摘　　要：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．The effects of IR nonactive gas He, CH4, CD4 and N2 on the aborption coefficients of the ultra-fine asorption bands of CO have been investigated. It Was shown that the absorption coefficients of CO increased as the fractional presure of these gases increased.Meanwhile. the effect of the absorption coefficients of CO caused by the mass of the gas has been mentioned.
