摘要： 使用几何光学的方法研究光跟引力场之间的相互作用,得到了在引力场中光的速度,从一个新的角度讨论了ReissnerNordström度规中光的偏折和雷达波延迟,从而验证了广义相对论.另外,几何光学的方法新颖简洁,在其他研究领域也有应用前景.最近讨论非常热烈的课题——强光在等离子体中传播的几何光学及度规光学问题——原则上是可以应用本文提供的新方法.

关键词: 坐标速度, Reissner-Nordström度规, 雷达波延迟, 弱场引力, 光线偏折

Abstract: Using the fundamentals of geometrical optics' method to study the interaction between the static field and the photon, the speed of photon in gravitational field is obtained and then the deflection of light and radar echo delay in Reissner-Nordström (R-N) field is discussed.General relativity is verified with a new approach.This method is novel and brief, and it is suitable to other fields.The study of the geometrical optics and metric optics about light propagation in plasma is very hot recently, in principle our new method can also be used in this field.

Key words: radar echo delay, weak gravitational field, Reissner-Nordström metric, deflection of light, coordinate velocity
