Based on modern program design theory , such as object - oriented , a visual slope analysis software is developed by visual basic6 . 0 , autocad , and powerstation4 . 0 介绍了面向对象等现代程序设计理论,并基于这些理论利用visualbask6 0 、 autocad二次开发、 po 。
At last , the thesis point out that making full use of modern program design theory is very necessary for engineering software to convert into commodity software 并指出将现代程序设计理论更广泛地应用于工程计算软件的研制开发是工程计算软件走向商品化的必由之路。
The apia language has fully absorbed the modern programming technique of data abstraction and function abstraction . it used many traditional mathematical symbols and fitted the mathematical custom , so the correctness of the programs which were written by apia language are very easy to prove Apla语言充分体现了功能抽象、数据抽象等现代程序设计思想,它引入了传统的数学符号和数学表达式,用apla语言书写的程序便于形式化推导和证明。
