The influences of fluidizing gas flow rate, pressure, pressurizing gas flow rate and total conveying pressure drop on the solid-gas ratio and the solid mass flow rate were investigated.

分别在不同的输送差压、充压风量和流化风量等条件下进行了输送试验，考察操作参数对煤粉质量流量和固气比等气力输送特征参数的影响。

However, increase of heat transfer rate is less than that of air mass flow rate.

然而, 传热率的增加幅度要低于气流量的增加量.

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。

Moreover, the pressure and the mass flow rate ratio are steady. The stability of temperature can meet the demands of experimentation precision.

制冷系统的压力和流量的稳定性非常好，温度的稳定性能够满足实验精度要求。
