Crash Course Physics 速成课物理

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。

Linear algebra

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.

在三维空间中呢 你添加了第三个轴 叫做Z轴 它与x轴和y轴都垂直。

化学 Crash Course

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.

或者更确切地说， 我应该说 p 轨道，因为我们在这里谈论的是 3 维空间， 所以可以有一个在 x 轴上，一个在 y 轴上， 一个在 z 轴上。

笛卡儿坐标系 Cartesian coordinate system

（重定向自Z axis）
在这篇文章内，矢量与标量分别用粗体与斜体显示。例如，位置矢量通常用\mathbf{r}\,\!表示；而其大小则用r\,\!来表示。

在数学里，笛卡儿坐标系（Cartesian coordinate system），也称直角坐标系，是一种正交坐标系。参阅图1，二维的直角坐标系是由两条相互垂直、0点重合的数轴构成的。在平面内，任何一点的坐标是根据数轴上对应的点的座标设置的。在平面内，任何一点与坐标的对应关系，类似于数轴上点与坐标的对应关系。

采用直角坐标，几何形状可以用代数公式明确的表达出来。几何形状的每一个点的直角坐标必须遵守这代数公式。例如：直线可以标准式ax+by+c=0、斜截式y=mx+k等式子来表示;一个圆，半径为r，圆心位于(a,b)。圆圈可以用以(x-a)^2+(y-b)^2=r^2表示。

Cartesian coordinate system 笛卡儿坐标系

（重定向自Z axis）
Illustration of a Cartesian coordinate plane. Four points are marked and labeled with their coordinates: (2,3) in green, (−3,1) in red, (−1.5,−2.5) in blue, and the origin (0,0) in purple.
Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius.
A three dimensional Cartesian coordinate system, with origin O and axis lines X, Y and Z, oriented as shown by the arrows. The tick marks on the axes are one length unit apart. The black dot shows the point with coordinates x = 2, y = 3, and z = 4, or (2,3,4).
The coordinate surfaces of the Cartesian coordinates (x, y, z). The z-axis is vertical and the x-axis is highlighted in green. Thus, the red plane shows the points with x = 1, the blue plane shows the points with z = 1, and the yellow plane shows the points with y = −1. The three surfaces intersect at the point P (shown as a black sphere) with the Cartesian coordinates (1, −1, 1).

A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0, 0). The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin.
