详细测定了带有笼式减阻杆件的高效旋风器内的气流场，对增设减阻杆件前后的器内流场做了对比，指出了置有这种减阻装置的旋风器的流场特点，简要分析并讨论了这种减阻方式的降阻机制。
The airflow field in a highly efficient cyclone with a cage drag reducing rod was measured in detail. The flow field before and after the addition of the drag reducing rod was compared. The flow of the cyclone with this drag reducing device Field characteristics, a brief analysis and discussion of the drag reduction drag reduction mechanism.
