In this paper, from the point of view of building the fault diagnostic system for spacecrafts, some fundamental concepts of symptom, failure, fault criterion, fault mode, fault model and failure mechanism are given, and difference and connection among them are discussed.
This paper introduces the testing methods of the engine immobilizer system on LEXUS LS430,such as fault self-diagnosis,fault code diagnosis,fault sign diagnosis and voltage testing on power circuit and ECU terminal.
The subject relationship between the auto malfunction omen and reason is fuzzy, therefore, in the thesis we draw fuzzy mathematic method into auto malfunction diagnosis, establish mathematic model of type malfunction diagnosis of auto, bring forward setting up the fuzzy membership grade method which is based on the history data and expert preferential ordinal number, found the fuzzy diagnostic model, and carry out the fuzzy diagnosis on auto malfunction in computer.
The fuzzy relationship between malfunction and portent is analysed based on fuzzy theory and combined with actual operation condition of diesel motor and expert's experience and the fuzzy diagnotic law for diesel motor has been formed. The fuzzy malfunction diagnostic model for diesel motor has been established and finally an example of actual fault diagnosis is given to validate the application of fuzzy theory and means in the fuzzy malfunction diagnosis of diesel motor.
The concepts of the test deterministicity of the fuzzy testing and the stochastic fazzy testing,as well as the relations between the test detenninisticity,the portent-reause membership function and the pro bability density function of the stochastic portent signal are discussed.
The results of long-term hydrological forecast of the Yangtze Basin flood are obtained by analysing the climaticbackground, the climatic portent of weather and some important physical factors in earlier stage, and finally by consulting withexperts.
This paper presents the Hydrochemistry application on exploring the hydrogeologic condition of mine-area, analysing the water-source of water-irruption, monitoring the portent of water-irruption and preventing the mine sudden flooding etc, meanwhile, the methods of solving hydrogeologic problems are introduced with the practical examples
