The secondary sculpture is formed by the outgrowth of the outer tangential wall of the epidermal cell, and this kind of protuberance always occurs in the adjoining cells, which makes the laminar protuberances
這些突起是由雌性生殖單位外蓋被表皮細胞的外壁向外突出形成，這種突出生長常常在相鄰細胞之間同時發生，因此，出現片層狀構造。 -
Using the two - equation mode and law of the wall to enclose the equations and avoiding the laminar sublayer, accelerating the solution. 5
對計算模型進行了詳細的闡述，採用雙方程模型和壁面函數法使n - s方程封閉並避開粘性支層，加快求解速度； 5 -
In the laminar flow regime, a analytical mathematical model is obtained by analyzing the film flowing in the wavy wall tube. in the turbulent flow regime, mathematical model almost ca n ' t be obtained directly because the turbulent flow in wavy wall tube is very complex, the model is obtained by quoting some results which are theorized by other studiers. in the part of experimental study, the flow form in the wavy wall tube is observed by transparent quartz glass wavy wall tube apparatus, the evaporation experiments are carried out in a 3 meters steel wavy wall tube, using glucose as the medium, heat transfer is invested, the heat transfer correlations of wavy wall tube evaporator are obtained
數學模型的建立過程中，對于液膜層流流動，直接對波形管內的降落液膜進行理論分析，得出液膜層流流動下數學模型的解析式；對于液膜湍流流動，由於湍流流動的復雜性，再加上所採用的波形管對湍流流動的影響，直接對降落液膜進行理論分析建立數學模型是極其復雜的，通過採用以前一些研究者得到的理論分析與實驗結果，並引入與波形管的形狀特徵參數有關的修正系數k ，建立液膜在湍流流動下的數學模型。 -
4 were calculated in curved tube with permeable arterial wall and effects of parameters, such as shear stress, mass flux of arterial wall, on mass transfer were studied. it was found that steady laminar flow become unsteady with the increase of de. the concentration in inner section of transverse section of the tube is higher than other areas, and with the increase of de and pe, the concentration there increase obviously. it indicates that for the permeable arterial wall, the macromolecules are likely to gather in the areas where axial velocity and shear stress are relatively low, thus indicates why location of atherosclerosis frequently occurs at inner side of curved tube
4 ，在可滲透邊界條件下彎曲血管內的濃度場分佈，並分析了諸如壁面剪應力及跨壁流量等參數對傳質的影響。計算表明隨著dean數的增加，定常層流開始失穩。血管截面內側區是濃度分佈較高區域，並且隨著dean數和peclet數的增加，內側區濃度明顯增大。
