  7. The evolution time in our calculation is chosen to be 12 gyr, which is the mean value of globular cluster ages in the galaxy

    恆星蒸發對小質量球狀星團的演化起著主導作用，大質量恆星的演化、銀河系核球和盤的沖擊加熱以及動力學磨擦則主要影響大質量球狀星團的演化。
  8. Meanwhile, data from hipparcos satellite shown that the globular cluster might be much further away from us. added to that, a review of theoretical model on globular cluster also prompted astronomers to believe that the globular cluster was not as old as previously estimated

    同時從依巴谷衛星得出的資料顯示，球狀星團的距離可能更遠一些，加上重新檢視球狀星團的理論模型，天文學家相信球狀星團的年並不是最初估計的年老。
  9. Caption : : located in the constellation herculues, m13 is the largest and brightest globular cluster in the northern sky, third in the whole sky, after the omega centaurus and 47 tucanae

    位於武仙座的球狀星團m13 ，是北天球最大最亮的球狀星團，在全天排行第三，僅次於南天球的半人馬座奧米加星團，杜鵑座47 。
  10. 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

    對于冪率的初始質量譜，球狀星團系統動力學演化后質量分佈的轉折點質量主要是由初始質量函數的質量下限決定的，最為適合的值為10 ~ 4m _ ；冪率的初始質量譜的譜指數對球狀星團系統動力學演化后質量分佈的轉折點質量也有影響，其最佳值為1 . 5 2 . 0 ；經過大約5gyr的動力學演化，冪率的初始質量譜就會演化成為高斯的對數質量分佈並具有在隨后的動力學演化中保持對數高斯形式質量分佈的特性。
  11. They usually consist of old stars. some dwarf ellipticals have as few as 10 million stars, and make them not much different from a large globular cluster

    它們通常包含較年老的恆星，有些矮橢圓星系只有約一千萬顆星，和大球狀星團相差不遠。
  12. Our model introduces the general equations of chemical evolution used in galaxies to studies of gcs. in this model the important gas outflow caused by the supernova explosion and other processes during the formation of globular clusters is included. based on such a self - enrichment model, monte carlo method is used to simulate the formation and chemical evolution of globular cluster systems, from which a new explanation of the bimodal metallicity distribution can be given

    本文把星系演化中通用的化學演化方程引入到球狀星團這一系統中來，特別考慮到球狀星團中恆星形成過程中超新星爆發等因素引發的氣體外流，把這一重要的物理過程包含到化學演化方程中，並用蒙特卡羅方法來模擬球狀星團系統的自增豐演化。
  13. If the neutron star is in a globular cluster, it will perform an erratic dance around the center of the cluster, picking up a companion star which it may later swap for another

    如果這個中子星處于球狀星團中，它就會圍繞星團中心作不規則的「舞蹈」運動，俘獲一個「舞伴」 （伴星） ，而且將來還可能更換它的伴侶。
  14. Such a figure caused controversy. the stellar evolution theory states that the oldest globular cluster might have existed for 15 billion years. how could a star be older than the universe

    當時曾掀起一場爭論，因為從恆星演化理論得知，一些最老的球狀星團可能已有150億年的壽命，怎可能星體比宇宙更年老？
  15. Another new small - amplitude red variable star with period of about one day in the globular cluster m

    4中另一顆周期約一天的小變幅新紅變星
