摘要
本文利用疏散星团NGC2286天区内25O颗恒星的相对自行及成员概率判定资料，首次对该星团的半径、光度函数以及内部运动等做较深入的研究，分析表明对NGC2286这个中等年龄的星团，正处于动力学演化的初级阶段，在空间和速度上都没有表现出象年老疏散星团M67那样较为明显的分层效应。
Based on the proper motions and membership probabilities of 25O stars in NGC2286 re-gion, the radius, luminosity function and mass segregation of NGC2286 are discussed insome details. It is shown that there seems to be no significant mass segregation in both spaceand velosity for the middle age open cluster NGC2286, being init1al stage of dynamic evolu-tlon.
