【摘要】 利用面向对象思想和技术处理不同领域的专家知识时，可采取相同的推理机制。因其专家知识的表示形式是相同的：都是由类和对象组成；对象是类的实例；不同层次的类之间具有继承性。据此我们实现了通用的推理机制，由它构成的推理机可用于不同领域的专家系统。由于充分运用了面向对象的继承思想，使得推理速度大大提高，而且结论符合实际。更多还原

【Abstract】 A universal reasoning mechanism can be adopted by handling expert knowledge of different domains with the idea and technology of object-oriented, becanse the expression forms of all kinds of expert knowledge are the same: they are all made of objects and classes,objects are instances of classes, there is a heritable relationship between classes that are dif-ferent layers. As the charactors of above, we have carried out a universal reasoning mecha-nism and completed a inference engine. With effectively applied the heritable idea of object-oriented, the reasoning speed of the reference engine increases highly, and the result is rea-sonable.更多还原
