Runge-Lenz矢量在解行星绕日问题中的作用

EFFECT OF THE RUNGE-LENZ'S VECTOR IN THE PROBLEMS OF THE PLANETS MOTION

本文讨论了Runge－Lenz矢量的性质，并利用它求解经典情况下和狭义相对论情况下的行星绕日问题．

The behaviours of the Runge -Lenz's vector are discussed in detail. By means of the Runge -Lenz's vector the problems of the planets motion around the sun are solved in classical and relativistic cases.
