【摘要】 本文运用数学分析方法建立了局部通风系统设计的新的数学模型,阐述了以此模型为基础的各种条件下局部通风系统设计方法。据此模型编制的计算机程序不仅可用于局部通风系统设计,而且还可用于分析风筒漏风,考察实际局扇的通风效率,因而具有多功能性。文中所给实例显示了程序的可行性。更多还原

【Abstract】 A new mathematic model is established by mathematical analysis for the designing of localized ventilation systems, and hence computer programs for this purpose under different conditions. The programs can also be used in the analysis of air leakage in ventilation ductings and the ventilation efficiency of localized fans. It is shown by the case study that these programs are applicable更多还原
