# 笔名汉字频率分析


数据来自《书法练习轨迹--明月几时有 (opens new window)》中关于本人笔名的记录。


# 1、笔名分析

  • 当前笔名：无为徐生
  • 注册多少app就有多少账号，每个账号都会有昵称或者用户名，因为昵称可以修改，故而昵称的数量会远远大于账号数量（像QQ、微信用了几年甚至十几年，昵称不知道变了多少次）。简单说明一下，手机上安装了多少app，大家的昵称数量就会大于这些app的数量。所有人皆是如此，所以现代人的昵称都很多很多。
  • 笔名就像姓名一样，同名现象相当普遍，因此很难准确找到目标对象。相比而言，邮箱 1021151991@qq.com 具有唯一性，是有效的也是本人常用的。
  • 本文档是根据《书法练习轨迹--明月几时有》中本人所记录的历年所用的上百个笔名、昵称、账号使用java分析这些笔名的分类数量及使用频率，做比较简单的数据统计和笔名分析。
