摘要/Abstract

摘要： 推广了最小光程原理. 假定如果选取全局时间对准的坐标系, 即度规场满足 g₀i=0, 则光的真实路径使坐标时差取极小值. 据此重新得到光经过太阳表面的引力偏折角α=4GM/r=1.75″, 与假定光沿测地线运动导出的结论相同. 这实质上是在广义相对论条件下, 对不存在超光速粒子的有力支持. 此外, 还提供了一种计算光传播路径的方法.

Abstract: The minimum time principle was generalized. It is assumed that in global time zeroed coordinate, which fits g₀i=0, the optical path makes the coordinate time interval minimum. According to this assumption, the deflection angle of light pass by the sun surface is α=4GM/r=1.75″, which is the same as that obtained before. This is essentially a sustaining of the no super-light velocity principle in general relativity. The basic assumption about the optical behavior is proposed, so it is totally a new theory. A method was given in calculating the optical path, which may be helpful for studying the light transition in cosmic.

Key words: gravitational deflection, minimum time principle, super-light velocity, Schwarzschild field
