摘　　要：通过修正Scott-Hinsleym风网解算方法的缺陷,提出了一种新的全回路调节方法。该方法通过使所有独立回路分支风压代数和的平方和最小化的方法,建立了通风网络解算优化模型,并用梯度法对该模型进行解算,获得了一种新的风网解算算法。该方法理论上考虑到了通风网络中存在固定风量分支的情况,可实现所有回路的调节,并可实现按需分配归零误差。This paper represents a new method hased on the improvement of the Scott - Hinsley method. In the method, a optimization model of a ventilating network is put forward hy taking the minimizing squared sum of algebraic sum of the ventilation pressure of all branches in a independent circuil about all independent circuits as object function, therefore a new algorithm of ventilation network optimization is obtained, The new method theoretieally gives consideration of existence of branches with fixed volume in a ventilation network, can carry out adiustment to all independent circuits, the balance error can be allocated by demand.
