The structural moment of concentration on the code for its own sake cannot be avoided, and literature necessarily breeds its own formalism.
集中在代码上的结构瞬间,因为它本身的原因不可避免，文学必要地导致了它自身的形式主义。
-
It uses what in the Structural Anthropology essay he calls "mythemes" or "gross constituent units" of thought.
它用到了在《结构人类学》中,所说的思想的，“神话素“或者，“大构成单位“
-
I have the skeletal structure written up there, I've written it twice and you'll see why in a minute.
我已经把它的骨架结构画在上面了，我画了两遍，等会你就会知道为什么。
-
The loop invariant what does the loop invariant mean? It says, here is a property that is true of this structure every time through the loop.
循环不变量是什么意思？,它是一个在结构体中,每次循环都为真的属性。
-
Proteins have three dimensional structures in solution and their structure determines what they do.
在溶液中,蛋白质以三维结构存在,它的结构决定功能
-
Here, too, gets a little ugly and this is why I tend not to like this construct, at least in C, but sometimes it's necessary or it's the simplest way to achieve this goal.
这里也有点难看的，这也是为什么我,不太喜欢这个结构，至少在C语言中，但是有时它是必须的,或者它是达到目标最简单的方法。
-
And an important thing to remember when we talk about resonance hybrids is that the structure it's not 1/2 the time this structure, and 1/2 of the time this structure, it's actually some combination or some average between the two structures.
而当我们讨论共振杂化的时候,有一件重要的事情需要牢记,那就是这种结构并不是,一半时间处于这种结构的状态，而另外一半时间又变成了这种结构的状态，它实际上是两种结构在,一定程度上的组合或者平均。
-
One of the million complications of thinking about this lecture is indeed to what extent it really is a significant departure from the work of structuralism.
对这场讲座,它在何种程度上,是对结构主义的背离。
-
It is both that which organizes a structure and that which isn't really qualified to organize anything, because it's not in the structure; it's outside the structure, something that imposes itself from without like a cookie cutter on the structure, right?
它既组织结构,又不真正地具有组织任何事物的资格，因为它不在结构之中，而是在结构之外，它将自己强加于结构之上,而不是像一个饼干成形切割刀一样，是吗？
-
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。
-
I mean a blanket term, a guiding concept, a transcendental signified, something that explains the nature of the structure and something also, as Derrida says, which allows for limited free play within the structure; but at the same time the structure has this kind of boundary nature.
是一个概括性称呼，一个引领概念，一个超验所指，它解释了这个结构的内涵，正如德里达所说，它允许在结构内有限的自由游戏;,但同时这个结构也有限性。
-
So that means that we don't have to worry about things like wave functions when we're talking about Lewis structures, but because they're so simple to use and because they so often predict the electron configuration of molecules accurately, we end up using them all the time in chemistry, so it's very valuable to know how to draw them correctly and to know how to work with them.
因此这也就意味着我们在讨论路易斯结构的时候,不需要担心波函数之类的东西，但是由于路易斯结构不仅简单易用,而且用它来预测分子的电子排布,经常可以得到非常精确的结果，结果我们在化学中一直都在用它，因此知道如何正确地画出并运用,路易斯结构是非常有价值的。
-
So, what happens, this is another view of a sodium channel, so this is actually looking a little bit more at the protein structure.
那么，这里发生了什么，这是钠离子通道的另一张图片，在这种蛋白质结构中,它看起来更复杂一点。
-
So this is a case where we have resonance structures, or we call this a resonance hybrid.
因此在这种情况下我们就有了共振结构，或者我们叫它共振杂化。
-
We have two lone pairs, so if we thought about what the bonds were everywhere, 5° it would be 109 . 5, but it's bent because we're only looking at the bonds, we're not counting the Lewis structures in naming our geometry, but they do affect the angles.
我们有两个孤对，所以如果我们考虑它会成怎样的键时，应该成109。,但它是折线型，因为我们只考虑成键，在几何形状里不考虑Lewis结构，但它会影响角度。
-
DNA is a double helix, you know this, the double helix was--the structure of DNA was discovered about the time that I was born you've always lived with it.
NA是双螺旋结构,众所周知,DNA的这种双螺旋结构,是在我出生的那个年代才被发现的,它就是你生命的一部分
