The characteristics of metabolic activity based on regularization method.
The temperature recovering curve derived by cold stimulation experiment reveals human inner metabolism status. The errors of the measured data should be eliminated. A Tikhonov regularization method is used in this study to regularize the original data. The results present that the ability of body metabolic function can be measured by the temperature derivative curve, especially the characteristics in the first stage. Two typical shapes of these derived curves reflect the difference of two kinds of blood vessels in clinic. These temperature derivative curves oscillate generally in the last stage.
