字母频率

在将数组按字母频率排序后，创建字母图并使用它们尝试将文本解码。

Once we have the arrays sorted by letter frequency , create a map of letters and use them to try decoding the text .

统计出来之后，用字母的频率分布与德语的普遍分布进行比较，普遍分布情况可以制成模板。

After a given total count had been achieved , the frequency distribution between the letters could be compared with the one appropriate to the language , which could have been set up on some kind of template .

但是，这样一个简单的、单字母的替换规则，只要通过观察字母的频率、相同字母的规律等等，就可以很容易地破解。在普林斯顿的寻宝游戏中，艾伦他们通过设计一些XERXES之类的古怪词语，来增加破解的难度，

Such a simple , or ' mono-alphabetic ' cipher could easily be solved by looking at letter frequencies , common words , and so forth , and in fact the only point of puzzle-page problems was that the setter would include peculiar words like XERXES to make this difficult .

我喜欢f这个字母，但是书上用希腊字母υ来表示频率。

I prefer the letter f , but our book uses the Greek letter nu .
