摘　　要：指出了多级压缩机等压力比设计理论缺陷 ,提出了变压缩多方过程指数非等压力比设计理论 ,推导出理论公式 ,并给出了图解和分析 ;分析了活塞式压缩机气缸缸径对压缩多方过程指数影响 。Theoretical defect of equal compression ratio design for poly-stage compressors is discussed.In fact, compressibility exponent of a stage of a multi-stage compressor is rarely same as others.So the therory on un-equal compress ratio design is developped,the theroretial equation on un-equal compression ratio design is given,the chart for un-equal compression ratio design is shown and demonstrated. Furthermore, the infection of cylinder diameter on compressibility exponent for a poly-stage compressor is analysed,and experiment data are given too.
