Comparing with the current observations, which include the number density distribution in space, mass function, etc., the so - called standard modes for both the power law and gaussian cluster initial mass functions are selected among many runs of simulations. the deviation from the standard modes, which is resulted from the change of the parameter for the initial conditions, is discussed in detail. the discussion of the model parameters is also presented although they are adopted as the typical values based on previous work
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。These rivers have not shown such positive gains over the past two decades as those achieved by the rivers indus and beas. the pollution load of the rivers has certainly been significantly reduced as a result of the livestock waste control scheme and implementation of wpco controls after december 1990. however, large numbers of farms remain in the catchments of the river ganges, yuen long creek, the kam tin river and tin shui wai nullah
天水圍明渠及錦銹花園明渠的水質近年來並沒有像梧桐河和雙魚河一樣顯著地改善，雖然政府於1990年12月推行了禽畜廢物管制計劃及實施水污染管制條例，河道的污染量有所減少，但平原河元朗河錦田河及天水圍明渠集水區一帶尚有許多禽畜農場，加上區內不少鄉村尚未設有公共污水管道，因此污染問題並不容易解決。
