选取了太阳附近的100个银河系疏散星团作为一个完整的（数量上）样本，用来推断银河系疏散星团系统的一些全局性质，以便将来与其他星系中的星星星团进行比较。作为数据来源，采用了Lynga的开放星团数据目录第五版。样本的年龄分布的确定，讨论和比较与文献中提供的。通过计算团簇的形成速率、演化衰减速率和演化破坏速率，得到了有关团簇结构和演化的信息。
A set of 100 galactic open clusters in the solar neighbourhood was selected as a complete (in number) sample which is used to deduce some global properties of the system of galactic open clusters, with the future aim of a comparison with star clusters in other galaxies. As a source of data, the fifth edition of the Lynga's Catalogue of Open Cluster Data is adopted. The age distribution of the sample is determined, discussed and compared with those available in the literature. Relevant informations on the structure and evolution of the open-cluster system are derived by evaluating the formation rate of clusters and their evolutionary fading and destruction rates.
