| Abstract: | Variations of geology and astronomy have constantly parameter variable auto-correlation function of vibration attenuation type. This paper puts forward a suit of initial value determinate method of separated periodic to go on nonlinear fitting for this type of autocorrelation function. An actual example is taken to illustrate that fitting precision of separated period is 17~28 times larger than non-separated period and the fitting of separated period has good effect. |
