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。

All cell membranes have these channels within them, and under their resting conditions sodium is moving from outside to inside, potassium's moving from inside to outside.

所有细胞膜上都有这种通道结构,在静息状态下,钠从细胞外流向细胞内,钾从细胞内流向细胞外

So, in a sense, the tax structure was regressive.

在某种意义上,这种税制结构是退化的

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。

Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.

核酸分子杂交表示,DNA在变性状态下可以恢复活性,和与其配对的单链形成稳定的双螺旋结构,只有在完全配对时才会发生这种情况

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
