摘　　要：简要论述局部扇风机 (轴流式通风机 )产生不稳定工况的原因和变化规律 ,提出以分流器消除风机特性曲线驼峰区段、使其工作运行稳定的技术措施。The reason and changing law of unstable operating mode of a local fan is briefly described in the paper. The technical measures are given out by which the hump zone of characteristic curve of the local fan can be eliminated using a current divider and the operaiting stability of the fan can be improved.
