摘　　要：简要介绍突变理论的7种初等突变模型和5种突变指征,结合初等突变模型和突变指征指出突变理论在突变故障中的3种应用方式。综述突变理论在碰摩、气流激振、油膜失稳等突变故障的机制、预测、控制等方面的研究进展,并结合随机突变理论对突变故障的研究方向进行展望。The seven elementary catastrophe models and five catastrophe features were briefly introduced. The three application methods about abrupt faults combined elementary catastrophe theory models and catastrophe features were proposed. The study progress on mechanism,prediction and control about abrupt faults such as rub-impact,gas flow exciting and film unstable were summarized.The study direction of abrupt faults combined with random catastrophe theory was prospected.
