实数

A data type as a set can be specified in many ways:It can be explicitly listed or enumerated;it can be given as a subrange of otherwise known values;or it can be borrowed from mathematics,in which case the finiteness of the set in an actual implementation may be left vague or ignored.

作为集合的一种数据类型可以以许多方式指定：它可以明确地被列出或枚举；它可以作为排除已知值的子界被给出；或是从数学运算中借用来的，此情况是集合的穷在实数范围可以忽略。

The field survey, sampling, testing and collection of the geological and hydrogeological data were done for the description of evolutional geological structure and sedimentation and division and definition of water-bearing system and hydrogeological age and hydro-pressure system and study of the vadose field and chemical field. By establishing the rammer numerical model, the sandy mudstone thickness recovery model, water-rock interaction particle translative simulation and hydrogeochemical simulation, and using geological statistics, analogism and complex analysis method, water circulation and water exchange of each layer in each study stage have been researched, The results show the regularity of the vadose field evolution in different stages.

本项以野外调查、采样测试和搜集的地质、水文地质大量第一性资料为依据，在论述盆地的地质构造演化、沉积演化的基础上，以含水系统、水文地质期和水压系统类型的划分和定位为研究的切入点，渗流场、化学场为研究主线，通过建立压实数学模型、砂泥岩恢复厚度数学模型、水岩作用物质成分转移的实验模拟、水文地球化学模拟、地质统计法、类比法、综合分析法等方法，模拟计算了各研究层在各研究时期水循环特点和水交替强度，揭示了各研究层渗流场在地史进程中形成演化的规律性。

A convenience method which coerces the option in the specified section to a floating point number.

一个便利的方法，强制指定section的中的option为一个实数。

As for the importance of the distribution of the solutions on the Pareto front, the following measures are introduced in the dissertation: the Niching technique for keeping the genetic diversity and the real coding combining with the average crossover operator for eliminating the so-called"ending effect"of the GAs coding.

求解Pareto波阵面时，解的分布性至关重要，本文从两个角度来提高解的分布性：一是采用小生境技术解决了基因材料多样性损失问题；二是采用常规实数编码配合平均交叉算子解决了端点效应问题。

By introducing the real valued code, deteminstic crowding niching algorithm, improving the genetic algorithm, we present an evolutionary algorithm that generates Hypercube detector - Deviation Levels based Detection Algorithm and an evolutionary algorithm that generates fuzzy rule detectors - Fuzzy Rules based Anomaly Detection Algorithm.

通过引入实数编码，精确排挤小生态算法，对遗传算法进行改进，研究了基于背离等级的检测算法(Deviation Levels based Detection Algorithm，简称DLDA)，同时为了提高检测的准确性，引入了一种生成模糊检测规则的演进算法，使用模糊异常检测算法，对网络中的异常行为进行模糊检测。

In Object Pascal, Boolean expressions cannot be equated with integers or reals.

在 Object Pascal 中，布尔表达式不能等同于整数或实数的。

The city fathers have been gearing up for the event for decades but recently preparations have gone into overdrive: virtually every street has been repaved, new drains have been dug, new kerbs laid, new footpaths made and the length of the vast subway system doubled in a year.

上海的历任领导者其实数十年前就开始了城市改造，但为了世博的最新一轮准备工作实在有些过头：在一年内，上海几乎重铺了所有街道，挖了新的下水道，铺设了新的路沿，修建了新的人行道，将庞大的地铁线路延长了一倍。

Truncates a real number to an integer.

截取一个实数的整数部分

GF(25) respectively can not be factorized.

这些多项式在实数域或GF(2)上不能

Over the past few decades, people in real field on differential mid-value theorem on a lot of research.

过去的几10年里，人们在实数域上对微分中值定理进行了非常多的研究。

What are your goals and strategies for growth?

你的成长目标和策略是什么？

And unto the angel of the church in Sardis write; These things saith he that hath the seven irits of God, and the seven star I know thy works, that thou hast a name that thou livest, and art dead.

3：1 你要写信给撒狄教会的使者，说，那有神的七灵和七星的，说，我知道你的行为，按名你是活的，其实是死的。
