He could divide all of that by the absolute value of the charge of the positive particle, all over the mass of the positive particle.
他可以把这整个,除以正电粒子的,电荷绝对值除以,正电粒子的质量。
And you probably recognize some of them in there, cors right, absolute value, add, comp, cors, cors well we didn't do cors, we did a bunch of other things.
对,绝对值,假发,比较,当然我们还没学,我们学过其他的一些东西了。
The absolute number that you assign to it is something that's arbitrary. You have to set what the zero is. And so there's a well-understood convention for what the zero is.
你指定给它的绝对值是有任意性的,你需要设定零点的位置,因此有一个经过充分研究的,关于设定零点的约定。
So, we can also get into a case where we have similar values in terms of absolute values of formal charge between two different molecules we're deciding between in their Lewis structures.
我们还可能遇到另外一种情况,那就是在我们需要进行,选择的两种路易斯结构中,形式电荷具有相似的绝对值。
Let me write it as g minus the absolute value of a.
我就写成 g 减去 a 的绝对值
So this negative number has a bigger magnitude than this negative number.
所以这个负数的绝对值,比这个负数大。
But we could, for example, look at a case where we have several different structures that look pretty good, and the one we want to determine as being the lowest energy structure is the one in which the absolute values of the formal charges are going to be lower, so essentially that they have less charge separation.
但是我们可能,比如,遇到一种情况,有好几个候选的路易斯结构看起来都挺好的,这时候我们就需要,通过比较哪个形式电荷的绝对值更低,来决定哪个结构的能量更低,本质上这个结构中分开的电荷更少。
In this case, I probably want to make sure I use absolute value of x before I carry it on. Yes ma'am.
在这个例子中,我可能想确定,在进行测试前我用的是x的绝对值,什么问题?
