用直线树篱和指南针借助速端图和汉密尔顿矢量追踪行星的轨道
Tracing a planet's orbit with a straight hedge and a compass with the help of the hodograph and the Hamilton vector
摘要：
我们描述了一个几何方法跟踪一个行星的轨道使用其速度速端图，即行星的速度路径。该方法只需要一个直边，一个指南针，和速端图的帮助。我们还分析得到的速端图和一些功能的运动，可以从它获得。
英文摘要：
We describe a geometrical method for tracing a planet's orbit using its velocity hodograph, that is, the path of the planet's velocity. The method requires only a straight edge, a compass, and the help of the hodograph. We also obtain analitically the hodograph and some of the features of the motion that can be obtained from it.
