Abstract：In this paper, the definition of the sensitivity and matrix SPR of the node air pressure was put forward starting from the needs of fire extinguishing by even air pressure, and the analytic formula of matrix SPR was derived according to the mathematical model of the ventilation network node analysis method. The matrix SPR was then used for the prediction of the change tendency of the node air pressure with the branch air resistance, the rational choice of the pressure balance facilities location in fire extinguishing by even air pressure and the estimation of air resistance regulation.
