徑向擴散 的英文怎麼說
中文拼音 [jìngxiàngkuòsǎn]
徑向擴散
英文
lateral diffusion-
The model characterizes many dynamic transport and complexation processes that include radial diffusion, excipient complexation and crystalline drug dissolution
模型利用徑向擴散，輔料絡合作用和晶體藥物的溶出度來表徵多個動力學運輸和絡合過程。The axial and lateral spread of fluid has been likened to and accounted for by a diffusion-type model.
流體在軸向和徑向的散布，已與一個擴散模型聯系起來並用後者加以說明。Firstly, gravel piles in soil were laid for compacting and consolidating soil, then gravel composite foundation was treated with dynamic compaction in order to form three - level soil that is gravel composite soil and high replacement ratio composite foundation and dense composite foundation
該法先在填土層中設置好碎石樁體，利用擠密和排水固結的作用使其得到初步加固，然後對荷載影響深度范圍內的復合土體進行低能強夯處理，迫使樁體碎石沿徑向擴散，形成上部為密實的碎石二合土層、中部為擴徑后高置換率復合地基、下部為整體夯密復合地基的三層結構。Many factors regarding the modifying coefficients of circular and rectangular section are analyzed : ( 1 ) it is theoretically proved that the diffusion coefficient of cl - in concrete is dependent of modifying coefficients ; ( 2 ) through analysis of the results of numerical value calculation, it is discovered that the relation between the modifying coefficients and the thickness of protection layer of concrete is linear, from which the function expression of these two variables is gain ; at the same time, the influence on modifying coefficient of the radius of circular section and the thickness of cl - on the surface of concrete ; based on these, practical calculating method of beginning corrosion time of steel of circular section is set up ; ( 3 ) to rectangular section, the diffusion of cf in concrete is two - dimension diffusion
討論了影響矩形截面以及圓形截面修正系數的因素： （ 1 ）從理論上證明了氯離子在混凝土中的擴散系數與修正系數無關； （ 2 ）通過圓形截面數值計算結果的分析，發現圓形截面修正系數與保護層厚度基本成線性關系，並建立了二者之間的聯系；分析了圓形截面半徑、混凝土表面氯離子濃度對修正系數的影響，從而建立了圓形截面鋼筋初始銹蝕時間的實用計算方法； （ 3 ）在矩形截面氯離子侵蝕下，混凝土處於二維擴散狀態。本文通過計算分析，證明二維擴散的影響區域從邊角開始向中間逐步擴散，並證明了二維擴散影響區域依賴于氯離子擴散系數與氯離子擴散時間的乘積。分享友人
