An Ellipsoidal Basis Function can make the partition of input space and make a limitary and bounded.

椭球基函数（Ellipsoidal Basis Function，EBF）使网络划分输入空间成为封闭有界的局部作用的空间，与径向基函数（Radial Basis Function，RBF）神经网络的高斯函数相比，它对空间的划分更明确。

Using variational trend of key characteristics of population, SAGS algorithm constructed flexible fitness function, cross probability function and mutative probability function.

SAGS算法利用种群关键特征的变化趋势，设计了可变的适应值函数、交叉概率函数和变异概率函数。

We can call a function that takes a nonreference, non const parameter passing either a const or non const argument.

在调用函数时，如果该函数使用非引用的非 const 形参，则既可给该函数传递 const 实参也可传递非 const 的实参。

The piecewise function is a kind of expression of specific functions, secondary school mathematics is an important function model.

分段函数是一类表达形式特殊的函数，是中学数学中一种重要函数模型。

When researching the producer's behavior,such as factor input and output efficiency,using product function or cost function,researchers frequently ignore the economic inefficiency and assume that the productor can attain the production possibility frontier.

通常采用生产函数或成本函数研究生产者行为时，一般默认生产者总是在生产可能性边界安排生产，而忽略了由于产出的经济无效率所造成的偏差，这种偏差最终会影响要素替代弹性、要素最优配置及产出效率的准确测度。本文采用面板模型的三要素成本函数循环参数估计法，通过施加规模报酬不变的假设，估算了辽宁省工业部门二类行业的相对技术无效率、配置无效率程度及要素间的相对价格扭曲，并计算了资本、劳动、能源要素间的交叉替代弹性。

A recursive function must always define a stopping condition; otherwise, the function will recurse "forever," meaning that the function will continue to call itself until the program stack is exhausted.

递归函数必须定义一个终止条件；否则，函数就会&永远&递归下去，这意味着函数会一直调用自身直到程序栈耗尽。

The signal transfer function is considered as the most basic and important parameter to evaluate the characteristics of the infrared thermal imaging system,and is the linear portion of the responsivity function.

信号传递函数是评价红外热像仪性能的最基本且最关键的技术指标之一，它是响应度函数的线性部分，从响应度函数测试曲线中可得到待测系统增益、线性度、动态范围和饱和度的信息。

This paper first discusses the nature of the kernel function,and then based on Riemannian geometry dependent on the data structure and method,an improved modifying kernel function is proposed,the kernel function is a simple and less calculation method,which conformal factor and support vector irrelevant,compared with previous studies overcomes the impact of support vector's number and distribution.

首先讨论核函数的本质，并且基于黎曼几何结构和数据依赖的方法，提出了一种改进的修正核函数，改进后的核函数形式简单，计算量较低，其中保形因子与支持向量无关，较之于以前的研究克服了支持向量的数目和分布的影响。

The paper studied the multiobjective semidefinite programming with a semidefinite constraint of a matrix function and a multiobjective function.

主要研究含矩阵函数半定约束和向量函数等式约束以及多个目标函数的多目标半定规划的对偶和鞍点问题。

This paper discusses some application cases of the error propagation law by the examples of trigonometrical survey, and presents that not only sum function and numeral multipling function in which there is only one independent observed value but also more complex functions which are equal in mathematics are not opposite in the process of error propagation according to the error propagation law.

1引言本文以三角测量为例，对误差传播定律一些应用问题进行了讨论，指出当只有一个独立的观测值时，和函数与倍数函数运用误差传播定律不会出现悖论；如果在测量工作中有多余的直接观测值，就需用平差后的间接观测值按协方差传播律来计算，这样数学中相等的函数关系才能得到同样的函
