Abstract:  
We will introduce a new method to derive the orbital elements of
the spectroscopic binary stars. Fitting the adopted radial
velocity curves on the measured
experimental data, the corresponding radial acceleration data
are obtained. The orbital parameters are estimated by
the nonlinear least squares of the radial velocityacceleration
curves. This method is implemented for the three double line spectroscopic
binary systems RZ CAS, CC Cas and V1130 Tau. Numerical calculations show that the result are in good agreement
with the those obtained by others using the method of LehmannFilhés.
