| 摘 要： | 通过理论分析和实验研究,得到了固定磁场作用下火焰的烟尘和形状特性随磁感应强度变化的关系。对于油池扩散火焰,当其在固定磁场的作用下,火焰中的烟尘份额会随磁感应强度的增加而减小,火焰的温度会有所升高,火焰的形状也会随磁感应强度的变化而发生不同程度的改变,这不仅与磁场的强度有关,而且与火焰本身的燃烧特性也有一定的关系。

| Abstract: | By the theoretical analysis and experimental study,the soot concentration and flame formation were obtained.For an oil-pond fire,when the intensity of magnetic field rises,the soot concentration decreases,and the temperature of the flame increases.The formation for the flame will also change,but mainly with relation of only the intensity of magnetic field,but also the combustion characteristics of the flame itself. |

| Keywords: | Magnetic field diffusion flame soot concentration temperature flame diameter |
