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。

After cultivated, tube plantlets weren't evidently different compared with the control (inoculated under no NaClO, free virus conditions) in main growth indexes,which showed that Oncidium' s tube plantlets could be inoculated under open conditions when film culture vessels were used.

培养后的试管苗在主要生长指标方面与对照(不添加NaClO、无菌条件下接种)相比无明显差异，表明采用树脂膜培养容器可以在有菌条件下进行文心兰试管苗的接种。

The finite-gain stability of the controller was proved under the assumption that the kernel function was local Lipschitz in this open-loop inverse control system. The sufficient condition for that Gaussian kernel function to the local Lipschitz of either variable was given. The stability of the whole system was also proved under some proper assumptions.

针对此开环逆控制系统，在核函数为局部Lipschitz的前提下，证明了控制器是有限增益稳定的，并给出Gaussian核函数对任一变量的局部Lipschitz性的充分条件，在一定合理的假设下给出了控制系统的稳定性结论。

Main Food Section 主食部分 The refrigeration system shall be designed to maintain the temperature of 4 o C to 8 o C average or below within the cabinet under all operating conditions in ambient air temperatures between 18 o C and 40 o C, with the cabinet door opened for period of 40 seconds every 30 minutes under the test condition.

冰箱的系统设计是：在检验条件下，橱柜内的冰箱正常运作，橱柜门每隔30 分钟开启40 秒，橱柜内的冰柜会保持内部平均温度低于4 o C 到8 o C，而周围环境温度为18 o C到 40 o C之间。

The errors and area limits caused by the lunar curvature were avoided in this model established under the Selenocentric Orthogonal Coordinate System, the accidental errors of exterior line elements were reduced by orbit fitting and interpolation, the polynomial orders of systematic errors in satellite orbits were decreased with their expression in the flying coordinate system moving and rotating with satellites, and the reliability of exterior orientation solution was enhanced under the condition of sparse and low accuracy control points by appending constraint of orbit and attitude parameters.

该模型通过在月心直角坐标系进行影像空中三角测量来消除月球曲率引起的误差和测图范围限制，通过轨道形状的拟合与插值来减小摄影时刻轨道位置的偶然误差，在飞行坐标系中建立轨道修正模型来减少定向参数的数目，对轨道和姿态增加约束条件来提高月面控制点数目稀少及精度低条件下外方位解算的精度与可靠性。

And presents some commonly process and attentions in applying the FEM software ANSYS to PCM analysis.2 Analyzed the PCM performances under the affection of piezoelectric and polymer"s material characteristic by FEM, and got the rule.3 Analyzed the PCM performances which affected by stickup layer"s materials characteristic and its thickness under the application of FEM.4 Based on the construction principles of 1-3 type orthotropic piezoelectric composite materials, the finite element model is designed and its orthotropy is analyzed, at the same time, the length/broad ratio to PCM orthotropy is also analyzed.

二、应用有限元法分析了压电相材料和聚合物基体相材料特性对于压电复合材料综合性能的影响规律。三、应用有限元法分析了粘贴层的材料性质和厚度尺寸对压电复合材料在实际应用中性能的影响规律。四、根据提出的正交异性压电复合材料的构造原理，设计出1-3型正交异性压电复合材料的有限元模型并分析其正交异性，同时分析了压电相材料长宽比对其正交异性的影响。

objectiveto search a simple, safe and effective method for correction of prominent mandibular angle and malar under localanesthesia.methodsaccording to the patient' s condition with prominent mandibular angle and malar, abrasive osteoplasty was performed using the special designed grinding burs with protecting sheath through intraoral incisions under local anaesthsia.resultsfrom 2004 to 2008, we have performed 35 patients with prominent mandibular angle and malar using this method.

目的：探讨一种安全、简便、有效的下颌角肥大及颧骨突出矫治术。方法：根据下颌角肥大及颧骨突出的情况，在局部浸润麻醉下，由口内入路，应用颌面骨电动手术器械行下颌角、颧骨磨削术。结果：2004～2008年，我们共实施35例该手术，所有病例治疗过程顺利，未出现骨折、大出血等并发症，经过1～36个月的随访，所有患者均对术后效果满意。

For example, witness the testimony of Albert Rhys Williams, an astute commentator on the revolution, before the Senate Overman Committee:... it is probably true that under the soviet government industrial life will perhaps be much slower in development than under the usual capitalistic system.

例如，阿尔伯特·里斯·威廉姆斯——一个对革命评论的滑头——在参议院弗曼委员会前作证说，在社会主义政府领导下，工业的发展也许会比资本主义系统更慢。

The short squeezes disappear and the player's pure strategies will be changed when the CS is added under the circumstances of which the informed trader or the insider tenders in the Treasury auction. Furthermore, under which SO is exerted after CS, any player's strategy is not changed when the market maker oversell in the WI. If the market maker buys long in the WI, and then, whether SO is exerted or not should be taken into consideration.

在信息灵通交易商或内幕交易商参与投标的国债市场里，实施"基本承销额"制度消除了他们对市商的"逼空"机会，也改变了局中人的纯策略选择；当市商在预发行交易中卖空时，行使"追加选择权"不改变局中人纯策略选择，对于市商而言，应该行使"追加选择权"当市商在预发行交易中买空时，则应谨慎考虑。
