But it has smaller volume than displacement compressor at the same mass flow rate; and higher pressure ratio and efficiency than impeller compressor.
且尺寸体积远小于同流量的容积式压缩机，稳定性和压比也比同流量的条件下的叶轮式压气机有所提高。
At the same time, the mass flow rate and the heat flux density of each cross section of smoke flow were calculated as well.
同时，计算了烟气羽流各截面的质量流量和热流密度。
At the same time, the effect of liquid temperature, the mass flow and the flow direction on cooling effectiveness were obvious too.
同时表明，致冷液温、流量及液流走向，对致冷效能均有显著影响。
The mass flow of the gas pump is higher than the liquid pump under the same voltage, but back pressure of the gas pump is lower.
在相同电压驱动下气体无阀泵的流量要高于液体无阀泵，但气体泵的背压较低。
