摘　　要：实验采用红外辐射测温法测出了多孔陶瓷燃烧器中预混火焰沿气流方向的温度分布曲线。结果表明，燃烧器中的燃烧火焰与自由火焰相比，燃烧温度显著提高，验证了理论预测的这一特性；也说明利用红外测温能克服热电偶等直接测温的缺点，得到了温度变化的真实特性。The temperature distribution in flow direction of a premixed flame in a porous ceramic combustor is experimentally being measured by infrared radiation. Results show that the combustion temperature within the combustor is markedly higher than that of a free flame, confirming theoretical deduction. It also shows that the disadvantage of thermocouples, of having to contact the flame, can be overcome with infrared temperature measuring methods. Figs 5 and refs 8.
