  1. 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,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,通過假設顆粒結合符西安建築科技大學博士學論文合正四面體,建立了絮體結構模型,計算得到的模型絮體分維數基本與試驗中的實際絮體符,在一定程度上能夠映高分子絮凝黃河泥沙生成的絮體結構。
  2. In the synchronous " model, based on the idea of polygonal flux linkage locus, by means of constructing the switch state period table of three phrase voltage inverter is required. in the brushless model, the igbt ( isolated gate bipolar transistor ) switch state period table is gained by gal ( generic array logic ) which analyzes the signal of position feed - back

  3. Abstract : based on the concept of space migration length of photo - activation species, the analytical expression of the total number n of photo - activation species that can reach a segment on the substrate in the cubic deposition reaction space is derived. the simulation of the relationship of deposition rate and position of substrate is also completed. the simulation result agrees with the experiment data well

    文摘:基於光激活物質空間遷移長度的概念,推導出方應空間中到達基片上單面積的光激活物質總數的解析表達,對光化學汽沉積中淀積速率和基片的關系進行了模擬和分析.模擬結果同實驗結果符合良好
  4. Then the coupling beams with new reinforcement layout were made an inquiry into, and the improvement on the seismic behavior by coupling beams diagonally reinforced with a few rows in end regions was found out at last, based on the observations of the experimental phenomena and the analysis of the measurement result, and by the comparison of seismic behavior by making use of hysteretic response, ductility and energy dissipation behavior, a conclusion is presented : the code for design and construction of reinforced concrete high - rise structures ( the draft asked for advise hi 2000 ) ca n ' t ensure that the coupling beams have fairly good seismic ductility ; the result of improvement of the seismic ductility of the coupling beams by the increase hi stirrups besides the strengthen of longitudinal detailing reinforcement was n ' t obvious ; the coupling beams diagonally reinforced with a few rows in end regions have fairly good mechanisms, and the ductility and the behavior of energy dissipation are better than conventionally reinforced concrete coupling beams, so it is suitable to te tised in short coupling beams

    本文通過對三根小跨高比(均為l h = 1 . 0 )剪力墻洞口連系梁在低周復荷載作用下的試驗,了解了嚴格按《鋼筋混凝土高層建築結構設計與施工規程》 ( 2000年徵求意見稿)設計的連梁具有的抗震性能,研究了採取增大連梁配箍量同時加強縱向構造筋的方案對抗震性能的影響,並進一步對新的配筋的連梁進行了探討,了解了在連梁梁端配多排交叉斜筋方案對連梁抗震性能的改善。通過對試驗現象的觀察和量測結果的分析,利用荷載?移滯回曲線、延性和耗能性能等指標對各個試件的抗震性能進行了比較,最後得出結論: 《鋼筋混凝土高層建築結構設計與施工規程》 ( 2000年徵求意見稿)不能保證小跨高比連梁具有較好的抗震延性:通過增大連梁配箍量同時加強縱向構造筋的方案對改善連梁的抗震延性的效果不太明顯;梁端配多排交叉斜筋的連梁具有對較好的受力性能,其延性和耗能性能等各項性能指標均優于普通配筋連梁,宜在深連梁中採用。
