摘要

本文阐述了利用Maple平台的符号、数值和图形计算功能，在弯曲时空(主要是爱因斯坦方程的精确解)上进行测地线运动的图形化研究。完整地处理了零测地线在Schwarzschild解上的例子。用DEtools包在schwarz子坐标中直接绘制测地线曲线

The Use of Maple Platform for the Study of Geodesic Motion on Curved Spacetimes

The article illustrates the graphical study of geodesic motion on curved space-times (mainly exact solutions of Einstein equations) using the symbolic, numerical and graphical computation facilities of Maple platform. The example of null geodesics on Schwarzschild solution is completely processed. The geodesic curves are plotted directly using DEtools package in Schwarzs child coordinates
