行星磁场与卫星引力及其相对运动的统计关系

从知道某些天体具有磁场起，人们就对其磁场的起源提出种种解释，例如有电池说，转子说，化石说，发电机说等等。但由于这些学说都分别与某些观测事实相抵触而未被公认，因此星球磁场的起源一直是未能解决的命题。余先河先生提出，星球的磁场起源可能与所受的引力有关，行星的磁场强度正比于其所受卫星的引力；正比于卫星与行星的引力连线转动的相对角速度。本文对这两方面的命题分别进行了相关分析，得到其相关系数分别为：ｒ＝０．８４８１和ｒ＝０．８４２５，它们都在ａ＝０．０１的信度水平上相关。结果表明余新河关于行星磁场起源的设想是有基础的。本文还对其统计结果和可能机制进行了讨论。

The Statistical Correlation of the Planetary Magnetic Field with the Satellite Gravitation and Their Relative Motion

Sicnce some celestial bodies have been known to possess magnetic fields, a lot of explanations for their origin have been proposed, such as the battery theory, the rotator theory, the fossil theory and the dynamo theory. However those theorieshave not been acknowledged owing to their conflict with some observation facts so that the subject of the magnetic field origin of celestial bodies has not yet been solved. Mr. Yu Xianhe suggested that the magnetial field origin of a celestial body may be related to the gravitation effect, an d the plenetary magnetic field is directly prportional to their satellite gravitation and the angular velocity of the gravitinal line between the planet and the satellite. The statistical analysis for those viewpoints is presented in this paper. It is found that the suggestion has a statistical basis
