恒星的初始-终止质量关系

本文研究了星族ＩＲＧＢ／ＡＧＢ星外壳结合能为零时的核质量与其初始质量的关系，发现此关系与Ｗｅｉｄｅｍａｎｎ和Ｋｏｅｓｔｅｒ观测得到的初始终止质量关系相符，并与Ｚｈａｎｇ和Ｋｗｏｋ得到的行星状星云核质量分布的观测结果相符合．采用相同的假设，本文还得到了星族ＩＩ恒星的初始终止质量关系．对于相同的初始质量，星族Ｉ恒星的终止质量比星族Ｉ的大～１０％－２０％．

规范耕地的自由流转是保护耕地质量的有效途径

中国经济的飞速发展，带来了城市化进程的加快，与此相对的是中国人口总量以每年1000多万人的速度激增，人地矛盾日益突出，同时大面积的生态退耕也给耕地面积扩大带来更多的压力，耕地面积的持续缩小将成为不可逆转的趋势。因此，耕地总量动态平衡很大程度上依赖于耕地质量的提高，至少要维持现有耕地质量不能下降。
