二叉树的线索迂回链表

The Thread-Round-links of Binary Tree

阐述了二叉树前驱全线索化的构造策略和算法，详细地介绍了在全线索化基础上所形成的二叉权线索迂回链表，给出了后继和前驱全线索之间的转换算法，并分析了线索迂回链表的益处。

This paper expounds the principle and methods of the precursory all thread of binary tree.It also introduces in detail the thread-round-links made on the basis of all threading, and gives the algorithms of the exchange between succedent all thread and precursory all thread. Furthermore,it analyses some of the advantages of the thread-round-links.
