And I could do the same about any axis that I want.
我还可以对任意坐标轴这么做。
Specially designed actuator mounting blocks allow quick and easy actuator changes, on any axis, at any time.
特别设计的驱动器安装块驱动器可快速,容易变化,在任何轴,在任何时候。
Still, one might imagine that the particle's spin around any axis was set before anyone ever came along to prod it. That's certainly what we ordinarily assume in life.
不过,我们可能会设想,粒子沿所有轴的自旋是在测量前就确定了的,这正是一般我们在生活中所做的假设。
So any time you have two atoms bonding, the bond axis is just the axis that they're bonding along.
任何时候如果你有两个原子成键,键轴就是它们成键的方向。
So it's very important to be keeping in mind that any time you see a double bond, you have a pi bond there, so you're not going to see any rotation around the bond axis.
所以你们要记住,任何时候你们看到一个双键,这里面有π键,你们不会看到关于键轴的任何转动。
And a sigma bond forms any time you have two orbitals coming together and interacting on that internuclear axis.
当你把两个轨道合在一起,并在核间轴上有相互作用时,就形成了sigma键。
