查询词典 elasticity of demand

In this paper, test research have been performed on the two important mechanical properties indicator compressive modulus of elasticity and shear modulus. Numerical simulation has been performed on the base of results of test under the situation uniform and uneven thickness of elastomer layer, which analyze internal stress distribution of the elastomeric bearing, as follows:(1) The traditional test methods of compressive modulus of elasticity test are rather cumbersome and take up experimentalists lots of time. This paper has improved the traditional test methods of compressive modulus of elasticity test, which has collected the holding-load time together to concentrate on holding load. The tests have been performed on different types of bearings, which results show that the results of the improved test method conform to the error range regulated by the standard and can effectively save time for the experimentalists, also eliminate the accumulative error.

本文主要对板式橡胶支座的抗压弹性模量、抗剪弹性模量两个重要力学性能指标进行试验研究，并在试验结果的基础上对均匀胶层厚度和不均匀胶层厚度两种情况进行数值模拟，分析橡胶支座内部应力分布规律，具体内容如下：(1)传统抗压弹性模量试验方法比较繁琐，占用试验人员大量时间，本文对传统抗压弹性模量试验方法进行了改进，将持荷时间集中起来进行集中持荷，通过对不同类型支座进行试验，试验结果表明该改进试验方法所得结果符合标准规定误差范围，为试验人员节省了大量时间，并且还消除了传统方法中的累计误差。

The burgeoning country such as China still is it is the main motive force that urges fundamental product to rise in price, china is extremely driving to raw material demand gap of supply and demand is huge, the whole world is expanding produce will balance demand, but supply rise to always be later than rise than demand, for instance Australia plans to produce iron ore can break up one time but demand of not certain still can contented China; For instance machinery of of all kinds mine offers goods insecurity, the mechanical past of excavate gold mine orders goods need 12 months only, 3 years of ability such as need acquire finished product now.

中国等新兴国家仍是是推动基础产品价格上涨的主要动力，中国对原材料需求极其强劲供求缺口巨大，全世界都在扩大产能来平衡需求，但供给的提高总是晚于比需求上升，比如澳大利亚拟将铁矿石产能翻一番但还不一定能满足中国需求；比如各类矿山机械供货紧张，采掘金矿的机械过去订货只需12个月，现在需要等三年才能获得成品。

In the Market Equilibrium with Stocks, the necessity for existence of stocks stems from the contradictions of the continuity and discontinuity,the elasticity and inelasticity between supply and demand; stocks's role in a Market Equilibrium with Stocks formation mechanism is largely embodied by a cumulative difference of supply and demand, rather than a simple short-term supply and demand residual error.

在有库存市场均衡中，库存存在的必然性源自于供给与需求在连续性与非连续性、富于弹性与缺乏弹性之间的矛盾；库存在有库存市场均衡形成机制中的作用，更多的表现为一个累积效应下的供求差额，而不是简单的短期供求残差。

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。

This paper focuses on the node stability of eco\|industrial symbiosis system from the view of environmental economics, and set up the Node Symbiotic Economics Model on the enterprises of eco\|industrial symbiosis system by analyzing relationship on the pollutants recycle of the inter\|node interconnected enterprises. Through the observation of the supply change in the enterprise′s recycling contaminants at the node based on the mathematical solutions to the model, the effects of outside disturbances on the balance of supply and demand has been studied. If the elasticity of the product price is equal to or less than 1, the node can achieve conditional stability and if the elasticity of the product price is more than 1, the node will fluctuate periodically around a stable point, and even chaos can appear.

从环境经济学角度出发，以生态产业共生系统的节点稳定性为研究内容，通过节点间相互关联的企业之间的污染物循环利用的关系分析，建立生态产业共生系统中企业之间的节点间污染物循环利用共生经济学模型，在市场经济条件下，基于模型的数学解，通过观察节点处对污染物进行循环利用企业受市场经济影响导致的产品供给变化，研究系统外界市场经济扰动对节点污染物循环利用的供需平衡的影响。
