英文摘要 | For 163 metal-rich Quasars, the m(v)-logZ diagram shows a very close correlation. Using multiple regression analysis for these sources ( N = 163), we obtained q(0) = 1.142 and correlation coefficient gamma = 0.69. These results suggested that the Universe is closed and all metal-rich quasars are of a single category. On the other hand, the evolution is very small at Z less than or equal to 2 for metal-rich quasars. |
