So what ends up happening is that I could almost fill in the ellipses.

最后的结果，我几乎可以把这些省略的部分填满。

For one thing, it's not a perfect circle, it's quite an elongated ellipse.

至少不个标准的圆形，而更像个拉长的椭圆。

An ellipse is an asymmetrically shaped closed oval.

任何椭圆都对称封闭的椭圆形。

This ellipse has an important property called eccentricity.

椭圆有个重要的性质，叫做离心率。

The " n" goes into the " o" , an ellipses it's called.

" n" " o" ，个省略。

Eccentricity measures how flattened an ellipse is compared to a circle.

偏心率衡量的椭圆与圆相比的扁平度。

As Kepler showed, the earth's orbit is an ellipse, with the sun at one of the two focal points.

像开普勒曾指出的，地球的轨道个椭圆，相对以太阳为中心绕起来的话有两个焦点。

As the planet orbits the star, it makes a big circle (or ellipse) .

当行星围绕恒星运行时，它会形成个大圆(或椭圆)。

Now, Newton predicted that the orbit of Mercury was an oval, or as scientists like to say " an ellipse."

牛顿预测的水星轨道椭圆的，或者用科学家惯用的词，“椭圆形”。

The rough transcript also contains ellipses at three points where Mr. Trump is speaking.

这份粗略的文字记录还略去了三处，特朗普均为说话人的内容。

The further apart the foci are, the more squashed the ellipse is.

焦点距离越远，椭圆受到的挤压越大。

Remember too that the Moon's orbit around the Earth is an ellipse.

同样要记住的，月亮绕地球的公转轨道个椭圆。

It has two points, called foci, which act as a combined center for an ellipse.

它有两个点，称为焦点，作为个椭圆的联合中心。

Not only that, the Moon orbits the Earth on an ellipse.

不仅如此，月球绕地球公转的轨道椭圆形的。

Instead, they generally have a stretched version of a circle, which is technically called an ellipse.

相反，它们通常有个圆形的拉伸公转，也椭圆。

Well, an ellipse is a shape that resembles a kind of squashed circle.

椭圆种类似于被压扁的圆的形状。

Well, a is the semi-major axis, or half the distance along the long axis of the ellipse.

a 半长轴，或者说椭圆长轴的距离的半。

Its foci are two points within the ellipse that describe its shape.

它的焦点椭圆内描述其形状的两个点。

Simply put, eccentricity tells how much the ellipse deviates from a perfect circle.

简单地说，离心率表示椭圆与正圆的偏离程度。

And b is the semi-minor axis, or half the distance along the short axis of the ellipse.

b 半短轴，或者说椭圆短轴的距离的半。
