摘要：
The effect of low-intensity noise on the estimate of the probability characteristics of the results of measuring the intervals between acoustic-emission events is considered. Analytic relationships for the probability density of this interval are obtained. Expressions for the invariants with allowance for noise are deduced on the basis of these relationships and allow analysis of the regularities of the influence of noise on the estimates of invariants, elaboration of recommendations for constructing the interval-measurement process, and analysis of particular calculation cases.
