摘要: 参照REDUCE系统,在PC微机上,建立了一个用于非数值处理的符号解析系统和语言。本系统具有较为完备的系统控制功能与错误处理能力,允许作业嵌套,并可随时打断作业的运行。窗口和功能键的设置为使用者提供了很大的方便。最后,给出两个非数值用例。

Abstract: By referring to REDUCE system, a new system and language of non-numerical manipulation for symbolic analysis has been built on PC micro-computer. The sysmbolic analysis system is a mathematical expert system, which makes the use of the principles and methods of artificial intelligence to solve the algebra, calculus and other calculating problems. In addition to being a system for calculating manipulation,it is also a language for the statement of problems. With a set of simple syntax, users can write program in its own source language.The system can operate both in interactive manner or in porgram manner. The results are given in two-dimensional analysis form or FORTRAN source program form which may be used in numerical calculation later. The system has complete systematic control functions and error-handling capability, allowing job-embeding. The job may be interrupted if necessary. Windows and function-keys provide great convenience to users. Finally two non-numerical examples of the system are presented.
