| Abstract: | In this paper the authors first derive the expression for the theoretical resolving limit form the overlapping distributions of interference and spectral intensities.Then we discuss the conditions for the stable solution to that integral equation under consideration.Again the comparison between the resolving powers in multiple-slit diffraction spectroscopy and in the classical diffraction spectroscopy is given.At last, as examples, we present the results of several computing experiments, which is coincident with our conclusions. |
