本文所选的符号信源是从键盘上的94个字符中随机抽取，产生50000个随机符号数，包括了大小写字母和一些基本的字符。这些随机数为了方便起见我在网上随机摘抄了几篇英语文摘作为50000个随机产生的符号数以此来统计这些字符出现的概率，统计出概率，信源熵也自然求出，但本文只统计出符号信源出现的概率。-In this paper, the selected source symbol from the keyboard of 94 characters in a random sample, resulting in 50,000 the number of random symbols, including the upper and lower case letters and some basic characters. These random numbers for the sake of convenience I excerpt a few random online English abstracts as 50,000 the number of randomly generated symbols as a means of statistical probability of these characters, the statistics of probability, a natural source of entropy is also obtained, but this article only statistics source symbol probability.
