In this paper, we present a discrete fractional Hilbert transform. This method analyzes the mutation signal in detail according to the order of P. We also can analyze and extract the local information of the signal according to it. We know the difference between the square wave signal and the sine signal by the way of fractional Hilbert transform. And this method is applied to the identification of gas-liquid two-phase flow. We analyze the variation of the marginal spectrum under different orders of the two phase flow signals, and get a better performance of flow pattern recognition.
