摘要：

地球磁场多次发生南北(正负)磁极位置的变换,这已为大家所公认。但造成这种异常现象的原因,则是迄今未能很好解答的一个难题。应用分形混沌理论对地球磁极倒转进行了分析,认为发生地球磁极倒转时间段在时间轴上具有分形分布的性质;地球磁场系统通过不断与外界交换物质和能量,维持一种空间或时间的有序结构。地球磁场极性的随机倒转具有混沌运动的自逆转特性,混沌理论给地磁极性倒转提出了一个简明的动力机制解释。

Abstract:

 It is generally acknowledged that geomagnetic polarity has reversed many times in geological history. However, the causes have been unknown up to now. The fractal and chaos theories have been applied to analyzing the phenomenon in geomagnetic polarity reversal. The temporal intervals of geomagnetic polarity reversal have the characters of fractal. The system of earth magnetic field maintains a sort of temporal or spatial order structure by exchanging substance and energy with outside continuously. Random of reversal geomagnetic polarity has the selfreversion characteristic of chaos and chaos theory gives a simple and clear explanation for the dynamic cause of geomagnetic polarity reversal.
