摘要： 道路的定线一般在纸上进行,如能在计算机屏幕上进行,则设计者仅需研究线形 线位本身而无须考虑计算问题,方便了设计工作,这种方法叫作屏幕定线方法?该方法要求 设计既可以正向设计也可以反方向设计,既可连续进行也允许分段地非连续进行,相应的数 据存储结构如采用传统的静态结构则不能适应这种要求,提出一种动态结构线元表可较好地 解决这一问题,文章讨论了线元表的结构和实现过程?

Abstract: In a general way, horizontal alignment design is done on paper. Peo ple can get it easier if they do the work on graphic screen because in this ca se no calculation is done by a designer who only thinks of alignment design its elf. This is called direct route location method on screen, which needs a partic ular data storage method to match instead of normal static structure. A dynamic storage structure named alignment element list is developed to solve no-continua l design and double directional design (design forward or backward). This paper discusses its structure and application .
