本论文在重新评估法拉第力线的基础上,提出了真实性存在的引力力线,有被拉伸和收缩的拓扑物理特征,从而考虑在球体旋转的情况下,作用于球体的引力线很可能存在一个旋转径向的拉长和收缩不对称过程,从而造成引力距差,引起球体的旋转径向... 本论文在重新评估法拉第力线的基础上,提出了真实性存在的引力力线,有被拉伸和收缩的拓扑物理特征,从而考虑在球体旋转的情况下,作用于球体的引力线很可能存在一个旋转径向的拉长和收缩不对称过程,从而造成引力距差,引起球体的旋转径向前后引力不对等,而产生了引力距离差旋转力矩,使地球等可以持续性连续性获得旋转扭力,而保持了地球自转的角动量来源。并通过计算得出,地球旋转一圈时得到的扭力为4.775964493 &#215;1016 N,其结果和利用其他方法得到的值基本相同。 展开更多

By calculating the azimuth, phase angle and change rate of tidal force, and contrasting their rupture types, we find that in 6 of 11 reverse faulting earthquakes, the angles between the direction of the horizontal tidal force and compressive principal stress are within 33°, the vertical phase angles of all 8 strike-slip earthquakes are in the upward peak section and the vertical phase angles of two extensional normal faulting earthquakes are in the downward peak section. According to the above statistics, the mechanism of tidal force triggering of the Wenchnan Ms8. 0 Earthquake and its strong aftershocks is discussed. 展开更多

We present Finslerian perturbation for the ∧CDM model, which breaks the isotropic symmetry of the universe. The analysis on the Killing vectors shows that the Randers-Finsler spacetime breaks the isotropic symmetry even ff the scalar perturbations of the FRW metric vanish. In Randers-Finsler spacetime, the modified geodesic equation deduces a modified Boltzmann equation. We propose a perturbational version of the gravitational field equation in Randers-Finsler spacetime, where we have omitted the curvature tensor that does not belong to the base space of the tangent bundle. The gravitational field equations for the gravitational wave are also presented. The primordial power spectrum of the gravitational wave is investigated. We show that the primordial power spectrum for super-horizon perturbations is unchanged. For sub-horizon perturbations, however, the power spectrum is modified. 展开更多
