中文摘要：
考虑和不考虑辐射作用，在宽广的拉伸率条件下，计算研究了组分CO、H2和N2摩尔分数分别为40％、30％和30％的燃料与空气（79％N2和21％O2）的详细层流对撞火焰结构．使用固有流形分析技术，考虑Leeds氮化学等，对Liu和Rogg发展的38步机理进行了修改．为研究辐射自吸收的作用，采用光细辐射模型（OTM）和窄带辐射模型（NBM），模型计算结果与Drake等的测量结果吻合良好．
英文摘要：
The detailed structure of laminar oppose＆flow diffusion flames with a fuel composition of 40% CO, 30% H2, and 30% N2 and an oxidizer composition of 79% N2 and 21% O2 has been calculated with and without considering effects of radiation over a wide range of stretch conditions respectively. Based on the 38-step mechanism developed by Liu and Rogg taking into account, the Leeds mechanism for the nitrogen chemistry and other needed channel reactions the mechanism was modified by using intrinsic manifolds analysis. To compare the effects with and without considering the radiation self-absorption, two radiative models, optically thin model （OTM） and narrow-band model （NBM）, were adopted in the calculations. The detailed model calculations show agreement with the previous experimental measurements by Drake et al.
