  2. The field observation of the sediments of storm surge produced by no. 11 typhoon in 1997 shows that sedimentation rate of storm surge sediments are greater than that of normal astronomical tide sediments, and the grain size shows relative coarse with poor sorting. vertical sequences of the storm sediment show parallel bedding and overlapped by hummock bedding. these characteristics provide good basis for building the index of storm surge deposit

    通過對梁垛河閘9711號臺風的現場觀測並結合目前已有的風暴潮沉積的研究，分析了風暴潮沉積在構造和結構上的特點，從而建立了正常潮灘沉積中風暴潮沉積的識別標志，同時在野外觀測中還發現即使在風暴潮期間，高潮灘上部仍存在只有淤積沒有侵蝕的地帶。
  3. Grain - size variations of terrigenous sediment sequences in the south okinawa trough

    沖繩海槽南部沉積層序的粒度特徵
  4. Many research such as clay minerals, suspend in the sea, the grain size trend analysis of surface sediment, poc 6 cu and 8 c13 in bottom sediments etc. showed that : the yellow sea warm current divided the south yellow sea into two, the terrestrial material of modern sediment on the west shelf plain mainly came from the modem yellow river suspend carried by the alongshore current, and the sediment difference between the west and east side of yellow sea trough was represented by the sedimentation thickness in postglacial period, sedimentation stratum, and oxygen isotope record

    粘土礦物、碳酸鹽、粗碎屑、海域懸浮體、表層沉積物粒度趨勢分析、 poc c ~ （ 13 ）及底質沉積物的c ~ （ 13 ）等多方面研究表明：以黃海暖流為主導，南黃海堆積陸架平原西側現代沉積物陸源物質主要源於黃海沿岸流攜帶的現代黃河懸移物質，黃海槽東西兩側的沉積差異主要表現在冰消期以來沉積厚度、沉積層序、氧同位素記錄上。
  5. The elemental geochemistry characteristics indicate that elements abundance is controlled seriously by grain size of sediment

  6. Because of the highly variable topological and hydrodynamic condifitions at a strait, the distribution of sediment is complex, with a large gradient in grain size parameters

    海峽地區由於地形和水動力條件多變，沉積物分佈的空間梯度大，有利於揭示不同搬運機制的作用和影響以及評價區域性和局部性的影響。
  7. The distribution pattern can be attributed to ( 1 ) pollution sources located mostly in the eastern coast area ; ( 2 ) the current circulation systems in jiaozhou bay which hindered diffusion of pahs from east towards west ; ( 3 ) sediment grain size and composition factors had an influence on the horizontal distribution

    造成這種東-西差異分佈格局的原因有（ 1 ）絕大部分污染源集中在膠州灣東岸； （ 2 ）膠州灣的環流系統和潮流系統使東部的污染物很難向西部擴散； （ 3 ）沉積物粒度及有機質含量對pahs含量分佈有一定的影響。
  8. Analyses of grain size and mineral components of surface sediments in the offshore area of the northeastern shandong peninsula were carried out to reveal the sediment source and the relationship between the characteristics of grain size distribution and sedimentary dynamic conditions in the littoral zone off the northeastern shandong peninsula

    摘要對山東半島東北部濱淺海區海底表層沉積物的粒度和礦物組分進行了分析，探討了其物源及其粒度分佈特徵與沉積動力條件的關系。
  9. This paper presents effects of estuarine species on sediment geological properties including morphologic, penetration strength and grain size of sediments in diaokou area around the delta of the yellow river

    本文以黃河三角洲釣口區潮灘為研究對象，研究了不同生物密度對沉積物工程地質特徵的改造，包括灘面形態、沉積物強度、以及沉積物顆粒大小的改變。
  10. Ann is a adaptive and non - linear dynamic system made from superposition of many simple components which we call neuron. the question for computation of d _ ( cmax ) belongs to incipient motion of sediment in essence, which is the same question with two different sides, because computation of critical condition ( including critical velocity critical shear stress critical power ) for a grain size under a bed - load condition is equal to computation of a grain size during incipient motion under the bed - load condition and the water flow condition given before. and computation of gross bed - load transport rate has great relationship with standard of incipient motion

    對于d _ （ cmax ）的推求，在本質上還是泥沙的起動問題，因為尋求某種床沙條件下某級泥沙的起動條件（如起動流速、起動切應力、起動功率）和尋求某種水流和床沙條件下的起動粒徑是同一問題的兩個方面而已；而對于推移質總輸沙率推求也和泥沙起動問題中的起動標準選擇緊密相關。
