So both of these stories involve floating point values, but only in this case am I actually allocating memory.
所以这两个故事都涉及到浮点类型,但是只有那样我们才能真正地分配到内存。
And in contrast, in the lower left hand part of the periodic table, these 2 quantities are low, so also what we're going to see is low electronegativity.
相反地,在周期表的左下部分,这两个量的值都很小,因此我们会看到这里的电负性也很低。
We said there are seven notes in each of these two scales, twelve pitches all together within the octave.
我们说在这两个音阶中都有七个音符,一个八度包含十二个音高
This is where we don't have something that satisfies both of those categories right now.
这两个方面,我们目前都做的不是很好
We all know what "to die" means in early modern poems.
我们都知道早期现代诗歌中,“去死“这两个字是什么意思。
And say let's just print them both.
那么就让我们把这两个值都显示出来。
And then this means we'll have a total of sigma1s two electrons in our hydrogen molecule, so we can fill both of those into the sigma 1 s orbital, the bonding orbital. We don't have to put anything into the anti-bonding orbital, so that's great.
我们可以把这两个,都填入,轨道里去,成键轨道,我们不需要把什么放到反键轨道里去,这很好。
But since in drawing Lewis structures actually, in some cases you do, you can draw a dotted line that means a 1 and 1/2 bond, but most in most cases, we just draw out both resonance structures, and the way that we say it's a resonance structure is that we put it in the brackets and we put an arrow between it.
但是由于在画路易斯结构时,其实,在某些情况下是可以的,你可以画一条虚线来表示一又二分之一键,但是在多数情况下,我们就把两个结构都画出来,而我们说这是一个共振结构的表示的方法是,把它们放在括号里,并在中间放一个双箭头。
