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

最后的结果是，我几乎可以把这些省略的部分填。

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

至少不是一个标准的形，而更像是一个拉长的。

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

同样要记住的是，月亮地球的公转轨道是个。

This ellipse has an important property called eccentricity.

有一个重要的性质，叫做离心率。

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

不仅如此，月球地球公转的轨道是形的。

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

就像开普勒曾指出的，地球的轨道是个，相对以太阳为中心起来的话有两个焦点。

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

当行星围恒星运行时，它会形成一个大()。

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是的，者用科学家惯用的词，“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。

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

相反，它们通常有一个形的拉伸公转，也就是。

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

它有两个点，称为焦点，作为一个的联合中心。

An ellipse with zero eccentricity would just be a regular old circle.

偏心率为零的就是一个普通的。

An ellipse is an asymmetrically shaped closed oval.

任何都是对称封闭的形。

The equation is a way to compare these axes to describe how squashed the ellipse is.

这个方程是比较这些轴来描述扁平度的一种方式。

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

b 是半短轴，者说短轴的距离的一半。

And as if they were cuboidal cells that got stretched tall, their nuclei also are stretched into an ellipse.

由于它们是立方体细胞，被拉伸得很高，它们的细胞核也被拉伸成形。

As eccentricity increases, the ellipse gets flatter and flatter until it just looks like a line.

随着偏心率的增加，会变得越来越平，直到它看起来像一条线。

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

偏心率衡量的是与相比的扁平度。

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

是一种类似于被压扁的的形状。

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

它的焦点是内描述其形状的两个点。
