摘要：

The specific features of using the method of the invariants of acoustic emission (AE) signals for the diagnostics of a pre-failure state are considered. Results of the diagnostics of pre-failure by the amplitude and temporal invariants of AE event stream under mechanic loading of steel specimen are presented. It has been established that the measurement and analysis of amplitude and temporal informative parameters is more pictorial and should be preferred to the direct measurement of invariant relationships. Incorrect application of the method of invariants has been analyzed.
