求翻译：由于引入了多种逻辑关系，前导图（PDM）的时间计算和箭线图（ADM）有一些差别。除了前导图（PDM）中不存在节点最早时间和最迟时间，在箭线图（ADM）中提及的其它时间参数也都适合前导图（PDM）（Dubois et.al.，2003）。是什么意思？

The introduction of a variety of logical relations, leading diagram (pdm) calculation of time and the arrow diagram (adm) there are some differences. In addition to leading (pdm) node does not exist in the earliest time and latest time, the other time parameters mentioned in the arrow diagram (adm)

Due to the introduction of multiple logical relations, the leading figure (PDM) the calculation of time and Arrow diagram (ADM) there are some differences. In addition to the map (PDM) node does not exist in the earliest time, and not later than the time in the Arrow diagram (ADM) mentioned in the o

Because has introduced many kinds of logical relations, the leader chart (PDM) count-down and arrow graph (ADM) have some differences.Does not have the node earliest time except leader chart (PDM) in and the latest time, mentions other time parameter in arrow graph (ADM) also all to suit leader char
