The components of this paper are listed as follow : ( 1 ) the characteristics of elman recurrent neural networks are introduced . the main course of modeling , including data noise reducing , training controlling and model structure selecting , is proposed . the model ' s performances , when employing different kinds of input data , have been compared 本文的主要内容包括: ( 1 )对elman型回馈人工神经网络模型进行了介绍,并对利用elman型人工神经网络进行洪水预报动态建模中数据降噪、训练控制、模型结构选择等关键技术问题进行了较为深入的探讨,对采用不同模型输入时模型的预报效果进行对比。
The study objects of the paper are used in different stage of the design process in the design method . it is to say that after the target performance level is selected , the deformation control design method is used as the structural design method ; the static push - over analysis method is used as the structural nonlinear calculation method and the capacity spectrum method is used as the structural performance evaluation method . so the unified structural design method of the performance based aseismic design can be formed and the aseismic performances of the structures can be controlled in every step of the design process 该方法将本文研究的各方面内容综合应用于结构设计的不同阶段,即在结构选择了合适的抗震性能等级后,采用结构变形控制抗震设计方法作为结构的设计方法,以结构静力推覆( pusheseeover )分析方法作为结构的计算分析方法,以结构抗震性能评估的能力谱方法作为检验结构实际抗震性能的评估与验算方法,形成统一的结构抗震设计方法,在结构设计的各个阶段控制结构的抗震性能,体现基于结构性能的抗震设计理念。
With the financing structure research of middle - little enterprises under unsymmetrical information , the financing methods and traits are probed into , which adapt to middle - little enterprises , then the deep - seated causes of financing problem are analyzed . with analysis , it ’ s pointed out that the financing of domestic middle - little enterprises take on dualistic structure . the quality of state middle - little enterprises is low - grade ; second , because of discriminating policy and behindhand banking service , the financing need of 论文共分五大主要部分:第一部分探讨中小企业融资的一般情况;第二部分介绍中小企业融资理论,对中小企业融资理论作了详细的描述和分析;第三部分研究我国中小企业融资的现状及制约因素;第四部分是对我国中小企业融资的一般因素分析及结构选择研究,第五部分从定性和定量两个方面作出分析,以验证前文的理论及分析结果。
The economic and social significance of choosing a right structure is , through government ' s control , to have influence directly or indirectly on all aspects in society and economy , including the total social supply and demand structure , the industrial structure , the social technologic constitution , aspects in public affairs and the structure of the ability in social total supply in the future , and so on 财政支出结构选择的经济社会意义在于通过政府对财政支出结构的控制,直接或间接地影响社会经济结构各个方面,包括社会总供需结构、产业结构、社会技术水平构成、社会事业各个方面构成、将来时期社会总供给能力结构等。
The article bases on the softswith experimental network project of the guangdong cnc . it has researched and solved some problems which are met in the period of network establishment utilizing the softswitch faclities of the manufactures . the problems include selecting of softswitch protocol , selecting of network structure , carrier network , encapsulating encode , qos , accesss modes . we choose one from several plans by demonstrating and evaluating with regard to every technological problem 本论文以中国网通广东分公司的软交换系统实验网络构建项目为背景,研究解决了利用设备厂家提供的软交换设备进行网络构建中遇到和需要解决的问题,包括软交换协议的选用,组网结构选择,承载网络实现,压缩方式选择, qos保障,接入方式选用等。
The empirical evidence on factors influencing the debt maturity structure is that asset maturity , enterprise size , debt scale and industry characteristic influence the debt maturity structure in chinese listed companies , we don ’ t have the specific results about enterprise growth opportunity , abnormal earning , abnormal information , and effective tax rate . the results support the agency cost hypothesis partly , and don ’ t support the information asymmetry hypothesis and the tax hypothesis 我国上市公司债务期限结构影响因素的实证研究结果表明影响我国上市公司债务期限结构选择的因素是资产期限、公司规模、债务规模以及行业特征,而对企业成长机会、公司质量、信息不对称程度和有效税率等影响企业债务期限结构的因素没有做出明确显著结果,对代理成本假说提供了一定的支持,对信息不对称假说和税收假说没有提供支持。
Third , through study on the concept of enterprise strategy , relationship between enterprise strategy and organizational structure , choice of enterprise organizational structure , implementation of enterprise strategy and other aspects , the paper illustrates the inevitability to establish international engineering companies of large surveying and designing institutes in our country 第三,通过对企业战略概念、企业战略与组织结构关系、企业组织结构选择和企业战略实施等方面研究,论证了我国大型勘察设计单位创建国际型工程公司的必然性。
