This is the radial probability distribution formula for an s orbital, which is, of course, dealing with something that's spherically symmetrical.
这个s轨道的,径向概率分布公式,它对于球对称,的情形成立。
so your body develops balance, so everything develops symmetrical.
所以你的身体平衡发展,一切都是对称发展的。
So, doing those probability density dot graphs, we can get an idea of the shape of those orbitals, we know that they're spherically symmetrical.
概率密度点图上,我们可以对这些轨道的形状,有个大概了解,我们知道它们是球,对称的,我们今天不讲。
Now, if you look at the brain— If you took the brain out and held it up, it would look pretty symmetrical, but it actually is not.
如果你仔细观察大脑,如果你把大脑拿出来,放在手上,它看起去会是非常的对称,但事实并非如此
It oftentimes repeats and it can be symmetrical in that sense.
它经常重复并且感觉比较对称。
This is important because this molecule here, deoxyribose, is not the same upside down as it is - it's not symmetrical upside down and right side up, it's different because the 5' carbon's either pointed up or pointed down.
这很重要,因为对脱氧核糖来说,不都是像这样自上而下的,不是对称的自上向下或全部向上的,长链不同是由于,5'碳向上或者向下的指向不同
Half of you did above average on the Midterm; half of you did below average on the Midterm, but if I went up and asked each of you why the answers would not be symmetrical.
你们当中有一半人期中考得比平均分高;,有一半期中考得比平均分低,但如果我去问你们为什么,答案会各有不同呢。
It's also very symmetrical.
而且还显得非常对称
Well, essentially what that tells is that these s orbitals are spherically symmetrical.
实际上它告诉我们,这些s轨道,是球对称的。
