英文摘要	The efficiency parameters are studied in this paper for evaluating the compression quality of the inlets with different compression degrees and assessing different design methods. Self consistency is proposed for the efficiency parameters, based on two mathematically derived efficiency parameters, entropy rise coefficient and compression quality efficiency. Two efficiency parameters are then examined for equal intensity shocks system to show their capabilities in characterizing the quality of compression system with different compression degrees, and representing the average compression efficiency of the entire inlet. And the process efficiency and compression quality efficiency are compared in the Mollier diagram to afford a clear understanding of their difference in evaluating the overall and the local compression efficiency.
