摘　　要：在双代号网络图的绘制过程中,由于节点的数量较多并且节点之间的相互关系不明确,从而导致绘图过程比较困难和复杂.根据工作之间的逻辑关系,通过确定工作之间的共同完成节点,论述了增加虚工作和新增开始节点的条件,提出了一种新的绘图方法,该方法具有规律性强、易于掌握和便于后期的检查和整理等优点.The large number of nodes and their indefinite relationship result in the complicated drawing course of double code network diagram. According to the logical relationship between processes, and by means of determining the common arrowhead nodes between processes, the conditions under which void processes and new initial nodes are added, are expounded; and a new drawing method with strong regularity, easy mastery and convenience for later check and arrangement, is proposed.
