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。The feasibility and some advantages of employment of sil have been discussed. the numerical aperture are calculated when laser pulse is defocusing. in contrast with traditional microscopy objective, the employment of solid immersion lens can effectively increase the numerical aperture of the recording system ; thereby it can increase the volumetric density and decrease the demand of the incident laser power
當脈沖聚焦點相對于固體浸沒透鏡底面離焦時,對系統的有效數值孔徑進行了計算,結果表明採用固體浸沒透鏡離焦的方式進行記錄,系統的有效數值孔徑最低可增大到固體浸沒透鏡插入前的折射率倍,其數值孔徑的理論極限值為存儲介質的折射率。By means of sem, tem, laser scattered particle analyzer, etc., the formation mechanism of ultrafine sio2 particle was studied. it was found that at the initial stage, the sio2 particle consisted of some minicrystal, but after the initial stage the sio2 particle was formed by some soluble aggregated substance growing on the surface of the early particle
運用掃描電鏡、透射電鏡、激光粒度分析儀等檢測手段,探討了體系中超細二氧化硅顆粒的形成機理和過程,指出超細二氧化硅粒子前期是由體系中的微晶核組成,中後期則由體系中的可溶性縮合物在其表面生長而成。It can be concluded that the elevated ability of penaeus immune system is realized via increasing po production instead of increasing of unit enzyme activity of po. since the biggest number of hemocytes, semigranular cells and po production have been obtained after - 1, 3 - glucan and lps stimulation, it implies that the - 1, 3 - glucan and lps would be the most efficient immunostimulant on shrimp, penaeus chinensis, among the immunostimulants used
透射電鏡下的觀察結果表明,中國對蝦血細胞的超微結構在免疫刺激前後也發生了變化,三種血細胞的糙面內質網、核糖體和線粒體的數量均有一定程度的增加,其中以小顆粒細胞和大顆粒細胞的超微結構變化幅度最大。In former stl instruments, a laser beam with a gaussian distributed intensity was commonly used as the excitation source. nevertheless, the output of a high power laser is usually a superposition of multi - modes rather than a gaussian distribution ( tem00 ). therefore, it is very convenient to add an aperture to get a top - hat beam
以前的表面熱透鏡裝置中,多使用高斯光束作為激勵光,但由於高功率激光器一般為多模輸出,要獲得嚴格的基模高斯光束比較困難,而平頂光束可以通過在激光器前加一定大小的光闌實現,降低了對激光光束質量的要求,更有利於實際的測量。At present, photothermal deflection technology and surface thermal lensing technology are widely applied in weak absorption measurement
