The number density distribution of globular cluster in space will change with time due to the dynamic evolution , especially for those in the central region of the galaxy ; 5 . for the power law initial cluster mass function , the peak value of the mass function after the dynamic evolution is sensitive to the lower limit of the initial mass function we adopt . the suggested value in this paper is - 104m , which is consistent with that reduced from the dynamical analyses for the giant molecular clouds 对于幂率的初始质量谱,球状星团系统动力学演化后质量分布的转折点质量主要是由初始质量函数的质量下限决定的,最为适合的值为10 ~ 4m _ ;幂率的初始质量谱的谱指数对球状星团系统动力学演化后质量分布的转折点质量也有影响,其最佳值为1 . 5 2 . 0 ;经过大约5gyr的动力学演化,幂率的初始质量谱就会演化成为高斯的对数质量分布并具有在随后的动力学演化中保持对数高斯形式质量分布的特性。
