When the complementary sequences can be constructed , it is called constructible complementary sequence 特征序列对研究互补序列的特性具有重要意义。

Now there are 5 constructive methods have been found , through which all of the complementary sequences whose length is 2 ' 10s26 " can be constructed . it was proved in this paper that it can determine which equivalence class is constructible or not by the feature seque nce . based on the reseach and computer we have got all the equivalence complementary sequence class with length of not more than 40 , and found a new complementary sequences kernel with length of 20 经分析发现当序列长度n 4时，可以根据特征序列来判断互补序列等价类空间大小，这对实际应用中互补序列的选取具有一定意义；此外本文证明了互补序列等价类的唯一性，即不同的等价类不能包含相同的序列；对互补序列的各种构造方法进行分析，发现通过每种构造方法构造出的互补序列其特征序列均具有某种特性，通过论证得出可以通过特征序列来判断互补序列是否是可构造的以及可以由哪种构造方法构造，并通过特征序列证实了长度为20的互补序列的核的存在性。
