  10. To search for high - velocity molecular emission toward massive star formation regions, and to study the connections between h2o masers, iras objects and outflow properties, we carried out a co observation for a h2o maser sample. we found that most of the objects have excess high velocity emission produced by outflows ; we find a significant correlation between co line full widths and iras luminosities. the widths are proportional to the iras luminosities

  13. Interstellar dynamics ; molecular outflows ; jet ; star formation

    星際介質動力學分子外向流噴流恆星形成
  14. The high metallicity of disk gcs was caused by the particular environment they are situated. because of the strong interaction wjth the disk, the extent of outflow and star formation efficiency ( sfe ) of the disk gcs was quite different from the halo gcs, which leads to the significant difference between the metallicity distribution of two classes of gcs

    本文建立的自增豐演化模型對球狀星團的余屬度雙峰分佈提出了一種新的解釋，指出盤族球狀星團之所以出現較高的金屬度，是因為它處于銀盤這一特殊的環境下，與銀盤相互作用而造成比暈族球狀星團更為強烈的增豐。
  15. It is thought that the expulsion of matter from a galaxy during bursts of star formation is one of the main ways of spreading elements like carbon and oxygen throughout the universe
