Combinatorial model involving mixed deterministic freight volume distribution and user’s equilibrium assignment

Considering characteristics of Chinese urban mixed traffic, the author develops a combinatorial model involving the mixed deterministic traffic volume distribution and user’s equilibrium (UE) assignment on the basis of symmetrical link travel time function (or deterrence). Its uniqueness and equivalance to the Wardropian principle of UE are also proved. Finally, we give the algorithm of model.

知识产权保护行为的经济均衡分析

知识产权保护行为不仅是一个法律问题,更是一个深层次的经济问题。通过经济均衡的博弈模型集中分析知识产权利益主体的选择倾向,并从模型分析中得出若干结论,不仅较全面地解释了知识产权保护行为的内在动因问题,也为全面加强知识产权保护开辟了更有效的经济途径。     

论高校篮球教学系统自组织特性

运用文献资料和逻辑分析方法,结合自组织理论,针对篮球教学系统特性做了综合性探讨。阐述篮球教学系统自组织的开放性、远离平衡、涨落和非线性相互作用四个特性。利用这些特征在篮球教学过程中进行素质教育,营造开放的课堂气氛、激发学生对课堂的开放性、创造和利用不平衡状态,促使篮球教学系统自组织的形成。     

基于信号博弈的统一授信存货质押下银行对第三方物流的选择

选择合适的第三方物流(3PL)是统一授信模式存货质押业务顺利开展的关键环节,运用信号博弈模型,研究银行对3PL的选择问题。模型给出3PL质量越好,其预期收益越高的结论,银行以此作为判断是否接受3PL为融资业务授信对象的依据。最后给出实例比较说明结论的现实意义。

Area method analysis and thermodynamic behavior of nonmetallic micro-inclusions in casting slab of GCr15 bearing steel

The distribution and characteristics of nonmetallic micro-inclusions of GCrI5 bearing steel were explored through metallographic area method in virtue of tracer method and electronic microscope.The results show that the micro-inclusions,of which the average value is 0.032%,are mainly the compounds formed via the adsorption/aggregation of multielement deoxidized compounds and secondarily deoxidized products on tundish liquid level.The micro-inclusions of diameters from 0 to 5 μm are 92.5% in total,which basically determines the characteristics of inclusions distribution in casting slab.The inclusions of diameters more than 10 μm only account for less than 1% in total,which have little influence on steel quality.The relationship between equilibrium compositions of the first deoxidation products and molten steel compositions was also calculated based on thermodynamic theory.

现实可行的研究性教学模式的新构建——基于研究性教学必备条件的供求均衡分析

研究性教学有效实施的必备条件和现实条件之间具有很大的“缺口”,短期内弥补这种“缺口”是不现实的。文章通过对研究性教学必备条件的供求均衡分析,创设了一种现实可行的研究性教学模式。     

环渤海区域理性协调发展的战略思考

科学发展观统领下的理性协调具有时空上的丰富内涵.环渤海区域理性协调发展战略的重点主要包括非均衡发展与均衡发展的协调、局部利益与整体利益协调、城市关系协调、城乡关系协调、产业布局协调、竞争与合作协调、市场机制与调控政策协调、内源型经济与外源型经济协调八个方面.理性协调是环渤海经济区理顺关系、加快发展的关键.落实理性协调发展战略应从区域一体化角度分析合作中存在的问题,选择切实有效的途径.
