So what would I want to do? I'd like to somehow walk down each of the digits one at a time and add them up. Ah, that's a looping mechanism, right? I need to have some way of walking through them.
去取这个数的,每个数字然后把他们加起来,啊,这是个循环机制对不对?,我得找到一个遍历它们的方法,一种简单的方法可能。
I might want to add them up.
我想要把他们都收集起来。
So if we add them all up, there should be no net charge on the molecule, if the molecule is neutral.
因此如果我们把它们都加起来,这个分子上应该没有净电荷,如果这个分子是中性的话。
You add them all up algebraically, keeping track of their sign, and that's the total force.
你再对这些力做代数加法,注意符号,就求出合力了
I take the difference in the x-values, squared, the difference in the y-values, squared, add them up, take the square root of that.
好,是毕达哥拉斯定力对不对?,求x坐标的差,然后平方,求y坐标的差,然后平方,把它们加起来,开平方。
So, having other particles around that have the same energy that you could technically add up if you were adding them up like a wave, you can't do the same thing with particles, they're all separate.
所以,如果它们是波,你可以把其他的,拥有相同能量的粒子加起来,但是你不能把这些粒子加起来,因为它们是分离的。
