摘　　要：选用29个累积光谱型为F型的银河系球状星团作为样本,利用Monte　Carlo方法,结合两种不同的银河系引力势模型对样本的轨道参数进行统计模拟,并画出轨道参数分布图,讨论这些参数的分布形态对初始观测数据及不同引力势模型的依赖性.A sample of 29 globular clusters with spectral type F in the galaxy was selected for statistical study. The Monte Carlo simulations for orbital parameters of the globular clusters in two different galactic potential models were run. The distributions of the orbital parameters were delineated and the dependence of the distributions of orbital parameters on the initial observations was discussed.
