用梯度法解算矿井通风网络

通过修正Scott—Hinsleym风嘲解算方法的缺陷．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。

An improved optimization algorithm for solving ventilation network by gradient method

This paper represents a new method based on the improvement of the Scott-Hinsley method. In the method, a optimization model of a ventilating network is put forward by taking the minimizing squared sum of algebraic sum of the ventilation pressure of all branches in a independent circuit about all independent circuits as object function, therefore a new algorithm of ventilation network optimization is obtained. The new method theoretically gives consideration of existence of branches with fixed volume in a ventilation network, can carry out adjustment to all independent circuits, the balance error can be allocated by demand.
