  1. According to non - newtonian fluid mechanics theory and mathematical method, conbined with plunger moving property, the hypothesize fluid is imcompressive, hydraulic radius of flow of liquid in crevice is very little, and it is laminar flow, the flow is treated fixed continuous flow at every instant position of plunger, equation of motion and boundary condition were set up in condition of concentric and eccentric of pump barrel and plunger

    運用非牛頓流體力學理論和數理方法，結合抽油泵柱塞運動特點，假設液體為不可壓縮的，液體在縫隙中流動的水力半徑很小，呈層流流動，柱塞在每一位置的瞬間，流動做定常流處理，建立了泵筒與柱塞同心和偏心兩種情況下運動方程和邊界條件，引入無量綱坐標、無量綱速度和柱塞與泵筒偏心配合時的縫隙高度，並給出縫隙流流速、流量的解析解。
  2. Firstly, when the pipe flow was laminar, the movement of fibers was computed in the 2 - d force formulae that were deduced from the slender body theory and in 3 - d integral method. results revealed that angles between fibers " axis and the orientation of flow would concentrate gradually on a low number as the re numbers increased. that is, the axis of fibers would rotate toward the orientation of flow

    首先，當管道內流動為層流時，分別利用從細長體理論出發得出的纖維二維受力公式和三維分段積分計算方法模擬了大量纖維在流場中的運動，然後在最終時刻統計了纖維的偏角分佈，並得出相同的結果：隨著re數的增加，纖維粒子的偏角逐漸集中於小角度，即纖維軸線方向越來越集中於流向，此結果與實驗吻合較好。
  3. The lubrication theory of the couette laminar flow between two concentric cylinders

    環隙科特層流潤滑理論
