The above relation shows that a selection algorithm that selects individuals in proportion to their fitness actually allocates exponentially increasing trials to above- average schemata. In GAs, this process of allocating exponentially increasing trials to above-average schemata is carried out for a large number of schemata at the same time and is referred to as implicit parallelism Dozier et al.

However, if the amplitude excessed 90%, the mounts of larger bubble increase as the increasing time.

另外，选择惰性气体SF6作为微泡内气体，设计了基于两种非离子表面活性剂（Span 60和Tween 80）的包膜超声造影微泡的膜材料组成，使用声振法制备得到表面活性剂包膜的超声造影微泡；对制备过程中的声振条件进行优化，结果表明总体上振幅越大，处理时间越长，声振后溶液的总体积增加得越多，即产生的微泡量越大，并且平均粒径越小，但当声振幅度增大到90%时，随着声振时间的延长，主要增加的是大微泡的量，有效微泡的量无明显增加，因此最佳的声振条件选择为振幅90%，声振时间60s。

With the historical research into the Communist Party of China leading Chinese people to carry on the industrializes construction after the foundation of our country, from the history angle. This text expect to analyze and research the theories basis and history foundation of the choice of china"s industrialization road at different history period, and on the base of this foundation, summary the characteristics of China"s industrialization road seriously.

本文通过对建国后中国共产党领导中国人民进行工业化建设的历史考察，以期从历史的角度出发，分析研究在不同的历史时期，中国工业化道路选择的理论依据和历史基础，并在此基础上认真总结中国工业化道路的特点本文由前言、结束语和三个主体部分构成：前言简要陈述了论文的研究背景、相关研究进展和研究方法；第一部分，客观分析在计划经济条件下，中国选择优先发展重工业的工业化道路的历史必然性。

2In order to reduce the randomness of choosing initial centers, this paper puts forward an algorithm of initialing centers called BD which is based on density. According to the whole construction of dataset, the dataset would be partitioned by density first and then choosing initial centers on the basis of some strategies. It will make choosing work more reasonable.

提出了一种初始点选取的算法，即基于密度划分的BD算法，目的是为了减低初始点选取的随机性，它是从数据集的整体结构出发，先通过对数据集进行密度划分，在此基础上按照某种策略选择初始点，使初始点的选择更加合理。

In view of these shortcomings, this frequency meter has made the radical innovation in the design, its merit is: Uses the core component is the advanced monolithic special-purpose frequency measurement component -- monolithic frequency meter, the integration rate is high, the volume is small, consumes the electricity province, function, has realized the frequency meter high integration and the microminiaturization; So long as the monolithic frequency meter adds on the crystal oscillator, the measuring range choice, the frequency demonstrated and so on the very few components then constitute DC to the 10MHz miniature basic frequency measurement electric circuit; But the biggest merit was this frequency meter has realized monolithic frequency meter, frequency sampling electric circuit and the monolithic microcomputer three between hardware and the software connection completely, caused the frequency measurement measuring range the choice, the frequency data survey, the sampling as well as the code frontier transformation and the data dump possible monolithic microcomputer software programming automatically to carry on, thus has realized the frequency measurement and the sampling work intellectualizes completely, causes this system already to be possible to constitute a miniature intelligence to measure rate the instrument core electric circuit independently, also might take in the large-scale automatic control or a test system intelligent subsystem.

针对这些缺点，本频率计在设计上作了根本的革新，其优点是：所用核心器件是先进的单片专用测频器件——单片频率计，集成度高，体积小，耗电省，功能强，实现了频率计的高度集成化和微型化；单片频率计只要加上晶振、量程选择、频率显示等很少量的器件即可构成一个DC至10MHz的微型基本测频电路；而最大的优点则是本频率计完全实现了单片频率计、频率采样与单片微机三者之间的硬件与软件接口，使得测频量程的选择、频率数据的测量、采样以及编码的边境转换和数据的转储均可能过单片微机的软件编程自动进行，从而实现了测频与采样工作的完全智能化，使得本系统既可独立构成一个微型智能测率仪器的核心电路，也可作为大型自动控制或测试系统中的一个智能子系统。

And the effect of loss aversion in quality looms larger than that in price, and the effects of loss aversion in product and service choice are also different: the former is more salient.

在第三章中，本研究通过建立消费者选择模型，并采用实验的方法收集相关数据对模型参数进行推断，验证了消费者选择的参考效应。

With regard to the government interference question, economics often takes it as an economic variable quantity. As in economics, adopting different premising hypothesis will lead to different conclusions, which means that economics only explains various possible choices of government interference. Choice of certain government interference mode only reflects the economist's value tendency to a great extent.

对于政府干预问题，经济学往往把其作为一个经济变量来看待，由于在经济学中，采用不同的前提性假设会导致不同的结论，这意味着，经济学只是对政府干预的诸多可能的选择进行解释，某种政府干预模式的选择很大程度上仅仅反映经济学家本人的价值观倾向。

When complete a deep and ultra-deep well casing program, especially a gas well, strength design, thread sealing design and anticorrosion design are needed to introduce. Meanwhile, many factors including external loadings, casing strength models selection, plastic rock creep stress, intermediate casing wear, temperature effect, thread air tight ability are necessarily considered.
