基于知识的诊断 meaning in Chinese
knowledge-based diagnosis
Examples
- Secondly , the theory of the knowledge - based diagnosis expert system is discussed and a module of diagnosis expert system program is compiled , which has the functions of managing database and fault diagnosis
第二,研究了基于知识的诊断专家系统的理论知识,编制了转子故障诊断专家系统的程序,实现了知识数据库的管理以及故障诊断等功能。 - It covers some important aspects of expert system . the first aspect in research scopes is about the representation and using of inaccuracy knowledge ; the second is to solve the inaccuracy inference by using inference algorithm based on weighted fuzzy rule . the input interface of evidence is designed to use fuzzy theory , so it can avoid the difficulties in traditional method when inputing belief by human the application of database technique in knowledge - based building is discussed in chapter four too
第四章以开发基于知识的诊断专家系统为目的，研究了不精确知识的表示和利用问题；在不确定推理方面，采用加权模糊规则推理，使诊断系统在信息不完全的情况下也能得到合理的诊断结果；设计了获得初始诊断证据置信度的浙江大学博士学位论文接口，加强了对非振动量征兆的利用；提出了基于数据库的知识库建立和维护机制等。 - The main ideas of this dissertation are as follows : chapter one describes the history , status and development of fault diagnosis technique for rotating machinery , and analyses the advantages and disadvantages of some fault diagnosis mehtods , such as nueral network , fuzzy thoery and knowledge - based fault diagnostic mehtods . this chapter also deals with the background and importance of the dissertation . at the end of the chapter , the research contents are gathered up
