| Abstract: | Grey predicting model was applied to lubricating oil spectrometric analysis of aero-engine. Based on this model the concentration value of iron element in lubricating oil was simulated and forecasted. Arid to predict fault in time, a way was presented which can predict one-step data after shortening predicting time. The obtained results show that the method is reliable. |
