Equation of Motion of a Mass Point in Gravitational Field and Classical Tests of Gauge Theory of Gravity

一个系统的方法被开发在保持的重力的计量器学习一个集体点的古典运动。由使用 Mathematica，首先，重力的计量器地的领域方程的一个球形的对称的解决方案被获得，它只是 traditionalSchwarzschild 解决方案。联合计量器协变性和牛顿的原则“运动的 s 秒法律，一个集体点在的运动的方程重力删除被推出。基于领域方程的球形的对称的解决方案和一个集体点的运动的方程在重力删除，我们能讨论严肃的计量器理论的古典测试包括由阳光的光的 thedeGection ，内部行星的轨道和传递太阳的雷达回响的时间延期的 perihelia 的领前。严肃的计量器理论给的这些古典测试的理论预言被一般相关性完全与那些一样给，这被发现。

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.
