专家系统是人工智能的一个分支,其发展速度非常快目前专家系统应用领域已经渗透到数学,物理,化学,医学等众多领域,几乎所有的专家系统都至少能将人的效率提高到10倍左右。

本系统是根据人工智能和专家系统的理论知识，利用PowerBuilder9.0开发研制而成的，主要用于实现糖尿病诊断和治疗功能，从而达到利用计算机模拟人类专家诊疗糖尿病的目的。

 本文以糖尿病诊断和治疗的知识为基础，论述了专家系统开发的基本原理，结构，方法和过程，详细阐述了知识库、推理机、数据库、人机对话界面、解释器的设计和实现方法，力求将所学到的知识在专家系统开发中得以全面的应用，并使系统在实际的操作中能按照设计的要求安全有效正确的运行。

Expert system is a branch of artificial intelligence, its development speed is very fast, the application of expert system     already permeate ,such numerous fields as physics , chemistry , medical science ,etc.. Almost all the expert systems can bring people's efficiency up to about 10 times at least. 

This system utilizes PowerBuilder 9.0 according to the theory knowledge of artificial intelligence and expert system.  The purpose of the system is to realize the diagnosis and treatment of diabetes in order to utilize computer simulation human expert.

 The paper introduce the principle and structure of expert system , It explained the design of knowledge base, reasoning machine , database , interactive interface, explaining device and implementation method in detail. During the development the expert system I use all I have learnt to make the system run correctly and eccectively.

Key word: Expert system, the database , PowerBuilder, artificial intelligence
