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(duì)鴿子洞原理有了較好的理解，現(xiàn)在來(lái)是怎麼運(yùn)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(gè)點(diǎn)要麼至少與其它三個(gè)點(diǎn)相連，要麼至少?zèng)]有與其它三個(gè)點(diǎn)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(gè)單詞能以26個(gè)不同的英文字母中的一個(gè)開頭（類同於將27個(gè)”鴿子“”放入26個(gè)鴿子洞中），根據(jù)鴿子洞原理，必有2個(gè)單詞以同一字母爲(wèi)首。
