Expert systems (ESs) are being increasingly applied to the fault diagnosis of engines. Based on the idea of ES template (EST), an object-oriented rule-type EST is emphatically studied on such aspects as the object-oriented knowledge representation, the heuristic inference engine with an improved depth-first search (DFS) and the graphical user interface. A diagnositic ES instance for debris on magnetic chip detectors (MCDs) is then created with the EST. The spot running shows that the rule-type EST enhances the abilities of knowledge representation and heuristic inference, and breaks a new way for the rapid construction and implementation of ES. 展开更多

Teachers' lesson planning and preparation, which are the most important part of the job of teaching, are the beginning of teaching process. A class cannot be good or well performed without planning or preparation. Referring to the five stages model of Dreyfus(1986) and considering the teaching context of middle schools, the researcher uses qualitative and quantitative methods to get and analyze the data from 96 English teachers in three Chinese middle school. The findings show that in teaching content planning, novice and some proficient teachers cares more about the knowledge and the teaching itself, but the expert teachers pay more attention to the students' abilities and development as well as the knowledge; moreover, the novice teachers are more likely to focus on the teaching aims and choosing of teaching aid. This study also has significance in contributing to the teachers' expertise in planning. 展开更多
