摘要：

Two extensions to the utilisation of the coherence function for isolating components of power-spectral-density measurements are derived and tested. The conventional coherence method is briefly reviewed first, followed by the presentation of the new extensions to the method. The use of the latter is illustrated in the removal of contaminants from measurements of wall-pressure spectra, in pipe flow and bundles of cylinders in turbulent axial flow. © 1992.
