链表是物理存储单元上非连续的、非顺序的存储结构，数据元素的逻辑顺序是通过链表的指针地址实现，有一系列结点（地址）组成，结点可动态的生成。(The chain table is a discontinuous and non sequential storage structure on the physical storage unit. The logical order of the data element is realized by the pointer address of the linked list, with a series of nodes (addresses), and the nodes can be generated dynamically.)
