假如我错过了一个有32支球队参加的足球赛,赛后我问一 个知道比赛结果的观众“哪支球队是冠军”?他不愿意直 接告诉我,而让我猜,每猜一次,他要收一元钱才肯告诉 我是否猜对,那我需要付多少钱才能知道谁是冠军呢?
我可以把球队编号,从1到32,然后问“冠军球队在1-16 号中吗?”,假如他告诉我猜对了,我就接着问“冠军在 1-8号中吗?”,假如他说猜错了,那我就知道冠军在9-16 号中。这样只要5次,我就能知道哪支球队是冠军

M = VI- VIII族元素
金属原子或离子一般为 VI 到 VIII 族间的元素,金属处于低价态,通常被电子 受体类配体如 CO 稳定化。在这类络合物中 sp2 碳中心与其配体之间的距离比相应的 单键短,因此可能存在着三个共振结构
