- The experimental investigation was conducted for the fuel-circumferential-staging combustor with two domes to improve the lean blowout fuel air ratio. 摘要为降低贫油熄火油气比，对双头部燃烧室进行了燃油周向分级贫油熄火模拟实验研究。
- Results showed that the combustor with fuel-circumferential-staging could obviously improve fuel air ratio at lean blowout. 试验结果表明：与不分级燃烧相比，燃油周向分级燃烧能够显著降低贫油熄火油气比。
- Our products include multifunctional fittings such as gas air ratio control systems, and thermal management based on microprocessor-controlled automatic burner controls. 我们的产品包括多功能装置如空燃比调节系统和基于微处理器控制的自动燃烧器的热量管理。
- The jet characteristics under various injection conditions were measured by the schlieren photograph, and the overall excessive air ratio of the jets were calculated. 通过纹影照片得到了不同喷射压力和背压下的射流贯穿距离、射流锥角和射流体积随时间变化的规律，计算得到了射流内整体过量空气系数随时间变化的规律。
- The exhaust emission of HC and CO2 decreased with the increase of hydrogen fraction in fuel mixture, this would be due to the increase in H/C ratio and excessive air ratio. 在试验条件下，发动机HC和CO2排放浓度随混合燃料中掺氢比例的增加而下降，这是因为掺氢增加了混合燃料中H/C比值和混合气过量空气系数。
