本文用632.8nm He-Ne激光束的衰减来研究反射冲击波后氢乙炔、乙炔乙炔、丁二烯、丁二烯和苯的混合气中碳烟的形成。实验在温度1500-2490 K，压力1.3-3.1 bar，总碳原子浓度（2.0-6.8）× 10 ~（17）atoms/cm ~ 3条件下进行。乙炔中加入分子氢可减少碳烟的生成。在二元烃类混合物中观察到了协同效应对碳烟形成的影响。实验观察结果进行了解释，使用详细的化学动力学模型。模拟中使用的反应机理由522个可逆反应和180个物种组成。计算结果表明，混合物效应主要是由乙炔加成反应的加速引起的。
Soot formation in hydrogen-, aliene-, and vinylacetylene-acetylene and acetylene-, aliene-, vinylacetylene-, and 1, 3-butadiene-benzene argon-diluted mixtures was studied behind reflected shock waves by monitoring the attenuation of a 632.8-nm He-Ne laser beam. The experiments were performed at temperatures of 1500-2490 K, pressures of 1.3-3.1 bar, and total carbon atom con-centrations of (2.0-6.8) X 1017 atoms/cm3. Theaddition of molecular hydrogen to acetylene resulted in the decrease of soot production. Synergistic effects on soot formation were observed in the binary hydrocarbon mixtures. The experimental observations were interpreted by using detailed chemical kinetic modeling. The reaction mechanism used in the simulations was composed of 522 reversible reactions and 180 species. The computational results revealed that the mixture effects are caused primarily by the acceleration of acetylene-addition reactions.
