A numerical technique to find out the distribution of the zeros of the partition func-lion in the complex field plane is presented for the lsing model with arbitrary nearest-neighbor interactions. We apply itto the symmetric f J model in two and three dimen-sions and obtain the distribution of the zeros of the effective partition function whosezeros in the complex field plane determine the analytical properties of the configura-lion-averaged free energy. Making use of the results, we discuss some problems of theshort-range spin glass model including the exis1.ence of the Griffiths singularity andthe AT line.
