- 本文对旋转机械振动故障预 测方法进行了初步研究，分析了传统预测参数的不足，提出了以分时尺度矩为预测故 障参数的两种故障预测模型:分时尺度矩趋势预测模型和分时尺度矩波动预测模型。 根据分时尺度矩的变化不仅能够判断是否发生了故障，而且能够判断故障的种类。典 型故障实测数据的预测结果验证了基于分时尺度矩预测参数的灰色模型故障预测算 法的有效性。 -This paper the grey correlation analysis method and the probabilis

PCI
- PCI作为一种稳定的高速的设备扩展总线，因其良好的可扩展性和兼容性使其经历了20多年的使用，PCI协议规范不断扩展、更新。现在更有PCI-X、PCI-E总线的不断涌现，虽然说它们与PCI总线不能够兼容使用，但它们无疑都是都在PCI总线的基础上发展而来的。-PCI as a stable high-speed device extension bus, because of its good scalability and compatibility make its experience in
