  1. The results show that : 1 ) though the water environment of nanyisan is more muddy than others, algal can still grow ; 2 ) the composition and rock type of the algal limestone are complex, the main rock types include lettuce - like stromatolites, algal reef, digitate stromatolies, wave - like stromatolites and so on ; 3 ) the deposits of algal limestones were formed in low - energy peritidal to subtidal high - energy environment of lakeshore slopes, sliding under the action of gravity and some other factors and become slump mixosedimentite layers ; 4 ) the physical property of algal limestones layers is better than others ; 5 ) the genetic development of the sediment decides that the single deposit is small, distributive and thin - layed

    結果表明，南翼山藻灰巖沉積水體環境相對渾濁，但藻類仍能生長；該區藻灰巖巖石組成及類型復雜，主要的藻灰巖巖石類型有包心菜狀疊層石、藻礁、指狀疊層石、水平波狀疊層石等；其主要為濱岸斜坡上低能潮上環境至高能潮下環境形成的沉積體，在重力等因素的作用下產生滑動或滑塌形成的微生物成因的滑塌混積巖；巖層物性好於其它巖層；藻灰巖層的成因決定了該地區單個沉積體規模小、分散、層薄。

  4. Due to issues of dongting lake districts flood composition, the evolution of sediment flow, the river and lake ( r & l ) distribution characteristic as well as the layout of r & l - dredging engineering, the article simulated the model of the dongting lake terrain change by using the gis technology and adopted the limited volumetric method to establish the two - dimensional hydraulics computation model of lake in order to forecast the water level, the flow capacity, the speed of flow and changes of flow field after implemented the project, which have provided the reliable theoretic basis for the decision - making and implementation of renovation for river course, canal and harbor and river course - dredging engineering

    摘要針對洞庭湖區的洪水組成、水流泥沙演變、河道湖泊水系分佈特點以及河道湖泊疏浚工程布局情況，利用gis技術模擬洞庭湖地形變化，採用有限體積法建立了湖泊二維水力學計算模型預測疏浚工程實施后的水位、流量、流速流場變化，為河道、航道港口整治、河道疏浚清淤等工程決策與實施提供了可靠理論依據。
  5. So far as the alluvial fiver is concerned, the sediment - carrying capacity of flow and hydraulic geometry of river channel can be regulated by regulating the composition of flow rate, silt concentration and sediment ( water and sediment regulation ) during water and sediment discharge ; with which the relative balance for water and sediment discharge and the river channel evolution can be obtained

    摘要沖積性河流的河床在輸水輸沙過程中，調節流量及含沙量和泥沙組成（調水調沙）可以調節河床水力幾何形態和水流挾沙力，追求水沙輸運和河床演變的相對平衡。
  6. 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。
  7. Abstract : sedimentation phenomena in refined oils were descr ibed, the composition, properties of sunflower and canola oil sediments were summa rized. the effects of various factors on sediment formation in oils were also stu died

    文摘:介紹了油脂沉澱現象，綜述了葵花籽油、卡諾拉油等沉澱的組成、性質以及影響其形成的因素，初步探討了防止沉澱生成的方法。
  8. Because the different end members of chinese sediment do not have any absolutely difference in ree composition, so it is difficult to tell from what part did core q43 sediment come only based on ree data

    為了進一步說明柱樣沉積物的來源於中國陸源物質的某一端元，考察了陸源各端元物質的稀土元素組成的差別。它們稀土元素參數平均值有差異。
  9. Based on the comparison between the characteristics of the ree composition of q43 and those of some selected end - members of chinese river sediments, it is concluded that q43 sediment was not merely come from one place
