基于进化博弈的供应链市场进入博弈分析赵晗萍，冯允成，蒋家东(北京航空航天大学经济管理学院，北京 100083)摘要：为分析供应链的结构，在借鉴古诺竞争模型与报童问题模型的基础上，建立了市场无法出清条件下供应链的市场进入博弈模型，从理论上分析并求解了两级供应链的可行结构和均衡结构。

Early diagenesis has broad and bright prospects not only in theory but also in application, and three future trends are predicted. First, the area of early diagenesis study will be enlarged widely to lake, delta, soil. Then, the stable or nonstable one-dimensional, two-dimensional or three-dimensional multi-layer early diagenesis models will be established, and the methods and theoretical achievements of early diagenesis will be widely applied in environmental sedimentology to supervise and treat environment pollution.

早期成岩作用研究具有广阔的发展前景，未来可能在以下3方面快速取得突破：研究区域将进一步扩大，湖泊、三角洲及土壤中的相应研究将得以加强；多层的稳态或非稳态的一维、二维或三维的早期成岩数学模型将得以建立；其研究方法和理论成果将被广泛应用于环境沉积学及环境监测和治理等领域中。

Studied pumping well system in this article, the intermediate power transmission parts uesed flexible rod, the downhole assembled rod pump, the ground driving device would transform up and down reciprocating motion into rotating motion. With own mechanism rounded trip for the downhole flexible rod and pump. Wellhead polished rod changed common stell for flexible polished rod. It was a innovation in theory study and craftwork method. It was a remarkable feature in this article, because these innovations were not studied and attempted for prehuman.

本文所研究的抽油系统，中间动力传动部件采用柔性抽油杆，井下配套杆式抽油泵，其地面驱动装置将传统抽油机驴头的上下往复运动变为旋转运动，并且能够利用自身结构对井下柔性抽油杆及泵体实现起下作业，井口光杆也由普通钢质光杆变为柔性光杆，这是理论研究和工艺方法的创新，这些创新都是前人所没有研究和尝试的，是本文的一大显著特点。

This thesis focuses on the conceptions and the relation between the Salvage Charges, the Sue and Labour and the General Average, and other issues related in theory and practice. The aim of the this thesis is to definitude the scope that the above three issues apply to in the practice, and try to provide some relevant advices to perfect the marine insurance justice practice in China through contrast with the relevant practice of the common law of England.

本文将结合英国海上保险的理论和实践对救助、共同海损和施救费用这三者的各自的概念、它们的相关问题以及它们之间的关系进行研究，以明确这三者在实践中的适用范围，并通过对比英国的相关作法，为我国海上保险司法实践的完善提出相应的意见。

The vibro-impact systems are familiar with the non-smooth dynamic systems.The dynamics research of the vibro-impact systems not only is significant in theory but also has practical values in engineering.Firstly,using the Poincaré map method,we get an existent criterion of single impact period-n motion in a two-degree-of-freedom vibro-impact system with damper.It is shown that our conclusions are valid through the numerical simulations.Moreover,the satiability of periodic motions is studied and the correspon...

基于Poincaré映射的方法，通过解析的方法导出了一类具有阻尼的两自由度碰撞振动系统的单碰周期n次谐运动存在性判据，经过数值模拟验证了理论分析的正确性，并给出了分析其稳定性的判别公式，通过数值模拟，讨论系统的局部分岔与全局分岔，同时比较了系统参数变化对其周期运动的影响，发现在强阻尼、弱激励、小质量比、较大恢复系数下系统将会出现较多的有规律的周期碰撞。
