摘要This paper is the fourth in a series presenting spectrophotometry of 51 globular cluster candidates, that were detected by Mochcjska et al. in the nearby galaxy M33 using the data collected by the DIRECT project. The frames of M33 in this study were taken as a part of the BATC Multicolor Sky Survey. We obtained the spectral energy distributions of these candidates in 13 intermediate-band filters. By comparing the integrated photometric measurements with theoretical stellar population synthesis models of Bruzual and Chariot, we estimated their ages. The BC96 models provide the evolution in time of the spectrophotometric properties of simple stellar population for a wide range of stellar metallicity. Our results show that half of the candidates are younger than 101 years. We also find that globular clusters formed continuously in M33 from 4 x 10(6) to 10(10) years. Our results are in agreement with Chandar et al. who estimated ages for 35 globular clusters candidates from our list by comparing the photometric measurements to integrated colors from theoretical models by Bertelli et al. The Kolmogorov-Smimov test shows that the maximum value of the absolute difference of estimated ages between Chandar et al. and us is 0.48, and the significance level probability is 100.00%.
