Its rotational axis is flipped upside-down, which means that the planet spins backwards.

它的旋转轴是颠倒的，这意味着行星会反向自转。

Spotting more complex substances was almost impossible because their rotational energy is scattered by their numerous bonds across a wide range of frequencies.

What we found in this whirligig toy is that it's one of the most efficient ways of converting your energy into rotational energy and that was the" aha" moment.

Where they get bigger and bigger and bigger as the steam imparts its energy on it to create that rotational force, which then creates a magnetic field through a generator to put electricity on the grid.

叶片逐渐变，蒸汽将能量传递给它，产生旋转力，从而通过发机产生磁场，将力输送。

So as I said, the tubes are really really light. That's a big part of it. Less rotational weight in the tires means that it just requires less effort to push the bike up a hill.

此，正如我所说的，内胎非常非常轻。这是很重要的原。轮胎的旋转重量越轻，意味着将自行车推上山坡所需的力气就越小。

One of the bizarre things about Venus, from a rotational dynamics perspective, is that it moves in retrograde motion, that is, it rotates in the opposite direction to the rotation of most other planets.

从旋转动力的角度来看，金星的一个奇怪之处在于它以逆行运动的方式运动，也就是说，它的旋转方向与多数其他行星的旋转方向相反。

Hip and shoulder joints use a ball-and-socket design that allow rotational movement, but the more flexible a joint is, the more unstable and fragile it is — which is one reason why you see so many dislocated shoulders and hip replacements.

髋关节和肩关节采用球窝设计，允许旋转运动，但是关节越灵活，它就越不稳定和脆弱——这也是为什么你会看这么多脱臼的肩膀和髋关节置换术的原之一。

And despite being in its 8th iteration of Marine rotational force, Darwin — not to mention speaking the same language, English — Australian troops have been ordered to avoid using slang around American counterparts.

尽管澳利亚海军陆战队已是第八次轮换（联合演习），更不用说他们说的是同一种语言——英语，但澳利亚军队仍被命令避免在美国同行面前使用俚语。

So far, using FAST-like large radio telescopes to conduct long-term timing observation of millisecond pulsars with extreme rotational stability is the only known method for effectively detecting nanohertz gravitational waves.

目前为止，使用类似FAST的型射望远镜，对具有极端旋转稳定性的毫秒脉冲星进行长期定时观测，是唯一已知的有效探测纳赫兹引力波的方法。

And poor posture, traumas, physical activity, and strong rotational movement can cause herniations where the intervertebral disc bulges out and compress the nerves or spinal cord.

不良的姿势、创伤、体力活动和强烈的转体运动，可引起椎间盘突出，即椎间盘膨突出于脊椎外，压迫神经或脊髓。

This is likely because of the rotational force of hook punches, compared to the linear force in football, which may make the brain trauma worse.

这可能是为钩拳的旋转力，而足球中运用的是线性力，这可能会使脑损伤更严重。

He said the same rotational pole data could be used to learn about possible causes of redistributed water over the past 100 years.

他说，同样的旋转极数据可以用来了解过去100年来水重新分配的可能原。

This calculation is a little bit complicated because it involves her moment of inertia, which is the rotational analog of her mass.

这个计算有点复杂，为涉及她的惯性力矩，这是她质量的旋转模拟值。

Heck, from the Field Museum, said the huge crash that formed the moon was a major event that changed Earth's rotational speed.

来自菲尔德博物馆的赫克表示，形成月球的巨碰撞是改变地球自转速度的重事件。

The researchers' findings added a whopping 28 seconds to Uranus's previously estimated rotational period. And hey, every second on Uranus is precious.

研究人员的发现将之前估算的天王星自转周期增加了整整28秒。天王星上的每一秒都弥足珍贵。

McCurdy is practicing rotational grazing, where he carefully moves this livestock around from one crop to another to manage soil health.

麦卡迪正在实施轮换放牧，他会仔细将这些牲畜从一片庄稼转移另一片庄稼以管理土壤健康。

In their rotational and orbital movements, stars and their satellites go from right to left.

天体的行星和它们的卫星公转和自转的运动，都是从右向左转。

We can also help a pitcher get better by giving them details like the rotational axis of the pitch.

我们还可以通过向投球手提供有关球场旋转轴等的细节信息，帮助他们表现得更好。

The galactic core's the rotational center you can't see because of the enter stiller dust it cannot be studied.

被遮住的区域是银河系核心的旋转中心，为这个区域布满了尘埃，我们无法研究。
