The case-based reasoning is suitable for the solving of large scale, high intelligent and unstructured problems with complicated tasks because it could help us obtain knowledge conveniently, understand easily, and also could enlighten thinking. The case-based method was introduced in quality control field for the offset printing on the basis of the analysis(More)
Aiming at the subjective limitations of the traditional condition monitoring and evaluation methods for the power transformer, the condition assessment method of the transformer state based on the dynamic gray target theory is used to evaluate and diagnose the operating condition and the fault mode of the transformer. The probabilistic reasoning mechanism(More)
Flocculating river water and adding CLO/sub 2/ into the inlet and outlet of the cooling water system can effectively raise water quality, lower turbidity, eliminate alga microorganisms in the cooling water and reach the standard of the cooling water for power plants. In the paper, the effects of flocculation and algae removal in the cooling water treatment(More)

Subject contest is one of the important means to cultivate the ability of “creativity, innovation, and entrepreneurship”, the engineering practice ability and the comprehensive quality for students. At the same time, it plays an important role in cultivating the students' comprehensive quality of learning awareness, autonomous learning(More)
For the life cycle of products, the global unified multidisciplinary model is the core of the simulation optimization. It can effectively organize relative information, manufacturing resources and processes within the life cycle of products. The information has some differences in the content, format and pattern. So a consistent approach to describe the(More)
Based on the equation of small pure electric vehicle (PEV) and the mathematic model of permanent magnet synchronous motor (), synchronous motor (PMSM), the dynamic model is presented for small PEV driven by PMSM. With space vector pulse width modulation (SVPWM) algorithm, a velocity and current double closed-loop simulation model of PMSM control system is(More)
