RUN THEOREMS OF NORMAL ORTHOGONAL DUALITY OF BINARY SEQUENCES
二进制标准正交对偶序列的游程定理

The properties of normal orthogonal duality of binary sequences are investigated by means of RCF of binary sequences. In order to prove the theorems given in this paper, the concept of pure code segment is introduced. And then, the relations between run numbers of pairs in duality, between run numbers of the code-bodyies of pairs in duality, and the type constants of pairs in duality are derived respectively.
