| Abstract: | A new concept, singular entropy, is brought forward based on the thought of singular spectral analysis, from which, being enlightened by the relationship between signal/noise rate and the corresponding singular entropy, a dramatic idea for reasonably determining the noise reducing order of singular spectrum is presented. |

| Keywords: | Mechanical signal Singular spectrum Noise reducing technique |
