The results of the experiment showed that tungsten powder particle-size depends on the ertempature, flow of hydrogen, bed depth and pushing rate of boat.

结果表明，钨粉粒度与还原温度、舟装料量、氢气流量和推舟速度成线性关系。

The stainless steel powder becomes finer and the size distribution is narrower with the mass flow rate and pressure of gas medium increasing.

随着气体介质流量及压力的增加，所制备的不锈钢粉末粒度越小，粉末的分布更集中；

The effects of the air inlet flow rate and the rotor rotating speed on powder materials dispersion in turbo air classifier are investigated by the experiment.

通过实验研究涡流空气分级机分级中进口风速和转笼转速对机内粉料分散的影响。
