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。
Moreover, the curve can represent hyperbolas and catenary exactly.
此外，它可以精确表示双曲线和悬链线。
And hyperbolic polynomial curves can represent hyperbolas exactly.
此外，它还能精确表示双曲线。
The families of hyperbolas for each transmitter pair can be directly plotted on maps, including corrections for known propagation anomalies.
各基站间的双曲线族可以在地图中直接绘制出来，甚至包括不规则传播导致的误差修正。
