需求

It seems, then, that an economic theory of demand for puzzles, games and other interactive entertainment goods needs to modified in some way to allow for constraints that can raise utility and demand.

看来，那经济理论的需求拼图、互动游戏等娱乐产品的需求，以某种方式修改，以便限制可提高实用性和需求。

The third part discusses one of the core context——demand analysis,it mainly analyzes the Randomness of demand,including source and influence.Then it analyzes Poisson demand process including Characteristics,proof and the thought,feasibility and necessity of transformation to Normal Distribution and it gives the way and process of transformation——parameter estimation,Then it verifies unbias of parameter and adopts\'test of hypothesis.

第三章探讨了库存成本中的核心内容之一——需求分析，即主要针对需求的随机性进行分析，包括随机性的来源与影响，继而对需求为泊松分布进行分析，包括特点，证明及其向正态分布的转化的思想，可行性及和必要性，并给出了转化的方法及步骤——参数估计，并进行参数估计的无偏检验和假设检验。

With consideration of uncertainties in load forecasting, the triangular fuzzy number was used to express the actual load demand of users at a certain time in the future, and a set of optimal time-of-use price design models based on fuzzy demand and users' diverse response were established.

考虑负荷预测的不确定性，运用模糊三角数表示用户未来时刻的实际需求。结合分类用户不同程度的需求价格响应，构建了一套基于模糊需求和用户分类响应程度下的最优分类峰谷分时电价设计模型。

The consumer demand, the investment demand and the demand for foreign trade net export is the Troika of driving economic growth.

消费需求、投资需求和外贸净出口需求是拉动经济增长的"三驾马车"。

It may have been an unfelt want. There may have been no want at all until business action created it -- by adveryising, by salesmanship, or by inventing something new.

顾客可能根本没有觉察到这样的需求，也可能在企业家采取行动--通过广告、推销或者发明性东西，创造需求之前，需求根本不存在。

By drawing on overseas and domestic experiences, the power pricing methods of peak, flat and valley load segment and consumer demand response are analyzed and a pricing model of peak-valley TOU price considering power rate winkage between demand side and generation side and price elasticity of demand is built. The model simulation flow is also introduced in dated.

借鉴国内外先进经验，分析了峰、平、谷各时段电价的确定方法及用户需求响应，建立了一种综合考虑需求侧与发电侧电价联动和电力需求价格弹性的峰谷分时电价定价模型，并详细介绍了该模型的仿真流程。

As to the second requirement, with the development and adoption of new technology, high verisimilitude requirements are raised to avion simulation system.

随着科学技木的飞速发展，现代军机仿真训练系统面临两大需求：一是功能需求，现代军机功能的增强，使飞行仿真训练内容发生了较大变化；二是技术更新需求，新技术的发展及其在仿真系统中的应用，对军机仿真系统的逼真度提出了更高的要求。

Even if China demand is rising, the wilting economies of Europe, Japan and the U.S. more than compensate for that demand.

即便中国需求增长，欧洲、日本和美国经济的需求萎缩也足以抵消中国的需求增长。

Results:the training for nurse in ICU was absenter before working in ICU;and during in ICU,the trainings for them were not systematic and without-order;the dem...

结果ICU护士进入ICU工作前培训相对缺乏；进入ICU后培训不系统、无层次；ICU护士对综合能力的培训需求以及专业技能方面的培训需求较高；不同工作年限的ICU护士对培训需求的程度不同。

The main works of this paper include four points as follows:(1) Patent retrieval domain ontology is designed through analyzing the common concepts in searching patent information. And the international patent classification table is expressed using ontology;(2) Design users'interests model from the information actively provided by users and passively provided by system based on users'requirements and historical searching record;(3) Design and implement three patent retrieval modes: quick search, table search, and advance search to meet various users'demands. And combine ontology, user's interest model and the inputed retrieval condition when users search for patent informations. This realizes individualized retrieval which meets the demands of users;(4) When users's search term is inaccurate, the precision will drop markedly and users will receive many disrelated informations.

本文的主要工作包括以下四点：(1)通过分析专利检索的常用概念，设计了专利检索领域本体和国际专利分类表(International Patent Classification，IPC)的本体表示；(2)根据用户的需求以及历史检索记录，从用户主动提供和系统被动学习两方面着手，设计了用户兴趣模型的本体表示；(3)为满足不同层次、不同需求的用户，设计并实现了三种专利检索方式：快速检索、表格检索、高级检索，并将本体、用户兴趣模型、用户输入的检索条件三者相结合，实现满足用户需求的个性化检索；(4)通过设计将检索结果按IPC号分类，由用户自主选择需要浏览的类别来为用户提供个性化服务。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
