Because of lack of abstraction at the stage of requirement analysis, the traditional Management Information systems of Engineering Designing Project are not suitable to dynamic recomposition of business management process. This paper will combine Workflow Technologies with Management Workflow System of Engineering Designing Project. By decomposing work into good-definitioned tasks and roles and executing and monitoring them according to rules and processes, we can boost efficiency, reduce cost, enhance level of business management of engineering design department.

传统的工程设计项目管理信息系统在需求分析阶段缺乏高度的抽象性，使得最终的需求模型无法适应管理业务流程的动态重组，本文将结合正在研发的工程设计项目管理信息系统集成工作流技术，将业务处理工作分解成定义良好的任务和角色，并按照一定的规则和过程予以执行和监控，达到提高办事效率，降低生产成本，改善工程设计单位生产经营管理水平和竞争力的目标。

The research work presented in this dissertation focused on developing the scheme and techniques of OPCPA. This dissertation gives the results of the theoretical and experimental investigation on OPCPA scheme. The validation of OPCPA at high energy level was demonstrated successfully. And some important results were achieved. Several key techniques related to developing table-top ultra-intense and ultra-short OPCPA laser system were put forward, for example, the generation of femtosecond seeding pulses, the precisely temporal synchronization of the pump and signal pulses, the pulse stretching and recompression, the OPCPA process with high energy conversion efficiency and etc. Based on the integration of these key techniques, a 1.46-TW/153-fs OPCPA table-top ultra-intense and ultra-high laser system has been developed, which, to the best of our knowledge, has generated laser pulses with the shortest pulse duration and the highest peak power among the joule level OPCPA systems in the world.
