摘　　要：本文探讨通风系统的特征图。特征图与网路图具有等价关系,它不仅能反映风网的节点关系、回路关系、割集关系、通路关系,还能反映每条风路的风量、阻力、功耗的大小;它既能反映通风系统的技术管理水平,又能反映通风防灭火的技术途径。This paper discussed a characteristic diagram of a ventilation system. The characteristic diagram has an equal value relationship with a network diagram. The characteristic diagram can not only reflect the joint and point relationship, cut and accumilation realtionship, and airway relationship in the ventilation network, but also can reflect the air flow, air resistance, power consumption of each airway. The diagram can reflect the technical management level of the ventilation system, also can reflect the technical access of ventilation, and fire fighting and fire proofing. There is no others can be replaced with the functions of the characteristic diagram. The so called characteristic diagram of the ventilation network is to use a square frame to present the airway in the ventilation network. The square frames are rowed and lined up base on a certain relationship. In the condition of same scale, the width of the square frame is the air flow of the airway, the height of the square frame is the resistance and the area of the square frame is the power consumption of the airway.
