中文摘要：
这研究被进行调查中央规模燃烧的特征。电的电容断层摄影术(ECT ) 的技术被用来定位火焰位置并且在一间中央规模燃烧室监视相应于改变的空气 / 燃料比率的效果。燃烧现象包括点火，熄灭和不稳定的燃烧用 ECT 被设想了。保护 ECT 传感器免受高温度损坏的伤害的 metallization 的方法和使适应未知介电常数火焰监视的 ECT 的新奇刻度方法被显示了成功。同时，燃烧的电的自然和烃火焰的绝缘的特征被学习。在火焰介电常数和燃烧气体的州的参数之间的关系 preliminarily 被表明。
英文摘要：
This study was conducted to investigate the characteristics of meso-scale combustion.The technique of electrical capacitance tomography（ECT） was used to locate flame position and monitor the effect corresponding to varied air/fuel ratio in a meso-scale combustor.Combustion phenomena including igniting,quenching and unsteady combustion have been visualized using ECT.The method of metallization protecting ECT sensor from high temperature damage and the novel calibration method adapted to ECT monitoring of unknown permittivity flame have been shown to be successful.At the same time,electrical nature of combustion and dielectric characteristics of hy-drocarbon flame were studied.The relationship between flame permittivity and state parameters of combustion gas was demonstrated preliminarily.
