摘要論述了多工況斜面沖擊試驗新系統,具有碰撞角度和壁障剛度可調,斜面沖程和沖擊角度可選,並裝有彈性助力系統以提高沖擊強度等特點。By making some assumptions, collision frequency were presented. then the the flocculation kinetics model was established through population balance equation. comparison of experimental data and modeling results indicate that there are the same trend between the two. so the model can predict floes number and size during flocculation of yellow river ' s loess particles without using empirical parameters. the tem and sem were used to obsever floes in the study of floe structure. the flocculation was divided as flocculi, floc and floe aggregate. the floes structure model was established by assumption that particles position in floe accords with tetrahedron. the fractal dimension of model and experimental floes was found to be coincidentso the model can reflect the structure of flocs formed in flocculation of yellow river ' s loess particles by macromolecule flocculant at a certain extent
最後,本文還對絮凝動力學和絮體結構進行了研究,在前人研究的基礎上,針對高分子絮凝黃河泥沙,對絮凝過程作了一些符合試驗條件的假設,建立了顆粒碰撞頻率表達式,應用了顆粒數量平衡方程,從而建立了絮凝過程的動力學生長模型,模型計算結果與試驗數據對比表明,二者趨勢一致,在沒有使用經驗參數的情況下基本上能夠描述黃河泥沙絮凝過程中絮體數量和尺寸分佈的變化過程;對絮體結構的研究中,應用掃描電子顯微鏡和透射電子顯微鏡對絮體進行了觀察,將絮體分為絮粒、絮團和絮網三個不同的生長階段,通過假設顆粒結合位置符西安建築科技大學博士學位論文合正四面體,建立了絮體結構模型,計算得到的模型絮體分形維數基本與試驗中的實際絮體相符,在一定程度上能夠反映高分子絮凝黃河泥沙生成的絮體結構。Optics and optical instruments - environmental test methods - part 13 : combined shock, bump or free fall and dry heat or cold iso 9022 - 13 : 1998
