Three-dimensional space is defined by x, y, and z axes.

立体空x，y，z轴描述。

It's like how in solving a Rubik's cube, order matters a lot, Or how rotating a cube about the z axis and then about the x axis gives a different final state from rotating it about the x axis, then about the z axis.

就像在解魔方时，顺序很重要， 或者先绕 z 轴旋转立方体， 然后再绕 x 轴旋转立方体， 与先绕 x 轴旋转，然后再绕 z 轴旋转立方体会产不同的最终状态。

Or rather, I should say p orbitals, because we're talking about 3 dimensional space here, so there can be one on the x axis, and one on the y axis, and one on the z axis.

或者说，我们该说p轨道，因为我们讨论的是三维空， 所以以在x轴上有一个，在y轴上有一个， 在z轴上也有一个。

What was happening was that this T cell was physically overlapping just along the line of sight, the Z axis, with a completely different cell, a neighboring dendritic cell, which was genuinely PD1 positive.

的情况是，这个T细在视线方向，即Z轴上，与另一完全不同的细——邻近的树突状细了物理重叠，而该树突状细确实为PD1阳性。

At their core, split diopters enable dynamic compositions along the Z axis of a frame rather than point an audience's attention to one subject, a split diopter creates multiple planes of action.

- 本质上， 分体式取景器能在画面的Z轴上实现动态构图， 而不是将观众的注意力集中在单一主体上；它创造出多个动作层面。

And you can think of reference frame like a Cartesian coordinates, like X, Y, and Z axes.

你以将参考系想象成笛卡尔坐标系，就像X、Y和Z轴那样。

You'll sometimes see another one, k, which represents the z axis.

有时你会看到另一个， k，代表 z 轴。

What about in three dimensions? Well, you add a 3rd axis called the Z axis, which is perpendicular to both the x and y axes.

在三维空中呢 你添加了第三个轴 叫做Z轴 它与x轴和y轴都垂直。

X and Y position, but move along the Z axis.

X 和 Y 位置，但沿 Z 轴移动。
