英文摘要	We study the correlation between the central surface density and the halo core radius of the dark matter haloes of galaxies and clusters of galaxies. We find that the surface density within the halo characteristic radius r (*) is not an universal quantity as claimed by some authors (e.g., [1]), but it correlates with several physical quantities (e.g., the halo mass M (200) and the magnitude M (B) ). The slope of the surface density-mass relation is 0.18 +/- 0.05, leaving small room to the possibility of a constant surface density. Finally, we compare the results with the MOND prediction.
