pigeonhole principle

基本解釋

Now that we have a good grasp on the pigeonhole principle, let's see how it can be used.
現(xiàn)在我們對鴿子洞原理有了較好的理解，現(xiàn)在來是怎麼運用的。
By the pigeonhole principle, the point is either connected to at least three other points or not connected to at least three other points.
根據(jù)鴿子洞原理，這個點要麼至少與其它三個點相連，要麼至少沒有與其它三個點相連。
There are 27 words or “pigeons” that can start with one of the 26 different English letters or “pigeonholes.” By the pigeonhole principle, two of the words must start with the same letter.
假如27個單詞能以26個不同的英文字母中的一個開頭（類同於將27個”鴿子“”放入26個鴿子洞中），根據(jù)鴿子洞原理，必有2個單詞以同一字母爲(wèi)首。
