The dominance rules can be utilized to develop a relationship matrix which allows the branching algorithm to eliminate a high percentage of nonfeasible solutions.

利用优势法则可以系矩阵，此矩阵可以用来消去极大量的效解。

It shows that this kind of device can be tuned hundreds of nanometers.It can demultiplex any channel in all-wave fiber WDM in the future.

分析表明，它的调谐量可以达到数，有望在将来的全波光纤WDM中对所有信道进行解复用。
