假设地球基本磁场可以由地球自转加速度激发。为了检验这种角加速机制是否符合实际,本文根椐角加速机制推测了所激发的磁场的各种预期性质,并且把它们和对地磁场的观测事实进行分析对比。检验结果显示,地磁场的变化和自转速度的变化之间具有共同的频谱,而且角加速机制所预期的磁场性质无论在结构上,还是在随时间变化上都与对地磁场的观测事实相符合,没有遇到一个反例,而且能够解释地球发电机假说所不能解释的某些现象,例如,地磁场倒转时间的不规则分布和磁极游移等。本文所建立起来的地磁场与地球自转速度变化之间的10种关系具有基本的意义,在研究地磁场的起源时应该思考和回答为什么会存在这些关系,这对于探索正确的地磁起源机制也许是有益的。
It is assumed that the Earth’s basic magnetic field can be excited by the Earth’s rotational acceleration. In order to test whether this kind of angular acceleration mechanism is realistic, this paper estimates the various prospective properties of the excited magnetic field by the mechanism of angular acceleration and compares them with the observation of the earth’s magnetic field. The test results show that there is a common spectrum between the variation of the geomagnetic field and the variation of the rotation speed, and that the magnetic properties predicted by the angular acceleration mechanism are in accordance with the observation of the geomagnetic field both in structure and in time , Did not encounter a counterexample, and could explain some of the phenomena that can not be explained by the earth-generator hypothesis, such as the irregular distribution of the geomagnetic field reversal time and the magnetic pole migration. The ten kinds of relations between the geomagnetic field and the variation of the Earth’s rotation speed have the basic meaning. When studying the origin of the geomagnetic field, we should think and answer why these relationships exist. This may be the reason for exploring the correct geomagnetic origin mechanism benefit.
