Ensure the college and university teachers" main status in teaching. 6. reform the personnel administration system of colleges and universities.The unique features of this paper are: 1. This thesis, through analyzing the disorderly flowing in college and university teachers, revealed the connotation of the rational and orderly flowing of teachers. It"s unique among the same research. 2. This thesis, through applying the knowledge of higher pedagogy, educational economics, educational administration and educational sociology, etc. made a macroanalysis on the flowing of college and university teachers. Its distinctive from other papers which only focus on the phenomena and microanalysis. 3. This thesis, based on theoretical studies, put forward several practical measures for bringing about the rational and orderly flowing of college and university teachers. It puts attention on combining theoretical research with practical research.

本文的创新点在于：1、通过分析高校师资流动中的无序现象，揭示了高校师资合理有序流动的内涵，这一点在同类研究中是没有的；2、能够综合运用所学过的高等教育学、教育经济学、教育管理学和教育社会学等知识，从宏观上系统深入地研究了我国高校师资的流动问题，有别于其他的现象研究和微观研究；3、本文在理论研究的基础上对促进高校师资的合理有序流动提出了一系列有实践指导意义的对策措施，注重理论研究与实践研究相结合。

Comparison between the velocity distributions at the different flow rate conditions showed that increasing the flow rate was help to improving the velocity distribution. The periodic mean field on r-6 plane at different axis positions showed that the flow within the vaned diffuser, especially within the inlet region, was periodic unsteady when impeller located at the different circumferential position, just as the flow within the vaneless diffuser.

有叶扩压器内平均流场的分析表明，在定常流动的假设下，不同流量工况下有叶扩压器的内部流动也呈现为沿轴线向后盘方向推移流动状况逐渐恶劣的分布规律，表明二元叶片构成的平行直壁有叶扩压器对轴向不均匀流动的掺混作用仍然不大。
