ON THE OPTIIMAL REACTIONS ASSEMBLAGE OF COMPLEX REACTION SYSTEMS

In this paper, the author analyzes distinguishing features of complex reaction systems and single reversible reaction, and optimizes complex reaction systems starting from set theory.The method of constructing the optimal reactions assemblage and calculating the potential maximum equilibrium yield (PMEY) of objective products is proposed here. This paper points out clearly that the euqilibrium yield of objective products calculated by means of conventional method is the global equilibrium yield (GEY).It is not the thermodynamic constraint, and could be exceeded by observed yield of objective products; only PMEY is the thermodynamic constraint. It gives information on potential and possible optimal yield and thereby improving production. This paper also points out the way in which the real complex reaction system approached the optimal reactions assemblage. The new concept of PMEY and optimal reaction assemblage proposed by this Paper is universally applicable for the important complex reaction systems, such as the pyrolysis of alkane to produce ethylene, steam reforming of methane to produce syngas, production of formaldehyde from methanol, epoxidation of ethylene to produce ethylene oxide, hydrogenation of benzene to produce cyclohexane.

波动性比率与涨跌幅限制实证研究

从交易机制的角度解释了股市开盘收益率的波动大于收盘收益率的波动的原因。在考虑了涨跌幅限制的存在对股票价格行为的影响后，建立了一个简单的计量模型，提出涨跌停频率的大小与波动率的正相关关系及涨跌停日的日内收益率与次日隔夜收益率的正相关关系的假设，并就中国股市的情况进行了实证分析，得出了与假设一致的结论。这里的研究为“方差比率之谜”提供了新的解释思路。

吡咯、苯甲醛在酸催化下生成环状中间体,不可逆的转化生成TPPH_2与TPC;在硝基苯存在下TPC被氧化成TPPH_2。     

平面机构运动数字化控制系统的设计

介绍了平面机构运动数字化控制系统的设计，其设计主要是对机械原理实验室中平面机构运动演示板进行改进，从原来的以单片机为控制核心到以微机系统为核心，系统控制本质是通过对解说语音文件的操作来达到对126个机构进行任意的操作，并且在性能上实现了易调试、可视化、多媒体等特点和功能，使教学效果得到显著提高，同时对于工业网络控制也具有一定的借鉴作用。     

论激励机制在国有企业中的运用

介绍了激励管理的内涵,并就国有企业如何建立和运用高效的激励机制,调动员工的积极性,提高企业的劳动生产率,增加企业的经济效益进行了分析探讨。     

企业内部劳动力市场理论对国有企业改革的借鉴意义

完善的企业内部劳动力市场对于内部员工激励具有重要作用。由于人才的不断流失,当前形势下建立并完善内部劳动力市场,对于国有企业改革具有重大的意义,而其关键在于变内部劳动力市场的混同均衡为分离均衡。

一类供应商逆向选择问题的报酬机制研究

研究了采购企业在缺乏供应商实际业务能力、服务成本等方面信息的情况下 ,利用博弈论显示原理设计不同的供货合同来让供应商选择 ,从而根据供应商的选择结果来判断其真实的能力或类型 ,从而避免了供应商逆向选择问题的发生 .通过分析 ,得出了最优报酬机制的特征 ,并证明了上述报酬机制下的最优合同与采购企业对供应商综合能力和成本的先验认识无关 .     

Technical Notes ：STUDIES ON THE VALUE OF SECONDARY MARKET TO THE SUPPLY CHAIN

This paper investigates the impact of a secondary market, where retailers can buy and sell excessinventories, on the supply chain. We develop a two-period model with a single manufacturer and tworetailers. At the beginning of the first period the retailers order and receive products from themanufacturer, but at the beginning of the second period, they can trade surplus products betweenthemselves in the secondary market. We investigate the impact of the correlated dependence ofretailers' demand on both the quantity effect and the allocation effect under the secondary market.Lastly,we study potential strategies for the manufacturer to increase sales with the existence of thesecondary market.
