    3對細顆粒泥沙絮凝沉降的影響
  14. It is suggested in this paper that the sediment of the high stand system tract is mainly composed of fine - grained sediment, hardly of the large scale of fluvial - delta because of the low dip of the ramp, low subsiding rate and low sedimentary rate in basin

    研究表明，盆地基底沉降幅度小、坡度極為平緩、沉積速率很低，因此導致層序內的高位體系域多以細碎屑沉積為主，大型河流三角洲沉積基本不發育。
  15. Seagrass beds or fine sediment bottom

    海草床或幼細沉積物海底
  16. The two characters sharply enhanced the rate of sediment, then h1 descending, and there were several peaks in the curve of h2. the fine structure and stable aggregates deferred the destroy of soil surface structure, and the change of sediment was slow
