【摘要】 在面向对象的有限元程序设计中利用类的继承机制和多态性,可以建立具有共同关键特征的对象家族,实现代码的重用;在保持原有类基本特性的基础上可以通过派生类和虚函数机制,对类的功能进行扩充和裁减,从而实现对有限元软件的扩充。更多还原

【Abstract】 In the object-oriented finite element program, utilizing the inheritance and polymorphism may establish the object family that has the same key features, and can achieve the reuse of the code. On the basis of maintaining the basic characteristics of original class,this programmer can strengthen and reduce the function of the class by means of the inheritance and polymorphism, thereby realize the expansion of the finite element software .更多还原
