For three weeks, they practiced and performed as the plane did parabolas climbing until it goes over the hump, creating 27 seconds of weightlessness-time to open luggage and release a zillion balls.

他们为此训练了3周, 在机开始抛物攀升, 直到已经平稳过关, 创造出27秒的失重状态后, 是时候打开行李, 开始一段震撼人心的表演了。

An orbit with an eccentricity greater than one is no longer an ellipse but a parabola if e is equal to one a hyperbola if e is greater than one.

偏心率大于 1 的轨道，如果 e 等于 1，它就不再是椭圆而是抛物，如果 e 大于 1，则是双。

Mathematically, the value of eccentricity varies between zero and one; with zero representing a circle and one transforming into another shape, called a parabola.

在数学上，偏心率的值在0和1之间变化，零代表一个圆，一个转换成另一种形状，称为抛物。

But because gravity makes the ball's trajectory a parabola, the air pushing against the ball changes directions as it flies.

但是因为重力使球的轨迹呈抛物，所以当球行时，推动球的空气改变了方向。

The orbit is now a hyperbola, which is similar to a parabola, but is even more open.

这种轨道是条双，类似于抛物，但更加开放。

All you need is a jetliner, a parabola and voila, you're weightless.

你需要的只是一架客机, 行个抛物, 然后, 你已经失重了。

An escape orbit is open — it doesn't come back — and is shaped like a parabola.

逃逸轨道是开放的——它不会回来——形状就像抛物。

Instead of a parabola that just goes like this.

而不是这样一个简单的抛物。

The Portuguese word comes ultimately from the late Latin noun parabola, meaning speech or parable.

葡萄牙语中的这个词最终源晚期拉丁语名词“parabola”，意思是演讲或寓言。

As the market's going parabolic due to speculative buying, that's a total parabola.

由于投机性买入，市场正在呈抛物式上涨，这完全是典型的抛物走势。

Used to play with the parabolas myself.

我过去常常玩抛物。

She was composed, Anthony perceived, of a succession of semicircles and parabolas, like those figures that gifted folk make on the typewriter: head, arms, bust, hips, thighs, and ankles were in a bewildering tier of roundnesses.

安东尼认为，她是由一连串的半圆和抛物组成的，就像有天赋的人在打字机上打出的那些数字：头部、手臂、胸部、臀部、大腿和脚踝呈令人眼花缭乱的圆形。

Directly it was suspected they would either kill you at once and save themselves further useless effort, or let you recover sufficiently so that your nerves had crept back to the other side of the parabola.

直接怀疑他们要么立即杀了你， 让他们省下更多无用的努力， 要么让你充分恢复， 这样你的神经就会回到抛物的另一边。

But since you're at a minimum, it kind of goes like a parabola, so it can be proportional to eta squared or potentially some higher order term.

但是由于你处于最小值，它有点像抛物，所以它可以与 eta 平方成正比，或者可能是一些更高阶的项。

The Greek mathematicians know the properties of the parabola and so could have directed the assembly of small mirror pieces into the parabolic shape.

希腊数学家知道抛物的性质， 因此可以将小镜子碎片组装成抛物形状。

Curving surfaceward in a sharply changing parabola, the pilot overcorrected and had to wait to gather downspeed and then overcorrect it again.

行员以急剧变化的抛物轨迹向表面偏移，修正过度，不得不等待减速后再一次过度修正。

And the trick here is that anything you throw into the air, neglecting air resistance, will travel in a perfect parabola.

这里的诀窍在于，忽略空气阻力时，任何抛向空中的物体都会沿着一条完美的抛物运动。

These ellipses were so stretched out, however, that they could be approximated to an open-ended curve called a parabola.

然而， 这些椭圆被拉得如此之长，以至于可以近似为一种称为抛物的开口。

There are 31 parabolas per flight.

每次行有 31 条抛物。

Or you could even think of it as a three-dimensional parabola.

或者你可以将其想象成一个三维抛物面。
