elliptical

But the general solutions call for a elliptical orbit.(但是，一般的解决方法，还是需要一个椭圆轨道。)

The Moon's elliptical orbit means its distance from the Earth is not constant.(月球椭圆型的轨道意味着它到地球的距离是变化着的。)

It is more of an oval, it is elliptical.(它更像是一个椭圆形的。)

And here you have an explanation of an elliptical motion which is amazingly simple.(关于椭圆型运动的解释，是那么得简单明了。)

To select the outer circle, create an elliptical selection around the circle.(要创建其外圆，要创建一个近似正圆的椭圆。)

It's always negative. Okay, later in the course we will cover elliptical orbits.(总是负的，好吧，以后的课，我们会讲椭圆轨道。)

But elliptical galaxies seem to be simpler.(但椭圆星系似乎更简单。)

Select the Elliptical Marquee Tool (m) and make a selection over the divider line.(选择椭圆选框工具(M)然后在分割线上面画出一个椭圆。)

Elliptical galaxies are shaped as their name suggests.(椭圆星系的形状正如它们的名字所述。)

Newton also proved incidentally that a vortex could not generate elliptical motion.(牛顿也证明了漩涡能产生椭圆运动纯属偶然。)
