这个倒转过程能在古地磁记录中看到，这些记录被锁定在海底的岩石里和一些熔岩流中。

In addition, the computer model has produced three spontaneous reversals of the geomagnetic field during the 300,000-year simulation.

此外，计算机模型已经在30万年的模拟过程中产生了三次地磁场的自发倒转。

The stochastic nature of the process probably explains why the time between reversals on the Earth varies so much.

这个过程的随机性特征可能解释为什么地球磁场倒转之间的间隔变化会如此之大。

No one can say with any certainty whether this represents a fluctuation or whether it is a decrease, which will eventually lead to a reversal.

没有人能够确定地说出这是否会代表将最终导致倒转的磁场波动或减退。
