| 摘 要： | From the evolutionary vector deacription of slowly sime-varyingnoise process,a measure for non-stationarity is developed.It includesboth the non-stationarities of power and of spectrum shape.As a singleparameter,it is a comparable quantity for different processes.Applicationto the analysis of precise gearbox is prescnted. |
