Aiming at a class of complex electromechanical systems, such as 4-high or multi-high cold mills and continual mills, we firstly construct mathematical models of every subsystems by means of structural principle modeling method; nextly, get the overall mathematical model of electromechanical drive system by joining together these subsystems'models according to coupling variables and parameters; we finally simplify the overall model according to time-scale principle which can retain main eigenvalues and significant state variables, and obtain a practical mathematical model of complex electromechanical system. By simulating the CM04 temper mill's model constructed by above-mentioned method, we test and verify that the modeling method is effective and practical. The study analyzes and researches the electromechanical coupling facts and acting laws existing in complex electromechanical system.

Although it is possible to have variables and values whose compile-time types are abstract, such variables and values will necessarily either be null or contain references to instances of nonabstract classes derived from the abstract types

尽管可以变量和值在编译时的类型是抽象的，但这些变量和值必须要么为null，要么存储继承自抽象类型的非抽象类的实例的引用。

For firms' adoption behavior, this thesis firstly explains why firms' adoption is in order from the static state by analyzing the regular pattern of firms' adoption behavior; builds control model of firms' adoption decision behavior, and describes the relationship between the stable values of response probability of firms' adoption decision; secondly raises the conception of firms' states from the dynamic state and defines two state variables to explain why and how a firm changes from nonadoption to adoption through the dynamic analysis of the factors influencing the two state variables. Thirdly, constructs the functions of adopting and choosing behavior with mathematical method, which is verified in following.

对于企业采用行为，首先从静态角度剖析了企业采用行为的一般机理用以说明为什么各企业在采用技术创新上有先有后，并建立了企业采用决策行为模型，定量刻画企业采用决策响应概率与动力结构的关系；其次从动态角度提出了企业状态演变概念并定义了两个状态变量，通过对两个状态变量的影响因素分析和动态分析，用以说明某一企业为什么和如何实现由未采用者到采用者的转变；第三对企业采用行为进行定量形式化构造了采用效果函数及选择概率函数等，并得到了调查结果的支持。

We focus on a set of antecedents, including three stimulating variables (limited time buying, limited buying, routine discounting and nonroutine discounting), two situational variables (time available and money available) and individual difference variable.

冲动性购买更是消费者行为与行销活动的主要焦点。

Results Oxygen metabolism abnormality was found after trauma, and it was correlated with ISS, RTS, injured organ or region and number of injured organs, shock, systemic inflammatory response syndrome and respiratory complications. It was more intense in the patients with MODS. There was marked difference in the ratio of change in oxygen metabolism between MODS and NMODS groups. Oxygen deficiency metabolic variables tended to deteriorate in the nonsurvival group. More marked changes in metabolic variables indicated severer organ dysfunction, reaching their peak values before death.

结果 氧代谢水平在创伤后即发生异常，与创伤严重度评分、RTS、损伤器官部位与数量、低血容量性休克、全身炎症反应综合征以及是否并发呼吸系统合并症等有关；并发MODS患者氧代谢水平变化更为明显，与轻伤对照组和NMODS组比较相关氧代谢比值改变差异均有显著性；死亡组乏氧代谢指标常呈持续恶化趋势，其代谢水平改变越显著，预示器官功能损害程度越严重，往往于死亡前达到峰值。

The Newtonian scientific framework where we can prestate the variables, the laws among the variables, and the initial and boundary conditions, and then compute the forward behavior of the system, cannot help us predict future states of the biosphere.

但是这套框架体系并不能帮助我们预测生物圈未来的状态。

Customer segmentation is a critical step to the success of target or segment marketing. The effectiveness of customer segmentation depends on a good number of variables such as customers' demographic, behavioral, geographic, and psychographic characteristics. However, the huge combinations and correlations among variables make customer segmentation a challenging task, even with the aids of information technologies. The industry is desperate for effectual and powerful tool for excavating customer knowledge from the large accumulated data in the corporate database management system.

摘要顾客分群对於目标行销或市场切割的成功与否都是一个重要的关键步骤，顾客分群结果的优劣取决於其所采用的分群因子，顾客分群中常使用的分群因子有顾客的人口统计资讯、行为特徵、地理性资讯与心理方面的特徵等，然而，这大量与因子复合交错的资讯使得顾客分群成为企业的一个挑战，并且渴望寻求一个能够从大量累积的资料库系统中挖掘知识的工具。
