摘　　要：介绍燃烧中离子产生与复合原理。以静电探针分别测量酒精喷灯预混火焰和航空煤油、酒精小油盘扩散火焰的电位和离子电流。试验结果揭示了燃烧状态和火焰电位分布的关系,即燃烧比较充分的区域带单一电荷,酒精和航空煤油均带负电;火焰内焰附近电荷密度大,火焰外部电荷密度小。The production and complex of ion during the combustion was introduced. Using electrostatic probe method to measure the potential and ion current of the premixed flame alcohol burner and the small oil pan diffusion flame of aviation kerosene and alcohol, respectively. The results showed that there is a close relationship between the potential distribution and combustion state of the flame, sufficient combustion area with a single charge, and alcohol and aviation kerosene are negatively charged; charge density is high in the flame and low at the edge of flame.
