摘要 通过对火焰受到旋转磁场作用下微分方程的分析 ,确定在磁雷诺数Rm <1的情况下 ,由于磁场的旋转而产生的旋转火焰的稳定性条件 ,使人们更进一步地了解在磁场作用下旋转火焰燃烧的规律性。这样 ,就可以根据旋转磁场中旋转火焰的燃烧规律而了解实际火灾中火旋风的燃烧特性。从而在实际的火灾发生过程中有意识地对产生小的旋转火焰的某些特性加以控制 ,以避免火旋风的发生。这在实际火灾发生时 。 In this paper, by means of the study on the differential equations of fire whirl induced by a rotating magnetic field, the stable conditions of fire whirl in the rotating magnetic field can be determined. This can make us know more clearly about the burning rules of the fire whirl. At the same time, when a fire happens, some valid methods can be made to control it and prevent it from developing to fire whirl wind.
