振动，它们总能更强烈地振动，更快地平移。

Vibrating, they can always vibrate harder, translate faster.

如果压缩机(12)或真空泵(10)非常强烈地振动，那么因此能够简单地修改驱动马达(14)的转动频率以防止共振效应。

If the compressor (12) or the vacuum pump (10) vibrate too strongly, the rotative frequency of the drive motor (14) can thus be simply modified to prevent resonance effects.
