摘　　要：从均压防灭火的需求出发,提出了节点风压灵敏度及其矩阵SP R的定义。根据通风网络节点分析法数学模型推导出了矩阵SP R的解析计算式,并将矩阵SP R应用于预测节点风压随分支风阻变化的变化趋势、均压防灭火中合理选择调压设施位置及估算风阻调节量。In this paper, the definition of the sensitivity and matrix SR of the node air pressure was put forward starting trom the needs of fire extinguishing by even air pressure, and the analytic formula of matrix Se was derived according to the mathematical model of the ventilation network node analysis method. The matrix S-PR 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.
