Also known as axial tilt or obliquity.

也被称为转轴(axial tilt)(obliquity)。

This is known as the Earth's axial tilt, or obliquity.

这也被称作“轴”。

So this right here is my ramp.

至於这边这个就先假设它是30度。

And this angle right over here, let's just go with 30 degrees.

至於这边这个就先假设它是30度。

Earth's tilt could exceed 45 degrees at times in this scenario spinning on its side.

在这种情况下，地球有时可能会超过45度，向一面旋转。

Only big moons would cause enough of a dip in brightness to be detectable with today's instruments.

只有大卫星才会造成足够光亮，从而被现在仪器探到。

Depends on when we have these large dips in the jet streams, placement of the high pressure and low pressure.

取决于喷射流大，高压和低压位置。

If the two stars are similar, say both like the Sun, then the two dips look very similar.

如果这两颗恒星很相似，比如说都像太阳，那么这两次看起来就非常相似。

But if one star is much brighter than the other, then the two dips look very different.

但如果其中一颗恒星比另一颗亮得多，那么这两次看起来就非常不同。

A dip is a small hole in the road.

是道路一个小洞。

Voices and the dip of paddles out upon the river?

声音和桨在？

The Moon holds that tilt steady. The various gravity forces that are exerted tend to act in a way that holds that steady.

月球一直保持着一个。在万有引力作用下始终保持在一个固定。

Measuring those dips helped us locate a lot of these planets in the first place.

量这些首先帮助我们找到了许多这样行星。

So it doesn't go straight out of the Earth's atmosphere like this, it actually comes in at an inclination like this.

所以它并不是像这样直接脱离大气层，而是以这样进入大气层。

However, perhaps the most catastrophic effect that would happen without a moon would be the extreme change in Earth's axial tilt.

然而，在没有月球情况下，最具灾难性影响可能是地球轴心极端变化。

You have the date of the impact, the time of the impact, the orbital inclination, and you can make a map.

你有撞击日期，有撞击时间，有轨道，你就可以绘制地图了。

She pointed to a chimney just visible over the dip of the pasture below the wood.

她指着一个烟囱， 烟囱就在树林下面草地。

On the other hand, Slalom and Giant Slalom challenge the skier's agility, featuring sharp turns and big dips.

另一方面，回转和大回转挑战滑雪者敏捷性，具有急转弯和大特点。

Additionally, the eight known major planets of the solar system currently orbit the sun tilted by six degrees compared to the sun's equator.

此外，太阳系中已知 8 颗大行星目前围绕太阳运行，与太阳赤道相比，它们为 6 度。

As it happens, a large dip in the jet stream allows very cold air to spill into the U.S. That's the cold air you feel.

碰巧是，高速气流中一个大会让非常冷空气进入美国，这就是你感觉到冷空气。
