This paper introduced the odd sieve sequence, the methods of character, estimate and triangle sum are used to study the mean value of the divisor function. An asymptotic formula of the divisor function is gave in the odd sieve sequence set to through the analytical method.

引入了奇筛数序列，主要利用特征和估计及三角和方法，研究了除数函数的均值性质，并通过解析方法给出了除数函数在奇筛数序列集合中的一个的渐近公式。

This paper introduces the definition of common quadratic Lyapunov functions and proves that the set which consists of all the common quadratic Lyapunov functions is a convex cone .

给出了共同二次Lyapunov函数的定义，并证明了全体共同二次Lyapunov函数所组成的集合是凸锥

To obtain the likelihood function indicating the uncertainty of observed information, noisy data is firstly expressed by a set of data vectors instead of a single vector, and then transferred to probability density curve defined in model space through confidence value defined in data space.

我们将数据向量的概念扩展为数据向量的集合，通过引入数据空间内的信赖度，把数据噪声转移到模型空间的概率密度函数上，即获得了反映数据本身的不确定性的似然函数。

The optimal and worst solutions of each objective function are obtained, and the solution with the earliest start-time under the fewest number is found. A series of noninferior solutions that have the earliest start-time are obtained after increasing the number of selected depots continually. The original model can be converted to search for a solution that has maximum approximation degree of positive-negative perfect point.

分别求出各个目标函数的最优解和最劣解，寻找使出救点个数为最优情况下使应急开始时间最早的解，在此基础上增加出救点的个数继续寻找，并将备选出救点集合缩小为运输时间小于上一次应急开始时间的出救点；得到一系列非劣方案后，对各目标函数按照具体情况赋予一定的权重，将原问题转化为求解使正负理想点接近度最大的非劣调度方案。

That is, formally speaking, a representation or encoding over an alphabet ∑ of a set D is a function f from D to 2^∑* that satisfies the following condition: f(e1) and f(e2) are disjoint nonempty sets 不相交的非空子集 for each pair of distinct elements e1 and e2 in D.

形式地说，对信息对象集合 D 进行基于字母表∑的物化或编码是从 D 到 2^∑*的函数 f，并且函数 f 满足以下条件：对于 D 内任一对不相同的元素 e1 和 e2，f(e1)和 f(e2)是不相交的非空子集。

The hash function is the very core of the fast lookup capabilities of the unordered sets: a hasher is just a Unary Function returning an std::size_t value for any given key.

散 列函数是无序集合的快速查找能力的核心：散列器就是一个可以对任意给定的键值返回一个 std：：size_t 值的单参函数对象。

In this method,the single index function is replaced with a variable index function set.

该方法用一个可变的指标函数集合代替了单一的指标函数，其程序流程与传统方法基本相同，只是初始化模块、算法模块以及一些预备工作有所不同。

If drop finds its element in the set, it decrements the element's reference count and the number of elements in the set.

如果drop函数在集合中发现了其参数所指向的元素，便将该元素的引用计数器和集合的计数器减一。
