abstract:
In oceanic biogeochemistry, the f-ratio is the fraction of total primary production fuelled by nitrate (as opposed to that fuelled by other nitrogen compounds such as ammonium). This fraction is significant because it is assumed to be directly related to the sinking (export) flux of organic marine snow from the surface ocean by the biological pump.
网络释义
焦比
不单是这原因, 还要降低焦比(F-ratio), 如SCT用6.3减焦镜, 焦比由10变为6.3, 那原本要曝光两分半钟才见得到的天体, 现在曝光不足1分钟便可见得到。
