The empirical issue of income convergence has been concluded that there appears to be local convergence without global convergence, once different factors are controlled for, the evidence then points to the existence of conditional convergence.

经验研究表明，世界上只有局部趋同而没有全球范围内的趋同，一旦对不同的要素变量加以控制，将出现条件趋同。

In this article the usual method of determining the distribution density of function of one-dimensional continuous random variable——distribution function method.

本文给出了求一维连续型随机变量函数分布密度的一般方法：分布函数法，并用分布函数法对现有文献中的计算公式进行了理论探讨，对现有的定理进行修正拓展，扩大了应用范围。

A result that may be useful for part II is that if X is a continuous random variable taking positive values with cumulative distribution function F and Rn is the range of a sample of size n taken from this distribution, then

一个结果可能对第二部份有用，如果X是连续自由变量并取正值带有累积分配方程F 且Rn是取样数量范围n且Rn来自于这个分布，然后

A continuous target variable that has values in the range 0.0 to 1.0 representing probability values or proportions.

一个连续的目标变量的范围在0.0至1.0的值代表概率值或比例。

Objective To explore the reliability and applicability of computing methods based on serum creatinine for calculating endogenous creatinine clearance.

目的 探讨以血清肌酐为主要变量的公式法推算内生肌酐清除率的可靠性和适用范围。

Then cumulant invariants are used to classify bandlimited MPSK signals. The method can work with lower SNR.

并利用此基带序列的高阶累积量构造分类特征不变量，在宽信噪比范围内实现了带限MPSK信号的调制分类。

The complexity of society estate can affect the degree and scope of politics stability .Power corruption appears in the process of modernization .

社会阶层结构对政治稳定的影响历来是分析政治稳定时不可忽视的重要变量，社会层级结构的复杂性直接影响政治稳定的程度和范围。

The results indicated that dentin thickness within 0.5-1.5mm had little influence on target variable.

结果发现：牙本质自由端厚度范围在0.5-1.5mm时对目标变量的影响很小。

Because optic circuit used differentiating interferometer based on phase compress theory ,the system can not be effected by outside slow variety such as temperature. Compared with common interferometers ,the linearity range of this system was enlarged by 220 times for phase compress.

由于光路系统采用了基于相位压缩原理的微分干涉式结构，因此该系统不受外界缓变量的影响；与一般干涉仪相比该系统也因相位压缩而使工作的线性范围扩大了220 倍。

Ecause the method can track satisfactorily all types of state of a class of uncertain variable structure systems, it can extend the nonlinear state error feedback control law and auto disturbance rejection controller application field.

该方法能有效跟踪变结构非线性系统的各阶状态变量，拓宽了非线性状态误差反馈控制器和自抗扰控制器的应用范围，同时给予了稳定性证明。
