不幸的是，这种估测没有充分考虑到过去在侵蚀期间沉积速率或地层总剖面损失的差异。
Unfortunately, such estimates did not adequately account for past differences in rates of sedimentation or losses to the total section of strata during episodes of erosion.
河床-河漫滩型和谷底洼地型泥炭沉积物中总氮和总磷含量随着泥炭粒级的减小而明显增加。
With decreasing of peat granule size, the content of TN and TP was increasing obviously in peat sediment of river bed-flood land and valley depression land.
分析发现，饲料总磷含量为0.89%和1.26%时，磷的利用效率和磷沉积系数分别达到最佳水平。
Phosphorus utilization efficiency and phosphorus retention coefficient attained optimal levels at 0.89% and 1.26% total dietary phosphorus by analysis, respectively.
