我认为这是绝对需要的。
至于编码的技巧就是让每个模块具有它绝对需要的功能并且到此为止。
For coding, the trick is to let each module have the functionality it absolutely needs and stop there.
克莱恩指出这一积极的发展趋势,他说:“这种进步是绝对需要的。”
Noting this positive development, Klein said, "this progress is sorely needed."
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。
The lowest possible temperature in the Celsius scale is minus 273.15 degrees Celsius. So that begs the notion of re-referencing our reference point, of changing our reference points.
在摄氏温标中,绝对零度是-273。15摄氏度5,这样,我们需要重新定义参考点,将零度的参考点取在绝对零度处,而不是0摄氏度处。
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。
