摘　　要：基于灰色系统理论中的关联度分析法,分别对汽轮机在磨削加工时表面烧蚀状态和运行过程中轴承的工作状态进行了诊断分析,给出了不同状态下的关联系数和关联指标,结果表明灰色系统理论方法可有效解决汽轮机的故障诊断问题。The ablative degree of grinding face and the working state of bearing of steam turbine was diagnosed based on the grey cognate analysis the theory of grey system, the coefficient and exponent of correlation under different working conditions were achieved, the faults of steam turbine were diagnosed effectively by using the theory of grey system.
