| 摘 要： | 无论是解算通风网路还是进行通风系统稳定性分析，都必须考虑自然风压的影响。当自然风压以能量源形式考虑时，必须将自然风压放置在网孔中适当的分支上，否则将导致计算结果的失真，或得出错误的风流稳定性判别式。本文给出一种在网孔中正确表示自然风压的方法，以保证网路解算结果的正确性和通风系统稳定性分析结论的合理性。

| Abstract: | It is necessory to take into account the effect of natural ventilating pressure whether for the resolution of ventilation network or the stability analy-sis of ventilation svstem. When the natural ventilation pressure is considered in the form of an energy source, the natural ventilating pressure must be put in a proper split of the meshes of the ventilation network, otherwise,the calculated results will not be true or a wrong discriminant for air flow stability will be obtained,This paper describes a method for correctly axpressing the natural vent-ilating pressure in the meshes of the ventilation network in order to ensure the correctness of resolution results and the reasonableness of stability analvsis of ven-tilation system. |
