  2. Abstract : this paper presents a new model of rain - flow real - time counting method. it has the advanges such as counting easily, not needing the whole loading - time course. and it is also not necessary to readjust or modify the loading - time course. the field loading - time course of the model can be counted directly. the model surmounts the limitation of the previous counting model. it doesn " t need the second stage counting. the above research results have been applied to the data treatment of loading - spectra for the plane engine, the fighter plane and the war tank
