The expert system, that diagnoses the sensitivity of environmentally assisted cracking (EXENAC; EXpert system for ENvironmentally Assisted Cracking), has been developed using the OPS83 programming language. This system is composed of three independent subsystems, which respectively diagnose the sensitivity of i) stress corrosion cracking of austenitic stainless steels, ii) hydrogen embrittlement of high-strength steels, and iii) hydrogen attack of steels. The knowledge base is consisted of production rules, which have certainty factors, enabling the uncertain but widely applicable knowledge to be built in a knowledge base, which in turn raised the flexibility of diagnosis subjects which the expert system faces with. Applying the developed expert system to round robin tests of the case histories, the diagnoses were accurately made. We discussed the the characteristics of the individual knowledge base, related diagnosis results and the suitable knowledge base structures for diagnoses in the area of environmentally assisted cracking and the improvement methods to increase the Accuracy of the diagnoses.

使用OPS83编程语言开发了诊断环境辅助破裂（Exenac；环境辅助开裂的专家系统）的敏感性的专家系统。该系统由三个独立的子系统组成，它们分别诊断出i）奥氏体不锈钢的应力腐蚀破裂，ii）高强度钢的氢含糖，以及III）钢的氢侵袭。知识库包括生产规则，这些规则具有确定的因素，从而使不确定但广泛适用的知识在知识库中构建，这反过来又提高了专家系统所面临的诊断对象的灵活性。将开发的专家系统应用于案例历史的循环测试，可以准确地进行诊断。我们讨论了个人知识库的特征，相关的诊断结果以及在环境辅助破裂领域的诊断和提高诊断准确性的改进方法的合适知识库结构。
