So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错,把这个从,最大值到最小值的距离,叫做幅值,但实际上,只有它的一半,只是它和平均值的差距。

OK. Now. Think for a second about computing the average age of the faculty.
好,想想怎么,计算全体教员的平均年龄吧。
The electrons are not equally shared and the carbon hogs the electrons a little bit more than the hydrogen, so the carbon is electron-rich and the hydrogen is just a little bit electron-deficient.
电子不是平均共享的,碳原子比氢原子吸引电子,更强烈一点点,所以碳原子是富电子,而氢原子是缺电子。
And when we're talking about the amplitude of the wave, we're talking about the deviation from that average level. So, if we define the average level as zero, you can have either a positive amplitude or a negative amplitude.
当我们讨论一个波的振幅时,我们说的是偏离平均位置的量,如果我们把平均位置,定义为零的话,那幅值不是,正的就是负的,有时候人们在。
For a couple of reasons. In some ways, this would be nicer, do expected cases, it's going to tell you on average how much you expect to take, but it tends to be hard to compute, because to compute that, you have to know a distribution on input.
关注最快的情况,在某种意义上来说,因为一些原因这样想挺不错的,当我们处理一个给定的问题,计算平均时间的时候,是很难计算的,因为你并不知道输入的分布情况,这些输入会是怎么样的呢?
