1. Experimental study using hot wire anemometer is carried out for the vaned diffuser of a centrifugal compressor. The flow field data are taken and reduced. 建立了进行级环境下扩压器内部流场实验研究的数据采集和处理方法，并用热线风速仪进行了测量；
2. These diffusers include vaneless diffuser, vaned diffuser, low solidity diffuser and half-guide-vanes diffuser. 采用的扩压器包括无叶扩压器、叶片扩压器、低稠度扩压器和半高导叶扩压器。
3. The results also display the impeller's good hydraulic properties and the vaned diffuser's imperfect hydraulic properties and low efficiency. 计算结果还显示：潜油泵叶轮有较好的水力性能，而潜油泵导轮的水力性能是不完善的，效率较低。
4. These diffusers include vaneless diffuser, vaned diffuser, low solidity diffuser and half-guide-vanes diffuser. 采用的扩压器包括无叶扩压器、叶片扩压器、低稠度扩压器和半高导叶扩压器。
5. Vaned diffuser plays an important role in centrifugal compressor as it can improve the performance of compressor and broaden the operating range. 离心压缩机中，叶片扩压器对提高压缩机整机性能、拓宽有效运行范围发挥着举足轻重的作用。
