A systematic method is developed to studY the classical motion of a mass point in gravitational gauge field. First, by using Mathematica, a spherical symmetric solution of the field equation of gravitational gauge field is obtained, which is just the traditional Schwarzschild solution. Combining the principle of gauge covariance and Newton's second law of motion, the equation of motion of a mass point in gravitational field is deduced. Based on the spherical symmetric solution of the field equation and the equation of motion of a mass point in gravitational field, we can discuss classical tests of gauge theory of gravity, including the deflection of light by the sun, the precession of the perihelia of the orbits of the inner planets and the time delay of radar echoes passing the sun. It is found that the theoretical predictions of these classical tests given by gauge theory of gravity are completely the same as those given by general relativity. 展开更多

The planetary geometries were studied at the moments of 92 strong earthquakes with a magnitude of more than 8 on the Richter scale (R8+) for the period from 1900 to 2011. Three main planetary schemes were specified, namely the schemes of the generalized Archimedes lever (gAL) and the Kepler conjunction (gKc), as well as a new geometry of the triangles of the remote signal catcher (cRS). It was discovered 22 gAL, 42 gKc and 28 cRS geometries, which are 23.9%, 45.7%, and 30.4%, respectively, from the total 92 studying cases. It was found that in some earthquakes;the planetary geometries are absolutely identical, which indicates the universality of the mechanism that caused the earthquake. The triggered effect does not depend on the distance between the planets and the mass of the planets, so the mechanism is identified as an inertial gravitational interaction. The triggered effect increases with the multiplicity of the ratio of distances between planets, as well as with pairwise planetary parallelism, which probably indicates about the wave nature of inertial effects. The triggering effect increases with increasing multiplicity of the ratio of distances between planets, as well as with pairwise planetary parallelism, which probably indicates about the wave nature of inertial effects. According to the Archimedes’ lever principle, the Third Law of Motion is changed by adding a few words. It is assumed that inertia is a special case of gravity, namely gravitational self-induction, which really depends, like any self-induction, only on the geometry of the task. 展开更多
