摘要
为了提高换热设备传热计算系统的通用性和可维护性,提出了一般换热设备的通用算法,讨论了采用面向对象技术开发系统的主要思路。系统开发从面向领域抽象对象开发开始,在抽象对象中完成设备的通用算法和提供对象统一接口,并用抽象对象完成系统框架的构造,在此基础上运用继承性和多态性完成领域实例对象的开发,以达到系统扩充目的。由此开发的系统,不但重复利用度高,而且保证系统的体系结构稳定和可维护性。
For increasing the versatility and the maintenance of the system which is developed to solve the numerical analysis of thermodynamic calculation for heat exchangers, a universal numerical method for general exchangers is put forward, and the outline of the system developed based on object-oriented is discussed, The system developed begins with the domain abstracted objects which is used as elements to construct the system framework, complement the universal method, and define the uniform interfaces of the objects, and then the instance objects of the domain are derived with the inheritance and polymorphism in order to expand the system. The system developed in this way not only has high reutilization, but also keeps good structure stability and maintainability.
