抛物线

By the detail discussion onthe hardware of the smooth path control system of single-chip microcomputer developed and the system software including new type continuous smooth path software, the analyzing of international standard program languageISO andthe attempt to developmental application in the smooth path control systemand experiment have been done, the description of the smooth path of the non-circular curive such as ellipse, hyperbola, parabola and their realignment has been realized by the way directly to input their parameters. The correctnesson the priciple and the method of the continuous smooth path control and the forthright on programing method hayed been proved by the experiment, new way to realize higher accracy continuous smooth path control has been developed.

Now according to Newtonian theory, some of them moved in hyperbolas or parabolas never to return; others moved in ordinary ellipses.

现在，牛顿理论认为，有一些彗星沿双曲线或抛物线运行，永远不再返回；另外一些彗星沿普通的椭圆轨道运行。

Does such 定点 also exist in parabolas, eclipses, and hyperbolas?

是否在抛物线、椭圆、双曲线同样也存在这样的定点？
