We need to know if Singer's findings hold true for magnetic field reversals in general.

我们需要知道辛格的研究结果是否适用于一般的磁场反转。

However, a recent study may help researchers better understand how long and how complicated Earth's magnetic field reversals really are.

然而，最近的一项研究可能有助于研究人员更好地理解地球磁场反转究竟持续了多长时间以及到底有多复杂。

There isn't any evidence to suggest that magnetic field reversals in the past have led to any mass extinctions.

没有任何证据表明过去的磁场逆转导致了大规模灭绝。
