摘　　要：独特码的原始码型序列是由两种事件组成的字符串形式,考虑到直接从原始码型序列本身来寻找信息的困难性,故采用基于图形表示的独特码码型序列比较方法。该方法通过将码型序列转换为图形表示,然后将图形映射为矩阵,再通过比较矩阵不变量的方式来比较独特码码型序列的相似性。根据独特码的特性提出的基于图形表示的比较方法是一种新手段和新方法,能够更直观地观察独特码码型序列之间存在的差异以及发现隐含的信息,更有效地对独特码码对进行序列相似性分析。The original code sequence of unique signals is a string form composed of two kinds of events.Considering the diffi⁃culty of finding information directly from the original code sequence itself,the comparison method of unique signal sequences based on graphic representation is adopted.This method compares the similarity of unique signal sequence by transforming code sequence into graphic representation,mapping the graph to matrix and comparing matrix invariants.According to the characteristics of unique signals,the comparison method based on graphic representation is a new method,which can more intuitively observe the difference between unique signal code type sequences and find the hidden information,and more effectively analyze the sequence similarity of unique signal pairs.
