例句與用法
- Mean collision frequency
平均碰撞頻率 - The particle collision frequencies and granular temperature as a function of particle concentration were obtained
得到了顆粒碰撞頻率和顆粒溫度隨顆粒濃度的變化規(guī)律。 - The relation between collisional absorption of the em - wave and the plasma density , plasma collision frequency , and incident wave frequency is obtained
給出了不均勻非磁化等離子體密度、等離子體碰撞頻率、電磁波頻率與碰撞吸收的關(guān)系。 - 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
最后，本文還對(duì)絮凝動(dòng)力學(xué)和絮體結(jié)構(gòu)進(jìn)行了研究，在前人研究的基礎(chǔ)上，針對(duì)高分子絮凝黃河泥沙，對(duì)絮凝過程作了一些符合試驗(yàn)條件的假設(shè)，建立了顆粒碰撞頻率表達(dá)式，應(yīng)用了顆粒數(shù)量平衡方程，從而建立了絮凝過程的動(dòng)力學(xué)生長(zhǎng)模型，模型計(jì)算結(jié)果與試驗(yàn)數(shù)據(jù)對(duì)比表明，二者趨勢(shì)一致，在沒有使用經(jīng)驗(yàn)參數(shù)的情況下基本上能夠描述黃河泥沙絮凝過程中絮體數(shù)量和尺寸分布的變化過程；對(duì)絮體結(jié)構(gòu)的研究中，應(yīng)用掃描電子顯微鏡和透射電子顯微鏡對(duì)絮體進(jìn)行了觀察，將絮體分為絮粒、絮團(tuán)和絮網(wǎng)三個(gè)不同的生長(zhǎng)階段，通過假設(shè)顆粒結(jié)合位置符西安建筑科技大學(xué)博士學(xué)位論文合正四面體，建立了絮體結(jié)構(gòu)模型，計(jì)算得到的模型絮體分形維數(shù)基本與試驗(yàn)中的實(shí)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(jié)構(gòu)。
