Applying the software ADAMS for dynamic simulation and Pro/E for three-dimensional design creates the mechanical system of virtual prototyping model of the 200t crawler crane. The models of the drag bar, the spring backstop, the luffer rope and the crawler in the system are established well by ADAMS/View module. The dynamic simulation of the complete mechanical system is researched at series of work condition, which occurs possibly the crawler crane boom backward tipping as the crawler crane unloads suddenly.

Among n web pages, access probability increment will decrease from the first web page to nth web page. Web pages above n will be accessed less frequently then ever. We analysed a Web server log and two proxy server logs. Analysis mainly focus on Web page request distribution, Web static document size distribution, Web static document access distance distribution, Web static doment access intertime distribution.

对一个典型的Web服务器和两个代理服务器的日志进行了分析，并将Web页面请求分布、Web静态文档大小的分布、Web静态文档的访问距离的分布、Web静态文档访问间隔时间分布同既有文献的结果进行了对比，有些结论是相同的，有些不同，可以视为我国WWW访问所特有的访问特性。

In this thesis, how to study and apply of system of CRM based on Web are discussed. Firstly, we summarize the principle of CRM, beginning with the current research condition, and introduce the concept, features and management principle of CRM. Secondly, we illustrate the basic architecture of web-based CRM system to form the basis of the further research and propose the integration of CRM system to the front end of enterprise, namely, the study on the business process re-engineering of CRM system. Then we discuss the key technique knowledge on CRM system based on Web, which included the technology of system interface, system safety and the design of net framework. And explain the technology of web service is a good solution to the problem of system interface in the Internet and the advantage of the develop way based on the B/S pattern. According to an application of CRM system based on Web, this thesis explains how to set up a CRM system based on Web, which include the customer requirement, analyzing the business process, system framework and system safety. At last, this thesis puts forward the extensive foreground of the system of web-based CRM with the expanding of the web technology and explains that there are some questions are to be resolve stilly in this thesis.

本文的研究内容首先从客户关系管理的研究现状出发，对客户关系管理加以概述，阐述CRM系统概念、系统特点和核心管理思想；并阐明了基于Web的CRM系统的基本架构为进一步的研究作铺垫，提出CRM系统对企业前端的整合，即对CRM系统的业务流程重构的研究；接下来说明基于Web的CRM系统开发的关键技术，包括系统体系结构的选择，系统接口以及系统安全三方面的技术要求，具体说明了B/S模式的原理及优点，Web Service是解决基于B/S模式系统的接口问题的最好方案；然后以一个销售管理CRM系统为例，说明如何构建一个基于Web的CRM系统，包括了系统设计要求、系统实现、系统功能框架和系统安全机制；最后根据当前通信和网络技术的发展，展望基于Web的CRM系统应用的广泛前景，并对在本文研究中还存在需要改进的地方进行了探讨。

The bar chart to the right illustrates just how sharply sales of crawler dozers have grown since 2002. For both dozers and loaders, sales fell flat in 2002- by our estimates dropping to approximately 9,450 units of crawler dozers and about 1,200 units of crawler loaders -from peak sales in the late 1990s.

右边的图表清楚地显示了自2002年履带式推土机销量的快速增长情况。2002年推土机和装载机销售没有增长——据我们估计履带式推土机的销量会从九十年代末的顶峰降到大约9450台，履带式装载机会降到约1200台。

The hydraulic system model of the hydraulic cylinder backstop, which in general used on the large-tonnage crawler crane, is established by ADAMS/Hydraulics module. And the joint simulation between the mechanical system and the hydraulic system of the crawler crane virtual prototyping is implemented. The different effect of the spring backstop and hydraulic cylinder backstop for the crawler crane boom backward tipping is analysed and compared.
