  7. 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。
  8.
