This has absolutely no tangential velocity.

这绝对没有切向度。

Her connection to this case is tangential, at best.

她与本案最多也就是一点间接牵涉而已。

Let's start with why is it a big deal to make it… stay tangential.

让我们首先谈谈为什么让它… … 保持切线是一件大事。

But we can also describe an object's rotation in terms of its tangential velocity.

我们也可以一半 以切向度表示物体的旋转。

In fact, its tangential velocity will be equal to its angular velocity, times the radius.

事实上，它的切向度将是 等于它的角度乘以半径。

Because, to get its total velocity, you add the translational velocity to the tangential velocity.

因为要找到它的总度，我们 度到切向度。

So, like linear velocity, tangential acceleration depends on the distance between the point and the center of the object.

因此，与线度一样，切向度取决于点与物体中心之间的距离。

And we know that in general, the magnitude of tangential velocity is also equal to the radius, times the angular velocity.

而我们知道，一般情况下，切向度的大小也等于半径乘以角度。

Because at the bottom of the wheel, the tangential velocity is pointing opposite to the direction the wheel is rolling in.

因为在轮子底部，切向度表示 反转车轮运动的方向。

But there’s also tangential acceleration, which describes whether an individual point on a rotating object is speeding up or slowing down.

但也有切向度，它描述了旋转物体上的单个点是在还是在减。

Cal's ballpark suggestion here is to have at least two sources for each main point in your thesis, and at least one for any tangential or non-crucial points.

卡尔的大致建议是，在你的论文中，每个主要观点至少要有两个支撑，且任何切题或非关键的观点至少有一个支撑。

So, at any given moment, each of those points will have a tangential velocity that depends on the path it moves through -- specifically, the radius of that path.

因此，在任何给定时刻， 这些点中的每一个都会有一个切向度，该切向度取决于它移动经的路径——具体来说， 就是该路径的半径。

But the bottom of the wheel won’t be moving at all … because its total velocity is its translational velocity minus the tangential, since they’re moving in opposite directions.

但是轮子的底部根本不会移动… … 因为它的总度是它的平移度减去切向度， 因为它们在相反的方向上移动。

The previous dating of the africanus and prometheus fossils at Sterkfontein and other sites in South Africa led to them being regarded as tangential to the main, east African story of human evolution.

之前在斯泰克方丹和南非其他地点发现的非洲人和普罗米修斯化石的年代，导致它们被认为与人类进化的主要东非故事无关。

But we can also describe an object’s rotation in terms of its tangential velocity. This is the same type of velocity we used when we talked about the physics of uniform circular motion.

但我们也可以根据物体的切向度来描述物体的旋转。这与我们在讨论匀圆周运动物理学时使用的度类型相同。

So Sarah, there's one thing we haven't talked about here, which is slightly tangential, but it's the office-spouse friendship, which is something that I'm obsessed with. Have you ever had an office spouse?

所以莎拉，有一件事我们在这里没有谈，有点离题，但这是办公室配偶的友谊，这是我很着迷的事情。你有办公室配偶吗？

And we can only see that we've been following this year, how much those companies have grown, how the stock prices of NVIDIA, NVIDIA, and any other firm even tangential to AI is continuing to surge.

我们只能看到，我们今年一直在关注这些公司增长了多少，英伟达、英伟达以及其他任何与人工智能无关的公司的股价如何持续飙升。

Consequently,   none of Shakespeare's letters that he might have written during his lifetime have survived and we  are left reliant on extracting impressions about who he actually was on a personal level from  his plays, poems and other tangential sources.

因此，莎士比亚生前可能写下的所有信件都没有保存下来，我们只能从他的戏剧、诗歌和其他无关的资料中提取关于他个人的真实印象。
