试论行星磁场强度分布的成因

行星磁场强度的分布具有规律性,中间巨行星的强度值大,两侧类地行星和远日行星的强度值小。在类地行星和远日行星中,也是中间行星磁场强度值大,如地球和海王星。两侧行星磁场强度值小,如金星、火星、天王星和冥王星。水星磁场强度值比金星大是因为水星环较早的从A组星云环中分裂出来所致。行星磁场强度大小分布的规律性与星云环级式分裂、环体物质中聚即铁磁性物质较快中聚的规律性一致。所以,铁磁性物质多少,可能是行星磁场强度大小分布的一个主要原因。

On the Origin of the Intensity Distribution of Planetary Magnetic Fields

There are certain characteristics in the intensity distribution of the planetary magnetic fields. The magnetic field strengths are greater in the giant planets than in those planets at the far-end of the solar system. We observe a similar pattern inside the terrestrial and the far-out planets: the earth and Neptune both possess relatively greater magnetic strengths while Venus, Mars, Uranus and Pluto all have weaker magnetic fields. The intensity distribution of planetary magnetic fields, we find, is in conformity with the concentration of the Nebulous Ring mass in the middle, that is to say, the ferromagnetic material first accumulated in the middle quickly. Therefore we may conclude that the quantity of ferromagnetic material could be largely responsible for the distribution of intensity of the planetary magnetic fields.
