In this paper,the symbol calculation touching upon some questions,developing and using conditions of the symbol mathematics software are discus-sed,probing into the famed symbol mathematics software(muMATH).

众所周知,科学计算包括数值计算和符号计算两种计算。计算机能够对数值进行一系列运算是人所共知的事,但计算机也能够对含未知量的式子直接进行推导、演算则并不是人人皆知的事。数值计算和符号计算本来应该是并存的两种计算,是计算的平行的两个部分,决不能厚此薄彼,因此这两种计算都是一样重要的。利用计算机对一个函数进行求导、积分,这早已成为事实。本文将着重讨论符号计算所涉及的一些问题,符号数学软件的发展情况和使用情况,以及对较有名气的符号数学软件 muMATH 的探讨。

Aim To quantitatively study three characteristics of the Weibull distribution. Methods Theoritical analysis of the three characteristics of parameters of the Weibull distribution was done and mathematics software was used to make some chart analysis. Results 17 equations and 7 figures were made. Conclusion Under the standard form, the class of the Weibull probable density founction(pdf) curves appear double peak shape. Under the standard form, the maximum value point curve of the Weibull pdf takes line t =0 and t=1 as asymptotes. When β = 3 30-3 40, the Weibull distribution is the most similar to the normal distribution.
