针对机械行业变转速零件如轴承，齿轮箱的故障诊断，采用阶次分析技术。程序针对变转速工况下的故障诊断。-Variable speed machinery industry parts such as bearings, gearboxes for fault diagnosis using order analysis techniques. Procedures for troubleshooting variable speed conditions.

轴承故障诊断，自己编写的基础EMD分解程序，实测很好用。(Bearing fault diagnosis, self-compiled basic EMD decomposition program, the actual measurement is very useful.)
