The results show that the stiffness is dependent not only on the pressure and volume at static balance, but also on the change rates of efficient area and volume.
结果表明：空气弹簧的刚度不仅与其静平衡位置时的压力和容积有关，还与其有效面积变化率和体积变化率有关。
Sometimes, this increase can overcome the static pressure rating of the fan motor and reduce the volume of air through the unit.
有时候，这种增量可以克服风扇电机的静态压力，并减少系统中空气的容量。
It also contains fan curves defining volume or mass flow rate versus static pressure difference for selected industrial fans.
它也包含为了被选择的工业的未定定义相对于静态的压力差异的量或者大规模流量的未定曲线。
And adjustable speed the variable air volume air conditioning automatic control system saves energy through setting different static pressure values in different time periods.
变风量空调控制系统以变频调速为手段，分时段设定静压值以实现节能。
Finally, some major parameters such as cord Angle, initial inner pressure and additive volume were taken into account, which had remarkable effect on the air-spring's static performance.
最后考虑并研究了帘线角、初始内压和附加容积等主要参数对空气弹簧静态力学性能的影响。
When ordered, the configurations of the unit should be indicated, such as, the air volume, static pressure (outer engine), the total static pressure of the fan, quantity of cold and quantity of heat.
