变量

Firstly, reviewing and commenting on foreign and domestic literature about nonrecurring gains and losses; secondly, analyzing the definition and characteristics of nonrecurring gains and losses and the reason to form nonrecurring gains and losses; following, examining the research hypothesis using descriptive statistics and correlation analysis and regression of price and return model, furthermore optimizing the price model and return model through adding year variable and district variable which was divided according the return of the extraordinary items as dummy variables in the empirical research part.

文章先对国内外关于非经常性损益的研究现状进行回顾与述评；其次对我国关于非经常性损益的界定及其形成动机进行了分析；紧接着实证部分采用描述性统计、相关分析和运用价格模型和收益模型进行回归分析，对本文提出的研究假设进行检验，并加入年度虚拟变量和按照非经常项目利润率进行划分的区间虚拟变量对价格模型和收益模型进一步优化，使线性回归方程的拟合优度R2得到显著提高，利用优化后的模型对研究假设进一步检验。

A3 rankA = d on A, and, there is a smoothly varying, nonsingular,d x d principal minor A of A.

在他们的结果中，所考虑的Hamilton系统的角变量和作用变量的数目可以不同，更为重要的，Hamilton系统可以是奇数维的。

By uniform distribution of random variables generate normal random variable algorithm.

由均匀分布的随机变量生成正态分布的随机变量的算法。

In this study, a moment method improved by the third-order normal transformation polynomial for practical slope reliability analysis with random variables having unknown distributions is discussed.

5在实际的结构或岩土工程中，有学者提出用变量正态化转换多项式解决仅知道变量前几阶统计矩的可靠性分析问题。

The data a GetChunk call returns is assigned to variable. If Size is greater than the remaining data, the GetChunk method returns only the remaining data without padding variable with empty spaces. If the field is empty, the GetChunk method returns Null.

此方法取回的数据赋值给一个变量，若Size参数大于还需要取出的数据，则该方法返回剩余数据且并不在该变量后添加空格，若字段为空，则该方法返回NULL值。

Every time you assign another number to a variable, you are creating a new object and assigning it.

每次将另外的数字赋给变量的时候，实际上创建了一个新的对象并把它赋给变量。

Of course, the order of the variables in the list can make a big difference, and if you refer to variable number 1, you must have at least two variables in the list.

当然，该命令的变量列表中可以发挥很大作用，如果你指的可变数目1 ，您必须至少有两个变量在清单中。

It also ensures consistent variable and object declarations between modules and deletes unused variables and functions.

它还能够确保变量的一致性和模块间的对象声明，并去除无用的变量和函数。

However, if you assign a value type to an Object variable, it behaves as if it holds its own data.

然而，如果将值类型指派给 Object 变量，则 Object 变量将表现得像存储自己的数据一样。

Function relation is the relation referring to one kind of one to one correspondence between two object , is to think that another variable y can take the value that one ascertains according to the function ascertaining that when a variable x takes certain value.

函数关系是指两事物之间的一种一一对应的关系，即当一个变量x取一定值时，另一个变量y可以根据确定的函数取一确定的值。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
