So what we see is that structure a is the most stable because we have the least separation of charge in the case of structure a.
因此我们看到结构,A,应该是最稳定的,因为这种情况下,分开的电荷最少。
Legacy software commonly suffers from poor cohesion (bad separation of concerns) and the "problem of control", in which objects are in charge of creating their own dependencies.
遗留软件通常受制于糟糕的强依赖(关注的拙劣分离)以及“控制的问题”,即对象负责创建自己的依赖。
It is an integral part of the electron transport chain that catalyses primary charge separation.
这是一对电子传递链的电荷分离催化的主要组成部分。
So what we see is that structure a is the most stable because we have the least separation of charge in the case of structure a.
因此我们看到结构,A,应该是最稳定的,因为这种情况下,分开的电荷最少。
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似,因为在画路易斯结构的时候,你总需要一个起点,但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷,比如有一个正二,一个负二,还有一个负一1,在原子的各个地方,这应该就是在告诉你,或许还有一个更好的路易斯结构。
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。
