Zipf发现，不同语言中，不同词语出现的频率分布符合统一的数学规律。

Zipf律（Zipf law）：将某一个单词（如the）在一篇文章中出现的次数排名记作r，该词语出现的次数记作f(r)的话，那么f(r)~r-1

以《哈姆雷特》为例，用MATLAB对其进行词频分析，并验证Zipf律。-Zipf found, different languages, different words with the frequency distribution in line with unified mathematical rule. Zipf law (Zipf law): The one word (such as the) number of occurrences in the article referred to as rank r, the number of times the word appears denoted by f (r), then f (r) ~ r-1 In " Hamlet"　for example, its word frequency analysis MATLAB, and verify the Zipf law.
