摘　　要：设备检测具有其重要性和复杂性。该文利用小波分析理论着重分析设备检测信号的局部奇异性 ,提出了一种基于小波分析的设备检测的Lipschitz指数分析方法。该分析方法可应用于设备中出现的无损、撞击、振荡、变形与断裂等状态的诊断中 ,它不仅能定性、而且能定量地分析信号的奇异点、奇异性。在设备检测中 ,必将是一种有很大发展潜力的新方法。The condition detection for thermal systems in power plants is important and difficult.This paper makes use of the wavelet analysis to analyze signal singularity in part.A Lipschitz exponent analysis method based on wavelet analysis is proposed.Using this method to nondamage,striking,oscillation,deformation,breaking and so on,type of damage diagnoses in the thermal systems in power plants.It is analyzed not only determination the nature but also determination the amounts of the singular point and the singular nature.This is a new method with huge potentiality of development in condition detection.
