摘要
文中讨论了在软件设计中实现数据抽象化的意义以及数据抽象化在规范说明和程序中的具体方式．以堆栈为例，分析比较了在ＦＯＲＴＲＡＮ必ＴＵＲＢＯＰＡＳＣＡＬ中分别实现数据抽象化的特点，并指出数据抽象化可以是多层次的，因而适用于复杂的数据类型。
The meaning of realizing data abstraction in software design and particular pattern ofdata abstraction in standard caption was discussed in the paper. Taking stack as example,the author analyses and camparcs the features of realizing data abstraction in advcnced language FORTRAN and TURBO PASCAL, and point out that data abstraction may be multiple-levels and thussuit to complex data types.
