一元运算

在数学系统中的一元运算里一个元素往往只产生一个单一的结果。

In a unary operation in a mathematical system one element is used to yield a single result .

然后进一步采用一元运算将信息位数增到最大。

Then by adapting the one-element-operator , the number of information bit increases further to maximum .

基于上述考虑，在本文中，我们提出了由区间的无限序列组成的区域的概念，定义了区域的一些一元运算和二元关系。

In respect that , the concept of region which is made up of infinite interval sequence is introduced .

使关系元组在由外存至主机的流动过程中就并行完成筛选、投影关系代数的一元运算。

When relational tuples are flowing from mass storage to host via this filter , the unary operations of relational algebra for them such as projection and selection are completed parallelly .

NTL库是开放源代码的自由软件库，它提供了大整数的运算，一元多项式的运算等，遗憾的是，它只提供了一元多项式因式分解，没有提供多元多项式因式分解。

NTL is a GNU library and the source code is open for us . It can operate large integer and univariate polynomials , unlucky , it only has the univariate polynomial factorization , no multivariate polynomial factorization .
