曲线轨道是铁路线路的薄弱处所。

Curve railway is the weakest section in railroad.

但是曲线轨道并不像Carlson希望的那样陡峭。

But the curve trajectory isn't as steep as Carlson might like.

作为例子，我们计算了目视双星ADS 9446的双曲线轨道。

The hyperbolic orbit of and its mass the visual binary star ADS9446 is determined as an example.

So, the example that we took on Monday and that we ended with when we ended class, was looking at the 1 s orbital for hydrogen atom, and what we could do is we could graph the radial probability as a function of radius here.

周一我们,最后讲到了，粒子是氢原子１ｓ轨道，我们可以画出,这幅径向概率分布曲线。
