摘要
本文利用若干疏散星团的实测资料，对近代确定星团成员的不同方法进行了比较和讨论，得到的结论是：这些方法主要用于星团成员的研究可以取得基本一致的结果。合理的做法也许是应该根据星团观测资料的具体情况来选择确定成员的方法。
Based on observational data of several open clusters, modern methods used for membership determination of star clusters are briefly re viewed, and comparisons among them are then made. It can be concluded from detailed discussions that the results for studies on membership of clusters obtained from these main methods are in satisfactory agreement with each other. For such studies, observatiorial errors of proper motions of stars should be considered, adding model parameters concertsed with positions and magnitudes of stars is theoretically reasonable, care must be taken while the position criterion is used, and the non-parameter tech-nique is a new approach. It may be reasonable to choose a proper method to determine membership of a star cluster depending on concrete conditions of obser-vational data of the cluster.
