Towards the research on two flood water of yuhe river in datong city during 2004, by measuring and comparing their discharge, sediment concentration 、 nutrient include organic, phosphorus, potassium, azote, the result shows that the nutrient content of the sediment is greatly larger than that of supernatant fluid
摘要以2004年大同市御河乾渠兩場洪水為研究對象，對其流量、含沙量、養分（包括有機質，氮，磷，鉀）做了測定和比較，研究結果表明：洪水中下層泥沙中的養分含量遠大於上清液中的養分含量；洪水中整體養分含量隨著含沙量的增大而增大，並且養分含量和含沙量呈近似線性關系。 -
And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity, showing cn bear the efficient capacity of control soil loss. nevertheless, when soil is saturated, the runoff intensity of both tillage systems is near, implicating cn has the limited function of reducing runoff. 2 ) based on the case analysis of observed all rainfall - runoff generation processes, a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils, which is attributed to the property of rapid water sorption and much non - capillary porosity
經近幾年的觀測和理論分析，取得了以下結果和創新的認識： 1 ）在降雨強度較大的情況下，保護性耕作制? ?聚土免耕的產沙強度明顯較常規耕作制? ?順坡耕作的小，說明聚土免耕耕作制防治土壤流失是有效的；但當土壤達到飽和后，聚土免耕的徑流強度與常規耕作的差異較小，產沙強度也增大，因此，聚土免耕防治水土流失的能力是有限的。 -
Taking the suspended sediment as the sand for the experiment and the normal nutritive matter - phosphorus in water as the contamination for simulation, the effect on the equilibrium adsorption of phosphorus from the initial concentration of the water phase phosphorous pollutant and the influence of sediment content on the isothermal adsorption of phosphorus are studied through the experiment
摘要以懸移質泥沙為試驗用沙，以水體中常見的營養物質磷為模擬污染物，通過試驗研究了含磷污染物水相初始濃度對磷平衡吸附量的影響和含沙量對含磷污染物吸附等溫線的影響。 -
The activity area of sediment and solution in gooey is distributary river, which has gigantic water power, good degree of sorting and roundness, gruff grain. lower mud and mica content
分流河道的主體部位水動力較強，分選性和磨圓度較好，粒度粗，雲母礦物和泥質含量較低，是膠結物沉澱和溶解的活躍區，因而也是物性相對較好的地方。 -
The fundamental theory and equations for the pressure fluctuation are described and the wall pressure fluctuation is measured. based on the experiment data, the characteristics of pressure fluctuations are analyzed in the three - phase flow of water, air and sand. the effects of air concentration and sediment content on the amplitude and frequency of pressure fluctuations are discussed
建立了多相流壓強脈動基本方程，闡述了水流脈動壓強基本理論，分析了壓強脈動機理；根據試驗數據，探討了水、氣、沙三相流體的壓強脈動特性，初步得到了高速含沙摻氣水流脈動壓強的幅值特性與頻域特性；提出了脈動壓強強度系數、脈動壓強極差系數與含沙量、摻氣濃度的關系。
