亚井博士说道：“我还发现了当有其他品种的蝴蝶在附近时，这些铜色蝶会以低频率时不时地合上翅膀”，那时他正打算弄清楚这其中的原因。

"I also found that she closed the wings at a lower rate when other butterfly species flew nearby," said Dr Ide. And he set about trying to find out why this might be.

结果表明，我国北部上空的西风急流（及相应的锋区）与澳大利亚的夏季风的低频变化有很好的一致性。

The results show that there is a good consistency between the low -frequency variations of the westerly jet (and its relevant front zone) over the Northern China and Australian summer monsoon.

通过饱和多孔岩石的低频亚共振试验，得到了饱和多孔岩石的内耗峰是典型的弛豫峰的结论。

From the experiments of low frequency sub resonance vibration for different fluid saturated rocks, the internal friction peak was found to be a typical relaxation peak.
