Query: Seyfert Galaxies with Circumnuclear/Nuclear Starbursts   In this paper, we present our preliminary results on Seyfert galaxies with
circumnuclear/nuclear starburst(SB) activity. We have searched the recent
available literature and found 76 active galaxies with clear evidence of
nuclear SB activity, among which 16 are Seyfert 1s, 51 Seyfert 2s, and 9
LINERs. After studying the 51 Seyfert 2s, we find that those Seyfert 2s with
hidden Seyfert 1 nuclei, have similar Infrared-Radio properties as Seyfert 1
galaxies, and are different from "real" Seyfert 2s without a hidden Seyfert 1
nucleus. The later are similar to starburst galaxies.
