Air compressionratio is in absolute pressure calculation.
空气的压缩比是在绝对压力计算的。

Finally, with the air of freedom multiplied by the number of air compressionratio that the pressure can be drainage, to determine choose which kind of air compressor.
最终,用自由空气的数量乘以空气的压缩比即可得出排水所需的压力,以确定选择哪种空压机。

The present study shows that there is a critical seal pressure which is only related to the compressionratio and the friction coefficient, but does not depend on the radius of the elastomer ring.
