galactic potential
解釋
銀河系勢-
The 29 f globular clusters in the galaxy are selected as samples in my paper ( the space distribution and motional orbits of the samples have not been researched in detail before. ). according to the basic parameters : azimuth coordinates, distances from the sun, radial velocities and proper motions of sample clusters, the initial positions and velocities of the samples are reduced using the galactic coordinates, and their orbits are integrated by numerical method for three different galactic gravitational potential models
本文選用銀河系中29個累積光譜型為f型的球狀星團作為樣本（這些樣本星團的空間分佈和運動特徵都沒有被詳細地討論過） ，根據它們的基本資料：方位坐標、日心距、視向速度，絕對自行等參數，歸算處理得出了各樣本星團的空間分佈和運動速度。 -
The different galactic gravitational potential have not clear influence upon the perigalactic distance, eccentricity and uncertainty of orbital parameters, but which is significant for other parameters, such as the apogalactic distance, semi - major axis, radial period and azimuth period and so on ; ( 5 ) the monte carlo simulation show that : the distribution morphologies of the orbital parameters which are produced by simulation data are separated into three types : gaussian profile, semi - gaussian profile and non - gaussian profile
不同的引力勢模型對近銀心距、偏心率和參數的不確定度等量影響較小，但是對遠銀心距、軌道半長軸、徑向周期和方位周期等參數影響較為明顯。 （ 5 ） montecarlo模擬的結果表明：根據模擬觀測數據得到的軌道參數的分佈形態大致可分為三類：高斯分佈、準高斯分佈和非高斯分佈；觀測數據對軌道參數的影響與樣本的選取、軌道參數的類型等有關。 -
Besides, considering the differences of the galactic gravitational potential models, there is different influence for the distribution morphologies of all of the orbital parameters of the selected sample clusters
此外，不同的銀河系引力勢模型對所選樣本的軌道參數的分佈形態也有不同程度的影響。 -
Finally the initial observational data are produced by monte carlo method, and the orbital parameters are calculated using the simulation data for the three sample clusters. the relationship between the distribution morphologies of the orbital parameters and the initial observational date as well as the different galactic gravitational potential models are discussed
最後，對3個樣本球狀星團的觀測數據進行montecarlo模擬，並用於計算它們的軌道參數，以及討論軌道參數的分佈形態與模擬觀測數據和不同引力勢模型之間的關系。
