明渠水流.河河渠泥沙.含沙量粒度分佈和相對密度的測定Abstract : in light of thicker grain and smaller viscosity of debris flow, a segmented simulation of the debris flow with flume is presented. for the first time. more difficult resistance similarity is brought about by geometric rate without excessive coarsing and discontinuous similarity of sand grain composition in model is eliminated with different grain scale. on this basis the density similarity and sand conveying similarity are achived. the method presented is verified through a model test case
文摘:針對水石流顆粒粗，粘性小的特點，提出了利用水槽進行分段模擬水石流的設想，首次通過幾何變率解決難度較大的阻力相似問題，改變了以往過度加糙的方式;通過變粒徑比尺的方法消除了模型沙級配不連續相似的問題，較好地實現了固體物質級配相似，達到了泥石流的密度相似和輸沙相似.通過水槽概化模型試驗實例，對本方法進行了驗證Changing salinity in the estuary reduces adsorption of cu, zn, cd, co, ni on to suspended sediments within the changjiang estuary. among the metals studied, cd has the obvious salinity depend on kj due to probably its high affinity for cl ", whereas cations competitive adsorption and compexation of onions should be taken into account for salinity effect on cu, zn, co and ni
實驗研究顯示，固-液懸浮體系中鹽度的增大降低了cu 、 zn 、 cd 、 co和ni在泥沙固相中的吸附，其中金屬cd受鹽度影響最為顯著，這與水體中cl ~ -對溶液相中cd的較高絡合能力密切相關。The paper introduces the methods of drying and pycnometer for sediment yield of total precipitation erosion of observation model and validates the reliability of the measurement through check tests of sediment concentration with different particle sizes
摘要介紹了測量模型次降雨侵蝕產沙量的烘乾法和密度瓶法，並通過不同粒徑組泥沙渾水含沙量的對比試驗，驗證了測量方法的可靠性。Even the chemical synthesis model sand can not satisfy the need of silt dynamics research in different similar scale for the expensive self - cost and unchangeable density
而採用合成的樹脂顆粒作為模型沙，成本較高，且過于圓滑，亦不能根據相似比尺的要求調整其密度，給泥沙動力學研究造成不便。Influence of sand grain shapes on dry density of sediment
