一种新的状态参数及过程的抽象模型

New Abstract Model for Thermodynamic State Parameters and Processes

发展了一种面向对象的状态参数及热力过程的抽象模型，这种模型可以利用对象的多态性和虚拟方法在没有源代码的条件下被继承、修改和扩充。这种模型的应用可以使得热能动力工程和制冷工程设计中的状态参数和热力过程计算软件的重复使用问题得到简化。

Model for Thermodynamic State Parameters and Processes$$$$ Jiang Huijuan (Department of Civil Engineering, Daqing Petroleum Institute, Anda, Heilongjiang, China, 151400) Abstract A new kind of abstract model for thermodynamic state parameters and thermodynamic processes was developed based on object oriented method. This kind of model can be inherited, modified and enhanced without the source code of the model by taking advantages of the polymorphism and the virtual function technique of the abstract class. With this kind of model, the software used in thermal power engineering and refrigeration engineering for computing thermodynamic parameters of state and processes can be easily reused and enhanced.
