چکیده	We introduce a new method to derive the orbital parameters of spectroscopic binary stars by nonlinear least squares of (o − c). Using the measured radial velocity data of the four double lined spectroscopic binary systems, AI Phe, GM Dra, HD 93917 and V502 Oph, we derived both the orbital and combined spectroscopic elements of these systems. Our numerical results are in good agreement with the those obtained using the method of Lehmann-Filh´es.
