In this paper are calculated the large scale mass fluctuations and peculiar velocity fields in cosmic string scenarios in different dark matter dominated universes. 本文在宇宙弦模型中,计算了各种暗物质主导(MD)宇宙的大尺度均方质量扰动和速度场。
The feedback effect of supernova explosions on dwarf galaxies in the cold dark matter dominated universe is studied. 讨论了在以冷暗物质为主的宇宙中,超新星爆发对矮星系演化的反馈作用。
Mercury in suspended matter is dominated by mercury bound to humus, because the strong combining ability of humus, this can be reference for mercury pollution harness. 悬浮物中汞以腐殖质结合态为主,这与腐殖质对汞的螯合能力甚强,能对汞污染起自净作用有关,这对汞污染治理有参考价值。
Arsenic in suspended matter is dominated by Ca-As and O-As; the content of A-As, Al-As and Fe-As is very low. 悬浮物中砷以Ca-As和O-As占主导,A-As、Al-As、Fe-As含量均较低。
The organic matter is dominated by ⅱ and ⅰ types. 有机质类型多为Ⅱ、Ⅰ型。
