In model , the fare of agc regulation be accounted for in the objective function to achieve the least total purchase cost and the problem solution respects generator constraints , such as ramp rate limits and agc regulation capacity constraints 本文正是基于上述两点考虑，提出了一种计及agc调节容量的机组组合优化模型。模型中考虑了agc的上调、下调费用和机组的agc调节容量约束，从而达到系统购电总成本最小化。
In this article , the author analyses the present situation and the existing problems in different countries from the angles of economy & support from world bank in urban transportation policy - making and traffic problem solutions 本文根据世界银行的调查报告，从经济和金融、环境以及社会性持续发展的角度，分析了一些国家的现状，指出了存在的问题和解决的思路，最后强调了在交通政策的制定方面政府所能发挥的作用，认为应该积极获得世界银行的援助和支持。
On the base of the active sonar theory , this thesis delves into the critical technical of how to design detecting sonar system of under water vehicle , and completely discusses the idea of system designing , the construction of hardware , the problem solution of critical technical and experiment result analysis 本论文基于主动声纳的基本原理，深入研究了水下航行器的探测声纳系统设计过程所涉及的关键技术，结合探测声纳的研制工作，全面论述了系统的设计思想、硬件构成、关键技术问题的解决和实验结果的分析。
Knowledge based design model is the refined quintessence of the designer ’ s experience . in the process of new product development , the reasoning machine is used to calculate problem solutions and the knowledge in the knowledge base is recalled for guidance , therefore to achieve enhanced overall product design level , shortened product development cycle and reduced new product investment risk 基于知识的设计模型是力图将设计者的经验提炼出来,在设计过程中,通过推理机对求解问题进行演算,同时调用知识库中的知识作为指导,从而提高产品设计的整体水平,缩短产品开发周期和减少开发新产品的投资风险。
The verification of the algorithm is performed using a gauss - distributed concentration ball and a stock wave at steady flow in an open channel . the comparison with an analytical problem solution shows that the precision and the stability of quasi - consistence hexahedral element method is as good as that of consistence hexahedral element method , better than that of the linear interpolating function method 6 、比较分析了网格布置形式对圆管流动和台阶突扩流动计算结果的影响后表明，应在物理量梯度变化较大的区域适当加密网格，才能较好地模拟这些区域的流动特性以及壁面对整个流动的影响。
For each project and customer , whether in china or in europe , the excellent aicta team always will be responsible for the entire development cycle , from fieldwork to follow - up services , from product design to serial production , from quality control through production problem solutions 艾柯达的每个项目，每个客户，无论是在中国还是在欧洲，都会有一支优秀的艾柯达团队负责全面跟进，从现场参与到后勤服务，从产品开发到系列生产，乃至生产工程中的监控及问题的解决等各个环节。
In order to probe into the intension of innovative mathematical study , three works have been done . first , we analysized a series of conceptions closed to innovative mathematical study such as " research study " at home and " investigate study " , " discovery study " and " problem solution study " at abroad , at the same time , i analysized the local scholars " three kinds of definition about innovative mathematical study . through distinguishing , comparing and refine , the definition of innovative mathematical study has been appeared 为了探讨创新性数学学习的内涵，本研究做了三项工作：首先，本文对与创新性学习相近的一系列概念，如国内正在推行的“研究性学习” ，国外的“探究学习” 、 “发现学习”和“问题解决学习”等，进行了逐一辨析，同时分析了国内学者对“创新性学习”的三种定义，通过鉴别、比较与提炼，结合数学学习的学科特点，给出了创新性数学学习的定义。
Most economic organization ’ s present mechanism for decision - making is aimed to maintain and promote the stability of the organization . with the historical change and rapid transformation of economic movement and market environment , however , the traditional convention and corporate operation mechanism for problem solution have already been fairly challenged by the market and obviously revealed its limitation 大多数经济组织现行的组织决策机制主要是为保持和增进组织的稳定性而设置的,但是随着时代的变迁和经济活动、市场环境的快速变化,解决问题的传统规则和组织的运行机制已表现出明显的局限性,日益受到市场方面的严重挑战。
According to the basic rules on the equitable and suitable utilization of water resources of international rivers , the basic approaches to the problem solution of the competing uses among the riparian states , and the three basic models of water resources allocation , along with the analyses of the trend and the contradictions of the water resources competing uses in lancang - mekong river basin , as well as the extent of existing cooperation among the riparian states , the present management mechanisms of the river basin , lack of overall river basin development planning , etc . , it is considered that the overall allocation of the water resources throughout the basin is a suitable and practical model of the lancang - mekong river 依据国际河流水资源公平合理利用的基本原则，水资源竞争利用之矛盾解决的基本方法以及水资源的三种基本分配模式，通过对澜沧江?湄公河流域水资源利用的趋势与流域国间的用水矛盾以及现有的流域国间的合作程度、流域的管理机制条件的分析，认为现澜沧江?湄公河流域内，进行全流域水资源全局分配是较为合理和切合实际的分配模式。
