均衡

Based on the important results obtained from the present research on second degree price discrimination, this dissertation makes a systemic and more practical mathematics study on the side of the manufacturer angels, including further and more deeply research on monopoly manufacturer how to actualize second price discrimination under nonlinear demand function, Nash equilibrium of second degree price discrimination under the condition of competition with different demand functions, monopoly manufacturer how to actualize second

结果表明，其纳什均衡结果存在依赖于两厂商产品的市场占有率，并且两厂商需求区间的分段数越多，其纳什均衡存在的必要条件要求他们的实力越接近；第四章针对实际情况将确定性需求条件下厂商处于完全垄断状态下的二度价格歧视理论研究推广到不确定性需求条件下的二度价格歧视理论研究，更进一步地研究了垄断厂商在线性随机需求条件下的二度价格歧视模型，用计算机模拟了此模型的可行性，分析模拟结果得出了一系列重要结论，最后给出了更具一般性的不确定需求条件下的二度价格歧视模型，并严格证明了此模型的可行性；第五章对全文进行总结。

The optimal output level is more than the equilibrium quantity.

最优产出水平高于均衡数量。最优产出水平高于均衡数量。

U The socially optimal output level is less than the market equilibrium quantity.

社会最优产量比市场均衡产量低。社会最优产量比市场均衡产量低。

We analyze especially the equilibrium rules of optimal strategy and its conditions and make a comparative static analysis to the influence of parameters to optimal thresholds after educing investment value function and optimal investment threshold.

在导出企业投资价值函数和最优投资临界值的基础上，着重分析了企业最优投资策略均衡规则及各均衡存在的条件，并就各参数对企业最优投资临界值的影响进行比较静态分析，得出了一些有意义的结论，同时给出了经济解释。

It is also necessary to improve the effective integration of quantitative and qualitative data so as to study the optimum strategy and potential impacts on the economy more precisely.

希望在今后的研究中还可以在更加细分谈判标的基础上，建立考察更多变量的动态局部均衡模型，深化应用动态一般均衡模型，对定量和定性数据进行有效融合等改进，从而可以更精确地对最优策略和潜在经济影响进行研究。

The great tour purchasing power is the drive power of promoting the region's tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, So we must arrange the regional tourism industry with a systematic method and give prominence to the central city. For its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry's arranging, developing and advancing step by step. For the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve.

中心城市居民巨大的出游力是拉动其周边旅游地发展重要的内在驱动力；由于地缘关系，区域规模经济与地域分割并存，是旅游产业运动的一个基本特征，为此必须对区域旅游经济进行系统化布局，突出中心城市的产业中心性；因其区位条件独特，中心城市在区域经济发展中居于明显的优势，与周边城乡部位存在经济发展上的梯次性，这种梯次性是区域旅游生产力布局、产业发展梯次传动，最终整体联动的经济诱导机制；根据边际效用递减规律和旅游者最大效用均衡理论，旅游消费效用最大化的均衡在无差异曲线与开支预算线的切点(即旅游目的地选择的最佳位置)上，且随着边际效用递减，目的地选择的最佳位置向远离中心城市方向移动，这就是中心城市与周边旅游地互动关系的经济学解释。

Firstly, it gives definitions of "polis" and "mart", which are two aspects of urbani

首先对构成城市化经济的两个方面"城"的概念和"市"的概念作了专门的界定，然后在分析人们对城的行为特征的基础上导出了城需求函数和城供给函数，进而推出了"城，，均衡曲线U；在分析人们对市的行为特征的基础上导出了市需求函数和市供给函数，进而推出了"市均衡曲线Y。

The political and economic equilibrium determine the economic growth and initial position of the function parameter.

模型的政治经济均衡决定函数参数的增长率以及初始条件，收入不平等程度越高，则均衡增长率越低。

Thus industry profit is positive while both consumer and operator welfare reach social optimum. Static efficiency and dynamic efficiency no longer conflicts with each other. On the contrary they could be gained simultaneously.

在这种状态下，竞争性均衡能够在不损失消费者静态福利的前提下，实现产业的持续创新，静态效率和动态效率得到了完美的统一，我们称之为"理想的均衡状态"。

During the ordinary modeling process of first order hydraulic system, some principal diagonal elements of mass matrix were zero, and the stiffness matrix was nonsymmetrical.

建立以界面信息形式表达的一阶液压均衡系统动力学方程，同时利用卷扬系统动力学方程，首次建立机械卷扬-液压均衡子系统动态耦合的数学模型。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
