摘要：
Steep abundance gradients in gas-rich disc galaxies seem to require the presence of unbarred spiral structure. Abundance gradients disappear at the same absolute magnitude that spiral structure ceases, and are considerably shallower in spirals showing a strong bar. This suggests a definite link between the existence of unbarred spiral structure and the origin of abundance gradients.
