0英文原文：英文原文：Serial CommunicationThis paper introduces the project development framework based on embedded the notion behind, and introduce how IT used for IT project development. Because there are many the same design and development work in different ways, and not always repeat with best practice, so many development framework established. We have defined the concern of problems and application mode, represents the effective solutions of tools. Development framework provides:(1) from the user interface to the data integration application development stack,(2) a framework, basic environment and their related technology, the technology used to use some other framework. Architecture defines a development method, its purpose is to assist customer development project.Software kit for the complicated space dynamic system of nonlinear analysis used more and more in the network platform based on Web, to realize their user interface, scientific analysis, distribution simulation results between scientists and exchange of information. For many application system based on Web access nonlinear analysis of simulation software to become an important component. Network hardware and software changes in technology intensive offers than the past more free choice. Therefore, the reasonable selection of WEB platform for the development of the whole region and the nonlinear analysis and its many applications has become more and more important significance. The current stage of the WEB development characteristic is there appear a large number of open source framework. Web development framework will be referred to a higher level, and that the basic function of the repeated use possible and to enhance the development of productivity.In some cases, open source framework provides no common problem of a solution. For this reason, in the open source development framework established on the basis of their project development framework. This article is to describe a is a Linux based framework, the framework of the use of the open source framework based on Web and help develop the 1application. Through the analysis of the existing open source frame, this paper proposes a new framework, basic environment and they used to improve and use of some other frame the relevant technology. Architecture defines their development method, its purpose is to assist customer development and examples project.Application design should focus on the project in use again. Even with the unique function requirement, also have common mode using the available, which makes them the design and the development can reuse. This paper introduces a “custom“ framework, the framework can be used to define the developers using the same application problems and definition of design patterns. This framework, and we will call it so-and-so development framework, provide a model and tools, set up the industry best practices, make suitable for the application of the common problems. It provides a from of integrated application program said the development the stack. This paper illustrates the application of these problems and mode, tools and industry best practices. So-and-so development framework can according to the needs of the various projects to customize. Its development and configuration is based on Struts, such as are Hibernate, JUnit, and various frame and tools.Web applications have all sorts of design problems, such as performance, commercial logic, access to data and safety. Different code of layer separation design has the following several aspects of the advantage, such as: convenient in maintenance and implementation model of good design ability, choose special tools and ability of the specific problem solving techniques. Will a project the separation between the layer and layer caused the dependencies between layer. For example, a simple use case, it involves the data input and inquires the usually must integrate said business logic and data access to achieve desired function [3]. Therefore, there must be a clear strategy to manage these dependencies. Development framework including design patterns, reusable code and configuration files, make development framework to be used as much as possible. The framework of reverse control are used together to management. Are framework provides a method of each layer integration into a application project. It through context to complete this application are a target, which is an object management strategy depends on between. The use of injection are dependent on technology and intercept are presented here.2We code dependent on the use of object. It is responsible for creating these objects. This may result in tight coupling, but we hope our code is loosely coupled. Rely on injection is a technology that can help us achieve this goal. Rely on injection is a reverse control (IOC) of a kind of form . When application USES depend on, code into will become more clean and easy. This is loose coupling, thus more easy to configure a。
