What would happen if the coincidence of Einstein's time progress axis with one spatial dimension of these flat 2-D-spaces around us would get slowly lost?

如果爱因斯坦的时间轴与我们周围的平面二维空间的一个空间维度的恰好慢慢消失的话，会产生什么现象呢？

The D-H rule are used for solving each axis motion variable.

运用D-H法对各轴运动变量进行求解。

But in sigma orbitals, you have no nodal planes along the bond axis, so if we had a nodal plane here, we'd see an area where the wave function was equal to zero.

但在sigma轨道里，沿着轴向是没有节点平面的，如果我们有个节点，我们就会看到某个地方波函数等于0。

So what I'd like to do now is focus on a piece that emphasizes--foregrounds-- just the first axis, pitch.

那么现在我要做的是集中精力于一首乐曲,它所强调的,突出的,只是这第一维,音高

So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.

你们可以看到，如果它绕自己的轴朝这个方向转,我们就说它是自旋朝上，这个方向我们叫它自旋朝下。

Engadget had a chance to give Axis a quick spin, and we largely like what we see, even if we'd say it's not for everyone.
