摘　　要：以计算机图象动态显示为手段，对△和Ｙ形网路的风网特征图进行动态变换。证明了△—Ｙ形网路变换的非等效性。这种变换存在着解的无穷性，并且仅适用于通风网路的结构和参数不变的状态。Dynamic variation of characteristic diagram of△ and Y type air network is made by means of image dynamic display of a computer. The nonequivalency of △-Y type network transformation was proved. This variation has infinite solution. It is only applicable in the invariant state of ventilation network structure and parameters.
