查询词典 geophysics

It is a fundamental tenet of geophysics that the Earth's magnetic field can exist in either of two polarity states: a "normal" state, in which north-seeking compass needles point to the geographic north, and a "reverse" state, in which they point to the geographic south.

有一个基本的地理方面的T，T是什么呢？地球的磁场可以存在于任两个状态中的一个。一个是正常状态，在这个状态中，寻找北方罗盘指针指向地理的北方。还有一个是相反状态，在这个状态中，它们指向地理南方。
