摘要
各种专业领域的科学工程软件,在应用数值方法解决各自的计算问题时,常常需要输入加工大量原始数据.设计这些数据的描述语言并编出各自的加工程序成了科学工程软件前处理的主要工作.本文综合了数据型问题描述的几种带共性的描述方式,提出了一种面向科学工程计算问题的描述语言模式.它将专业词汇标定与语法定义相脱离。
In this paper, a kind of Problem-Oriented language designed for scientific engineeringsoftwares is introduced. It synthesizes some common approaches to describe problems charac-terized by their data. The speciality vocabulary is separated from its grammar definition foruniversality. Its interpreter is generated by YACC. Based on this, the POL of any applica-tion field can be designed and the corresponding interpreter can be generated most conveni-ently. Because of its uniform user-interface, the lenguage can lead to a better developing en-vironment for scientific engineering softwares.
