摘　　要：在厘清容积系数β值物理含义的基础上,运用波义耳定律进行公式变换,并对比新旧两版标准图集中的设计参数,指出工作压力比α此参数在消防给水稳压设备选型计算中存在应用误区;推导得出各不同“压力比”定义下,所对应的正确“容积比”公式和气压罐“总容积”公式。On the basis of clarifying the physical meaning of the volume factor β,the formula transformation is carried out by using Boyle’s law.In addition, the comparison between the design parameters in the old and new standard atlas is conducted to point out the misapplication of the working pressure parameter αin the selection and calculation of the fire water supply voltage stabilizing equipment.On top of that, the correct "volume ratio" formula and the "total volume" formula of the pressure tank corresponding to different "pressure ratios" are derived.
