对于不同的传压管径、传压管长度和腔室容积，得到不同阻尼的衰减振荡曲线以及过阻尼时呈单调衰减的回零过程曲线。

Then the different damped oscillation curves and over-damped monotonic decay curves can be obtained for various diameter and length of the pressured tube and various volume of the chamber.

此外，蜗杆的蜗杆槽深度随压力的增高而减少，在排气结束，星轮齿脱离单槽时，深度为零，故不存在余隙容积。

In addition, the worm and worm groove depth of the pressure increased, in the end, reduce exhaust gate-rotor from the single slot, depth is zero, it does not exist.
