Hide和Malin早在1970年就研究了地球引力场地磁场之间的相关性,把这一对具有重大意义的固体地球物理学研究的课题展示到了大家面前,引起了人们对地球各物理场之间的相互关系的极大关注。但是,Hide等在计算相关系数时,没考虑二者的带谐项以及地磁场四极子部分的高斯系数g_2~1和h_2~1,从而得出的结论是(整个)引力场与非偶极子磁场之间的相关系数为0.8381。我们知道,非偶极子磁场是地磁基本场的扰动部分,是偶极场与地核磁流体流动相 Hide and Malin studied the correlation between the magnetic field of gravitational field as early as 1970 and put the topic of solid geophysical research of great significance to everyone before us. The great concern of the interrelationships. However, when calculating the correlation coefficient, Hide et al. Conclude that the (whole) gravitational field is not related to the harmonic terms of the two and the Gaussian coefficients g_2 ~ 1 and h_2 ~ 1 of the quadrupole part of the geomagnetic field The correlation coefficient between the magnetic fields of the poles is 0.8381. We know that the non-dipole magnetic field is part of the perturbation of the basic field of geomagnetic field. It is the relationship between dipole field and ground magnetic fluid mobile phase
