aggradation 中文意思是什麼

aggradation 解釋
疊積作用
  1. By the analysis and study, it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently

    然後以實測資料為基礎分析研究了三門峽建庫前後潼關高程的變化規律以及渭河下遊河道的沖淤演變規律，分析研究表明：建庫前渭河下游主槽處于動態沖淤平衡狀態，灘地處于微淤狀態；建庫后，渭河下遊河道發生嚴重淤積主要是由於潼關高程的抬升造成的；潼關高程的抬升主要是由於三門峽水庫的不合理運用造成的，近期不利的水沙條件加劇了潼關河床的抬升速度和渭河下游的淤積。
  2. This prograding complex consists of several small prograding bodies. the transgressive system tract is consist of three retrogradational parasequence sets. the highstand system tract is mainly about aggradation

    層序低位域是在強制性湖退背景下形成的，由三個進積型準層序組構成。
  3. Accordingly, it is urgent and important to study the effect of different tongguan riverbed elevations on aggradation and degradation as well as the flood elevation of the lower weihe river

    因此，研究不同潼關高程對渭河下游沖淤及洪水位的影響具有迫切而重要的現實意義。
  4. Efficiency of permeable pile dike is closely related to water - sand ratio in upstream flow, direction of the coming flow and seepage rate. this paper investigates mechanism and effect of flow control and aggradation using hydraulic modeling and theoretical analysis. it is shown that suitable seepage rate can help aggradation and suitable coming flow direction can help to govern the flow trend

    研究結果顯示，來流和來沙一定的條件下，透水率在適當的范圍內有利於壩后緩流落淤，入流角在一定范圍內對控導河勢有明顯作用，不同方案組合所對應的緩流落淤效果和控導河勢作用具有一定的差異性。
  5. To improve the river reconstruction technique, it is necessary to investigate mechanism and effect of flow control and aggradation for permeable pile dike

    為了探索透水樁壩在黃河治理中的應用前景和應用技術，進一步研究和探討該工程的透水落淤機理和導流效果，為防洪治河提供理論依據。
  6. So, to avoid it, on one hand, the company must take efforts in management, on the other hand, finance leverage can assist to perfect the manage policy of account receivable aggradation

    要遏制應收賬款的沉積，一方面要加強企業內部管理的控制，另一方面要發揮財務杠桿的作用，不斷完善應收賬款的管理政策。
  7. Aggradated plain aggradation plain

    加積平原
  8. Aggradation plain aggradated plain

    加積平原
  9. Analysis of aggradation environment of yima formation of jurassic in gengchun mine field, yima coal field

    耿村井田中侏羅統義馬組沉積環境分析
  10. If there is no efficient way to control the account receivable aggradation, it will be more and more while the quantity of sales is bigger and bigger, and it will affect the normal produce

    但賒銷量過大，內部管理控制不到位容易造成應收賬款沉積數額較多，影響企業正常生產經營。
  11. Finally, by using of the mathematical model, it is calculated and predicted the effect of the different tongguan riverbed elevations as well as the different conditions of incoming water and sediment on the variance of the flood elevation and the tend of aggradation and degradation of the lower weihe river bed. it is answered quantitively the lessening extent of sediment silt and the decreasing extent of the flood elevation of the lower weihe river after 14 years on two different incoming water and sediment conditions with three different tongguan elevations, respectively 328m, 327m and 326m. these results supply important references to the planning of flood control and comprehensive regulations of the weihe river basin

    最後用驗證后的數學模型對不同水沙系列、不同潼關高程（ 328m 、 327m 、 326m ）下渭河下游的沖淤趨勢和洪水位的變化進行了預測計算，從定量上回答了潼關高程從328m降至327m （相當于潼關高程降1m ）和潼關高程從328m降至326m （相當于潼關高程降2m ）時，渭河下游14年之後各河段的減淤程度以及不同流量級洪水位的降低幅度，這些成果對于渭河下游防洪治理規劃的制定具有重要的參考價值。
