if we think about electronegativity as a periodic trend we can just draw our nice periodic table here, and let's separate it into quadrants.
如果我们来思考一下电负性的周期性规律,我们可以把我们漂亮的周期表画在这,然后把它分成四个象限。
And if the time's up and neither side has won, it's a draw.
如果时间到了,没有队赢,这就是平局。
It's a powerful force that goes behind the scene and I hope we can draw that out in this course.
它是一种潜藏在暗处的强大力量,希望通过此课可以窥得其冰山一角
The proper way to draw a vector is to draw an arrow that's got a beginning and it's got an end.
画矢量的正确方法是,画一个有起点和终点的箭头
Let's re-draw this, so it looks a little bit neater, where we have a triple bond in the middle instead, and again, we need our negative 1 charge there.
让我们重写这个,这样看起来更整洁一点,我们有一个三键在中间,同样地,我们这里需要一个负电荷。
It's going along.At a certain point-- Let's draw our amoeba splitting,right?
到了某个阶段-,我们来画它进行分裂?
So this best response actually is a pretty complicated object, and we could, if we're going to go like we did last time, we could take the time to draw this thing, but it's a bit of a mess so I won't worry about doing that right now.
可以看出最佳对策有点复杂,我们可以,像上次课所做的那样,花点时间把这些画成图表,不过这有点麻烦,现在我不会花时间去做那些
Now there many ways I can connect these two points together. The simplest way is to draw a straight line. It's called the linear interpolation. My line is not so straight, right here. You could do a different kind of line.
最简单的办法是,像这样画一条直线,这叫线性插值,不过我的这条线画得不太直,你也可以用别的办法,比如一条抛物线。
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。
So we can draw that for 1 s a, we can also draw it for 1 s b, and what I'm saying for the molecular wave function is that we have the interference between the two, and we have a constructive interference, so we end up adding these two wave functions together.
所以我们可以对1sa画出它来,我们也可以对1sb画出它来,对于分子波函数我要说的是,它们两者之间会干涉,这里我们有相长干涉,所以我们得到的是波两个波函数加起来。
So, in this class we'll be talking about energy a lot, and it's often useful to draw some sort of energy diagram to visualize the differences in energy that we're discussing.
所以,这堂课我们会讨论很多,关于能量的问题,讨论时,画能级图来使能量差别,形象化常常是很有用的。
So, one thing we said last time was when we put up a model and try and draw lessons from it, we should just take a step back and say, what's missing here?
在上一讲,当我们,从一个模型中总结结论的时候,我们应该回过头重新审视一下,看看我们是不是疏漏了什么
So when you go ahead and draw these on your problem-sets or on your exams, it's a good idea to put these dashed lines in, both for you and for people reading it to see exactly where your molecular orbitals are coming from.
所以当你在做课后题,或者考试的时候要画这些图时,最好把这些虚线放进去,既方便你自己也方便别人知道,这些分子轨道是从哪里来的。
It makes sense to draw the wave function as a circle, because we do know that 1 s orbitals are spherically symmetric.
把波函数画成一个圆是有道理的,因为我们知道1s轨道是球对称的。
