计算机代数语言与CASSDR系统

Computer Algebra Languages and System CASSDR

用计算机进杆代数结构的化简，是计算机代数的一个重要课题．本文给出了一个新的代数结构化简的计算机代数系统CASSDR．该系统由REDUCE和Mathematica组合而成．能从事初等函数的规范化简，并能解决许多特殊问题。

We shall deal with algebra structure simp lification by Computer, it is importantsubject of the Computer Algebra. This paper gives a new Computer Algebra system CASSDR,which studies algebra simplifcation. It is written by languages of REDUCE and Mathematica, andputs algebra sentence, designs standard simplification of element functions, studies of specialproblems. It can be a teaching software, too.
