为了更好地了解更早时期的波动，我们需要使用代理记录。

To build up a better picture of fluctuations appreciably further back in time requires us to use proxy records.

研究人员指出，低频过程诸如河流流量和地下水水位的波动，通常不会对人类产生明显影响。

The researchers pointed out that low-frequency processes, such as fluctuations in stream flow and groundwater levels, would not usually be apparent to human populations.

So certainly we would expect to see that it has an effect in terms of seeing its wave-like properties.

所以我们当然可以预期,会看到波动性质的效果。
