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

最后结果是，我几乎可以把这些省略部分填满。

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

至少不是一个标准圆形，而更像是一个拉长椭圆。

An ellipse is an asymmetrically shaped closed oval.

任何椭圆都是对称封闭椭圆形。

This ellipse has an important property called eccentricity.

椭圆有一个重要性质，叫做离心率。

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

" n" 进入" o" ，是一个省略。

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

偏心率衡量是椭圆与圆相比扁平度。

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，球轨道是个椭圆，相对以太阳为中心绕起来话有两个焦点。

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

当行星围绕恒星运行时，它会形成一个圆(或椭圆)。

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

牛顿预测水星轨道是椭圆，或者用家惯用词，“椭圆形”。

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

这份粗略文字记录还略去了三处，特朗普均为说话人内容。

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

焦点距离越远，椭圆受到挤压越。

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

同样要记住是，月亮绕球公转轨道是个椭圆。

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

它有两个点，称为焦点，作为一个椭圆联合中心。

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

不仅如此，月球绕球公转轨道是椭圆形。

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

相反，它们通常有一个圆形拉伸公转，也是椭圆。

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

椭圆是一种类似于被压扁圆形状。

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

a 是半长轴，或者说椭圆长轴距离一半。

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

它焦点是椭圆内描述其形状两个点。

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

简单说，离心率表示椭圆与正圆偏离程度。

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

b 是半短轴，或者说椭圆短轴距离一半。
