摘要
探讨和估计了各种引力常数变化理论对地球角速度和日长变化的影响。各种引力常数变化理论包括了引力常数G随时间、空间以及速度变化等几个方面的影响。另外也估计了对地球自转角速度和日长变化产生的效应。其中有些研究对探讨地球自转变化也有启发意义。
The influence of the various theories of variation of gravitational constants on the secular variation of angular velocity and daily length of rotation of the Earth are investigated. The various theories of variation of gravitational constans include the aspects of the influence of the variation of gravitational constants with time, space, velocity, temperature and distance. The effects of the various theories of variation of gravitational constants on the rotation of the Earth are estimated. In which some effects are meaningful for investigating the theory of the variation of rotation of the Earth.
