| 摘 要： | 继承是面向对象程序设计方法中的重要特征之一。在分析了传统继承机制不足的基础上，将类比理论引入面向对象，提出了一种新的继承机制－－柔性继承机制。该机制在面向对象程序设计中增加了相似类、相似属性和相似方法的类比应定义及类比分析和推导方法，同时支持子类关系和类比关系，从而可增加灵活而有效地对已有软件进行复用。最后，介绍了支持柔性继承机制的语言ND＿Polya及其支撑系统的设计和实现。

| Abstract: | Inheritance is one of the most important features of object-oriented programming technology. Based on the analysis of the traditional inheritance mechanism, a new inheritance mechanism——soft-inheritance is proposed, which enhances the traditional inheritance by providing analogy definition, analogy analysis and analogy derivation in object-oriented programming. The new mechanism supports both the traditional sub-class relationship and the new analogy relationship and consequently makes software reuse more flexible and effective. Meanwhile, a new self-designed object-oriented language ND-Polya supporting soft-inheritance is discussed and its supporting system is introduced. |
