作者在研究了Ｈ２对ＣＯ红外吸收系数影响的基础上。进一步研究了Ｈｅ，Ｎ２，ＣＨ４与ＣＤ４对ＣＯ超精细红外谱带吸收系数的影响．实验结果表明，单原子分子、非极性双原子分子和多原子分子ＣＨ４与ＣＤ４，对红外活性分子ＣＯ谱带吸收系数都会产生影响，吸收系数随气体分压的增大而增大．ＣＯ谱带吸收系数还受气体种类的影响，它随气体分子量的增加而增大，与气体分子量近似呈线形关系．
Based on the study of the influence of H2 on the infrared absorption coefficient of CO, The effects of He, N2, CH4 and CD4 on the absorption coefficients of CO superfine infrared bands were further studied. The experimental results show that the monomoatomic, non-polar diatomic molecules and polyatomic molecules CH4 and CD4 have an impact on the CO band absorption coefficient of the infrared active molecule, and the absorption coefficient increases with increasing gas partial pressure. CO band absorption coefficient is also affected by the type of gas, which increases with the gas molecular weight increases, and gas molecular weight approximately linear relationship.
