峭度指标是非平稳信号故障诊断的重要参数。峭度指标对信号中的冲击成分十分敏感，冲击成分能量越大，其峭度值就会越大，在故障诊断的时域分析中十分重要。本文件中将其独立做成了一个子vi，便于程序直接调用。(Kurtosis index is an important parameter of non-stationary signal fault diagnosis. The kurtosis index is very sensitive to the impact component in the signal. The greater the energy of the shock component, the greater the kurtosis of the signal, and it is very important in the time domain analysis of the fault diagnosis. This document will be independent of a sub VI, to facilitate direct calls to the program.)
