【摘要】 从人造卫星运动的资料分析得知,地心引力常数GM以每年2×10^-10的数量在减少,目前还不清楚,这是引力常数G减小,还是地球质量M减小引起的,本文从地球自转的长期变化方面分析来看,很可能是地球质量减小引起的。更多还原

【Abstract】 On the basis of the data analysis relating, to satellite motion it has been found that the geocentric gravity constant GM, where G is the gravitational constant, and M is the Earth mass, is in decreasing with a rate of -2×10^-0 per year. So far it is not yet clear which is the changing factor, G or M. According to the study on the long period term of rotation of the Earth the author of this paper holds that the decrease of the Earth mass is probably a primary factor led to this change.更多还原
