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。
And, this minimum here is what gives us the value of the inter-electrode separation, the inter-ion separation.
这个最小值就是,电极间距离的值,离子间距离的值。
Right, so here's a little piece of code that's going to print out the smallest value of three.
好,那么这一小段代码,就是会显示出,三个值中最小的来。
And that's why the Gibbs free energy is just so enormously important.
吉布斯自由能G在平衡态取得最小值,吉布斯自由能是最重要的。
They have isolated it enough that they can actually say the bare minimum about it.
他们已经将鐽,提取出来,使得他们能够得到它的最小值。
OK, so R minimum, the minimum separation occurs when the energy is at its minimum.
好的,所以R处是最小值,间距最小值出现在,当能量为最小的时候。
The minimum and the maximum is bounded.
最大最小值都是有界的。
The only place q1 appears here is here, so when I differentiate again I'm going to get -2b and sure enough that's negative, which is what I wanted to know, just to check that when I'm finding this thing, I'm finding a maximum and not a minimum.
只有这一处有q1,因此二阶导数是-2b,它肯定是个负数了,这正是我们想得到的结果,这就验证了我们刚才得出的,是最大值而不是最小值
