利用传输矩阵法推导了环与环间通过串联耦合和并联耦合两种方式形成的多环高阶谐振滤波器的传输函数公式。

Both the transfer functions of "series-coupled" and "parallel-coupled" multi-ring high order filters are derived using the transfer matrix method.

区域OD合并模块是按照一定的算法将单个调查点od矩阵合并为区域内小区间的总od，本系统主要采用两种算法：串联法和平行路法。

Regional od integration module integrates every single-point od into total regional od by special algorithm. In the system two algorithms are used: series-parallel and parallel road.
