ｂｕｃｋｉｎｇｈａｍ模型势。得到的结果和现有结果符合较好。
Pressure-broadening coefficients for CO 2 molecule have been calculated with the infinite order sudden (IOS) approximation. Systematic calculations of CO 2-N 2, CO 2-CO 2 broadenting coefficients in the 296-1200K temperature range are presented. In these calculations, the modified Buckingham potential is used. It is shown that our calculated results are satisfactory and thus provide basic data for plume of high speed vehicles.
