Abstract: A numerical method is proposed for calculating singular integrals. It is shown that the procedure is guite powerful for physics calculations with singularity such as the plasma dispersion function and others. In general, the integrals with more complex singularities can be dealt by this method easily.

Key words: plasma dispersion function, singular integral, quasrature removing singularity
