If you live in two dimensions or more, you've got to use vectors to describe most things.

So, these are some of the controversies that arise these days from cost-benefit analysis, especially those that involve placing a dollar value on everything to be added up.
以上即为近来对成本效益分析,引发的一些争论,尤其是其中那些,认为可以用金钱衡量一切的观点。
The argument that eliminates strategies 67 and above, or 68 upwards, that strategy just involves the first lesson of last time: do not choose a dominated strategy, admittedly weak here, but still.
剔除67以上或者68以上的过程,仅仅用到了上堂课所提到的第一个结论,即不要采用劣势策略,虽然这里是弱劣势,但同理
So we have two electrons in our bonding orbital, but because we use the same rules to fill up molecular orbitals as we do atomic orbitals, so the Pauli exclusion principle tells us we can't have more than two electrons per orbital, so we have to go up to our anti-bonding orbital here.
所以在成键轨道上有两个电子,但因为我们用了和原子轨道时,用的相同的规则,所以Pauli不相容原理告诉我们,一个轨道上不能有两个以上的电子,所以我们需要填充到反键轨道上去。
