摘要：
We have obtained CCD BVRI colour-magnitude diagrams for a series of disk globular clusters, improving parameters end detecting anew one: Lynga 7. Using the magnitude difference between turn-off and horizontal branch Delta(TO-HB) as an age discriminator, and their spatial distribution we compare old disk open clusters, young halo globular clusters, end metal-rich disk globular clusters, obtaining clues to the Galaxy formation process.
