船在巨大的漩涡里面，而我们在漩涡里速旋转。

Technically, a tornado is just a violent rotating column of air coming out of the bottom of a thunderstorm.

从理论上来，风是从空中的雷暴延伸至地面而生成的极其强烈、速旋转的气柱。

Tornadoes are rapidly rotating columns of air that form inside storms that connect with the ground via a funnel of a cloud.

风是在大风内部形成的速旋转的空气柱，通过一个漏斗形的云状物和地面连接起来。

If the merger idea is correct, lots of new material flowing in a single direction feeds a black hole, driving the spin faster one way.

如果融合理论是正确的，来自同一方向的大量新物质流入可以促使黑洞成长，从而使得按照一个方向速旋转。

In the dairy, centrifugation machines spin milk at high speeds, forcing less dense fats to separate from the liquid and float up.

During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a " watchdog" timer expiration.

在上周五进行的旋翼速旋转测试中，由于“看门狗”计时器到期，控制测试的指令序列提前结束。

When the cosmos was very young and very hot, particles were whizzing around at high speeds and slamming into each other, creating other subatomic particles in the process.

当宇宙还很年轻、很热的时候，粒子速旋转并相互碰撞，在这个过程中产生了其他的亚原子粒子。

At high speed in slippery bends they provide only a few square centimetres of contact with the road, yet they help a driver steer safely around the corner.

当在光滑的弯道上速旋转时，它们与路面的接触面积仅有几平方厘米，却可以帮助司机在过弯处进行安全操控。

When all these things are in place, a vortex can develop enclosed by the storm, and forming a wide, tall tube of spinning air that then gets pulled upwards.

当所有这些东西都准备就绪的时候，一个涡旋在风暴包围中形成，继而形成一个宽大耸的速旋转空气柱，之后被向上拉动。

But when you spin it around really fast for a couple minutes, the centrifugal force pushes all the heaviest particles to the outside and they displace the less dense particles towards the middle.

但当你以速旋转它几分钟之后，离心力把所有最重的粒子推到外面，它们把密度较小的粒子推向中间。

Technically, a tornado is just a violent, rotating column of air coming out of the bottom of a thunderstorm, but it takes a lot to get that violently rotating column to come out.

从技术层面上讲, 风是从空中的雷暴延伸至地面而生成极其强烈, 速旋转的气柱，但需要猛烈旋转才能运动。
