This article describes a common physical experiment for teachers to test the students to examine and usually questions can apply computer programs - expert system. Starting from the design idea of the system, this paper introduces the structure of the knowledge base and the reasoning mechanism of the system. First, the expert system design expert system is designed to simulate the outstanding experimental teachers on the experimental teaching and examination conducted by students, test objectives should be achieved. Therefore, the system should include the following: For a certain experimental topic, students should be required to grasp, understand, understand those original
