These variables were entered into the regressions as control variables because of their influence on employee compensation.

In an algebra proposed by George Boole about 1850, the variables are permitted to have only two values true or false , usually written as 1 and 0, and the algebraic operations on the variables are limited to those defined as AND, OR, NOT.

George Boole 在1850年提出的代数学中，变量值只有两种：真和假，通常记为1和0，代数运算也仅局限于与、或、非。

In general, when a given predicate P, x1, x2,..., xn is the object variables, P (x1, x2,..., xn) is not a proposition, because he can not determine the true value, in order to make it a proposition , use the constant instead of nn-object object variables ...

一般来说，当谓词 P给定， x1，x2，…，xn是客体变元，P(x1，x2，…，xn)不是一个命题，因为他的真值无法确定，要想使它成为命题，要用n个客体常项代替n个客体变元。。。。

Structural topology optimization is formulated in terms of the nodal variables on the level set function , which is converted to 0-1 variables by Heaviside function regularized by the sigmoid function.

利用有限元离散后的水平集函数的节点值作为拓扑设计变量来求解连续体拓扑优化问题。

A line of best fit can be drawn in order to study the correlation between the variables.

一个最适合的线路，可以得出，以研究变量之间的相关性。

The samples actually observed. In contrast Bayesian methods view the parameters as random variables having some known a priori distribution.

与此不同的是，贝叶斯估计则把待估计的参数看成是符合某种先验概率分布的随机变量。

As the center or the Algebra subalgebra of a algebra plays an important role in reducing the number of state variables, the cartan subalgebra is a maximum Abelian subalgebra of an algebra, so it can be a powerful tool for the structure simplification of control systems.

由于代数的中心，或交换子代数在系统的变量降低方面具有重要作用，而Cartan子代数是李代数的极大交换子代数，因而它能成为简化系统结构的有力工具，第二部分利用向量场的积分曲线所定义的映射，构造出一个S—坐标，在该坐标下任一向量场都有一个标准的表示方法，一种无穷级数表示方法。

But according this method, if variables are very many, it will be difficult to solve the equation using the current method. In this paper, it provides a simple method by discussing the structure of solution based on the theory of free abelian group.

本文利用矩阵和自由阿贝尔群的理论，对一次不定方程的解的结构进行了讨论，并利用其结论给出了一种简单解法。

But they assume the abscissa, the ordinate of the MS and the distance between the MS and the severing BS are three independent variables neglecting their correlation.

其主要缺点是把移动台的横坐标、纵坐标与移动台到服务基站之间的距离作为3个相互独立的变量，忽略了3者之间的相关性。

Through comparing with the results by simulation to study the effects of theprojectile"s final velocity, the angle of rotation and the ballistic trajectory"s migration withdifferent projectile"s rotating speeds, different target"s moving speeds and differentpenetration angles.
