用面向对象技术消除递归

Eliminate Recursion with Object Orient Technic

程序设计中递归的运用可以使编程效率提高，但对时间要求及严的软件而言，递归带来的问题也很多，在网络几何画板软件开发中提出了一种运用面向对象技术消除递归的方法，使得软件代码大幅度缩短，结构清晰，软件的运行速度提高，瓶颈问题得以解决，论证了消除递归的重要性及面向对象技术在系统建模中的强大优势。

Recursion＇s application can improve program efficiency, but it occur many problem in some real time system at the same time, we proposed an Object Oriented method to eliminate recursion in net geometer sketchpad software developed, it make the code become shorten, structure clearly and save run time, the choke point be removed ingenious, it demonstrate the significant to eliminate recursion, the method also embody ОО technich＇s advantage insystem modeling.
