地磁Z分量日变“低点位移”异常成因分析
|
摘要
本文基于对地磁Z分量日变"低点位移"异常和太阳静日变化内外源场等效涡旋电流体系时空演化特征的分析,提出了"电磁炉效应"假说,以解释地磁Z分量日变"低点位移"异常的成因。本文认为,起源于地球内部和外部涡旋电流体系所产生的太阳静日变化Sq,作为一个持续的交变磁场,切割地壳深部的高导低速层,形成涡旋电流并产生热能,致使高导低速层温度和压力不断上升,最终突破临界状态产生物质相变,引起电导率快速变化,使内外源场单个等效涡旋电流体系分解成两个或多个涡旋电流体系,进而引起地磁Z分量日变的"低点位移"异常。
This paper analysed the characteristics of spatio-temporal evolving of low-point displacement anomaly and the intrinsic and extrinsic equivalent eddy electric current system of the Earth,and proposed the "electromagnetism effect of stove" to explain the cause of low-point displacement.Solar quiet daily variation(Sq),originated from the intrinsic and extrinsic eddy electric current system of the Earth,as an ongoing and alternating magnetic field,cutting the high conducting and low velocity block in the deep of crust,produces the eddy electric current,and creates heat energy.The heat energy results in the unceasingly rising of temperature and pressure,finally has the material phase transition,and causes the conductivity change,and also leads the eddy electric current system to evolve from single eddy electric current system to double and more eddy electric current system.This might be the cause of low-point displacement anomaly in daily variation of Z component of geomagnetic field.
