What the study of the software of configuration analysis of liquid propellant space propulsion systems solved is how to develop the software of configuration analysis of liquid propellant space propulsion systems using scientific software model based on the characteristics of liquid propellant space propulsion systems in order to improve the performance and reduce the mass etc . it ' s important that can save fees and improve corporation ' s ability of participating competition 液体推进剂空间推进系统构型分析软件研究所要解决的问题是如何根据液体推进剂空间推进系统的特点，通过运用科学的软件模型开发液体推进剂空间推进系统构型分析软件。其目的是为了提高推进系统性能、减少推进系统质量等。进行液体推进剂空间推进系统构型分析软件研究对于节约国家经费、提高企业竞争力有着重要的意义。
It puts forward the ways and means of empoldering with component object model . it also designs and realizes substation comprehensive automation system frame and software model which not only have plenty of interfaces including three - layers applied mode and open data , but also have nothing to do with quadratic equipments . 3 ) different objects are distilled from three layers applied mode , and the objects " configurations , dynamic and abstract 提出了运用组件对象模型开发综合自动化系统软件的思想和方法，设计并实现了一个接口丰富、二次设备无关、具有三层体系应用模式和开放式数据接口的变电站综合自动化系统框架和软件模型3 )在三层体系结构中划分了各类对象，给出了主要对象的结构、动态特性、抽象特性。
Traditional information system usually has to change a lot of program due to the alternation of business process , regulation of organzation and people , etc . in order to accelerate the process of system development , adapt to the regulation of office workflow in the process of system running , enhance the system flexibility , we development a set of wfms based on relational database which named jkcflow . this system can be used to the definition , browse , and running control and monitor in the information workflow of office automation . in this article we describe the designing idea and construction method of jkcflow 建设项目管理信息系统的开发过程中对业务流程的管理是系统开发要解决的核心问题，传统的mis系统经常由于业务流程变动，机构和人员的调整及其它一些情况的变化而要做大量的程序调整和修改工作，为了加快系统开发进度、适应办公业务流程在系统运行过程的调整，增加系统的灵活性，我们基于关系数据模型开发了一套工作流管理系统jkcflow ，用于建设项目管理系统中的信息处理流程定义、修改及运行控制和监控。
Then the article analyzes the features of the software platforms , such as j2ee , . net , corba . accordingly , the article build up the system model based the needs of the user . finally , the article implements a software system architecture and a application example based on the software system architecture Net 、 corba )的特点，从而根据用户对分布式测控系统的需求提出自己的系统方案，建立起适用系统模型；最后论文根据已建的系统模型开发了软件系统框架，并在这个软件系统框架上实现了一个具体应用实例。
The other is how to develop the federate based on the hla and make the federate reusable in the whole federation system . this paper discusses how to develop federates in high - cohesion and low - coupling way , how to create a framework about distributing date processing and how to divide the domain development from the hla federate development , which break through the limitation of reused just on the federate and code 本课题从生成联邦成员所需内部模型到联邦整体的开发都力求做到高内聚低耦合,创造性的提取出分布式数据处理的通用框架,同时将领域模型开发和hla成员开发分开,突破了原来成员级重用和源代码级重用的限制,并且开发出的模型均在实际仿真系统中得到了很好的验证和重用。
The construction of the third - party dss model component base increases the reusability of the model , eliminating repeated development of the model and reducing the waste of resources . this component base provides a line of thought for the specialization , industrialization and commercialization of dss model development that is conducive to further development of dss by improving the efficiency of industrialized production of software 第三方决策模型组件库的建立将模型重用推向了一个更广阔的范围，避免了模型重复开发，减少了浪费，为dss模型开发走向专业化、产业化、商业化道路提供了新思路，提高了软件工业化生产的效率，有利于dss的进一步发展。
Secondly , the parameters relative to the performance of se were analyzed according to constant temperature process method . a mathematics model was established based on the analysis results and a software package for performance simulation of se was developed so that the performance could be predicted before a se would be manufactured 其次，采用等温分析法对影响热气机的性能参数进行分析，并且以此为数学模型开发出菱形传动机构热气机性能模拟的软件包，以期在热气机制造以前能对其性能进行预测。
