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。
