So in all of these examples, the preposition " at" is used to talk about specific places or points in space.

那么在所有这些例子里，介词 " at" 被用于谈论空间里特殊的地点或标志。

The physics student perspective is that vectors are arrows pointing in space.

物理学生的观点是向量是指向空间的箭头。

They are points in space where the gravity is so strong, nothing can escape their pull.

它们是太空中引力非常强大的点，没有任何东西可以逃脱它们的引力。

An event is something that happens at a particular point in space and at a particular time.

事件是在特定空间和特定时间发生的事情。

His half-open eyes stared at a fixed point in space, bloodshot spheres that twitched

他半睁着的眼睛盯着空间中的一个固定点，布满血丝的球体在抽搐。

And this isn't just for writing addresses; this is for referring to any point in space on the Planet.

这不仅仅是为了写地址；这是指地球上空间中的任何一点。

The effect for various transformations moving around all of the points in space is, you've got to admit, beautiful.

在空间中移动所有点的各种变换的效果 你必须承认 很漂亮。

At every point in space we’re getting a new profile of light rays. We’re getting new perspectives on the scene.

在太空中的每一点，我们都会获得新的光线轮廓。我们对现场有了新的看法。

They're produced when a star collapses in on itself, creating a point in space where gravity is so strong, even light can't escape from it.

它们是在恒星坍缩的时候产生的坍缩使空间形成一个引力，非常强烈的点以至于光都无法逃脱。

Like I... Just even blocking a kick, trying to block over and over and find the right point in space to put your hand.

就像我一样… … 甚至只是挡住一脚踢，试图一遍又一遍地挡住并找到合适的空间点来把手放。

A singularity may be indefinitely dense, meaning all its mass is concentrated into a single point in space, with no surface or volume, or something completely different.

奇点的密度可能无限大，也就是说它所有的质量都集中在空间的一个点上，没有表面积和体积，或者是完全不同的形式。

However, grouping photoreceptors loses details in the image, as fine details require a fine grid of photoreceptors, each detecting photons from one small point in space.

然而， 对感光器进行分组会丢失图像中的细节，因为精细的细节需要感光器的精细网格，每个感光器都从空间中的一个小点检测光子。

The reason triangles are used, and not squares, or polygons, or some other more complex shape is simplicity: three points in space unambiguously define a plane.

使用三角形而不是正方形、多边形或其他更复杂的形状的原因很简单：空间中的三个点明确定义了一个平面。

So an orbital-- let's say that's the nucleus it would describe, if you took any point in space around the nucleus, the probability of finding the electron.

所以一个轨道——假设这是它描述的原子核，如果你在原子核周围的空间中取任何一点，找到电子的概率。

The strength of the wave at one certain point in space determines how likely it is that you will find an electron there at any given time if you measure.

如果您进行测量，波在空间中某一特定点的强度决定了您在任何给定时间在那里找到电子的可能性。

And we can calculate the energy density associated with an electric field – at any point in space – by dividing the potential energy by the volume between the plates.

我们可以计算与电场相关的能量密度 任何点或真空，通过将势能除以两个板之间的体积。

It is always assumed that there is something indestructible which is capable of motion in space; what is indestructible is always very small, but does not always occupy a mere point in space.

人们总是假设有某种坚不可摧的东西能够在空间中运动；坚不可摧的东西总是很小，但并不总是占据空间中的一个点。
