The design ideas for the digital delay line are presented, which has long total delay time, short step delay and flexible controlling method. 阐述了一种总延迟时间长、延迟步长时间短,且延迟时间控制灵活的数字延迟线设计思路和方法,同时对设计中的关键问题进行了理论阐述和推导。
The total urban traffic demand is distributed on the all general traffic roads, adopting every path distributing method in traffic distributing step of four steps forecast method. 然后根据四阶段预测法里交通量的分配步骤中多路径分配法,将城市总交通需求分配到城市常规交通路网上,得到城市总交通需求在各常规交通路段上的分配。
