Scientific paper

The method of principal component analysis is applied to a sample of 41 Galactic globular clusters and 22 younger star clusters to select some age-sensitive or metallicity-sensitive spectral lines.It is found that some spectral lines have great potential to determine the metallicity of star clusters, such as CN, CaII K, CaII H and MgI+MgH; and some other spectral lines are good indicators of age, such as H?, H?, H? and H?. These lines can help us to solve the age-metallicity degeneracy of star clusters.
