對應一定的初始分佈我們發現無論是冪律的還是對數高斯的球狀星團初始質量譜經過長時間的動力學演化都會得到和現在銀河系觀測到的球狀星團系統相符的對數高斯的質量分佈;動力學演化會明顯地改變球狀星團系統的空間密度分佈,靠近銀心區域的球狀星團瓦解得更多;經過動力學演化后的球狀星團速度分佈函數在靠近銀心的區域明顯得不同於初始分佈,初始擁有較大軌道偏心率的球狀星團更容易瓦解。Standard test method for hydrocarbon types analysis of gas - oil saturates fractions by high ionizing voltage mass spectrometry
