Sometimes it's also called the internuclear axis.
有时候它也叫核间轴。
A triple bond, again is going to have one sigma bond on the internuclear axis.
一个三键，同样的也有沿着核间轴sigma键。
Any time two orbitals come straight on together in that internuclear axis, you're going to have a sigma bond.
任何时候两个轨道，在核间轴上直接到一起，你就能得到sigma键。
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。
And we can actually better visualize this if we plot how that energy changes as a function of internuclear distance.
而我们就能更清楚地看到这些，如果我们画出，能量随核间距的变化曲线。
The internuclear distances and force constants of the elementary molecules as well as of the nitrides and halides, exhibit a similar behavior.
单质分子和氮化物与卤化物，其核间距与力常数都表现有相似的行为。
Internuclear ophthalmoplegia was unilateral in 136 of the infarct cases (87%), 38 of those with multiple sclerosis (27%), and 48 of the unusual cases (42%).
并且，单侧的侧的核间性眼肌麻痹为梗塞患者中的136名(87%)、多发性硬化中的38名(27%)，48名非常见原因患者(42%)。
