Some programmers like to start off a linked list with a dummy node that's always empty. 有些程序员喜欢以一个总是为空的哑元节点(不表示实际数据的节点)为一个链表的开始节点。
Expatiate the necessity for adopting 3-D space modal in analysis of cable-stayed bridge calculation on construction control state, and introduce the methods of dummy member and how to use node dummy load in different modals. 同时阐述了斜拉桥施工状态结构分析中采用三维模型进行模拟分析的必要性,以及各个构件的等效模拟方法,并介绍了三维空间模型中不同施工工况下使用节点等效荷载的方法。
