纤维轴线 meaning in Chinese

fiber axis
fibre axis

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，当管道内流动为层流时，分别利用从细长体理论出发得出的纤维二维受力公式和三维分段积分计算方法模拟了大量纤维在流场中的运动，然后在最终时刻统计了纤维的偏角分布，并得出相同的结果：随着re数的增加，纤维粒子的偏角逐渐集中于小角度，即纤维轴线方向越来越集中于流向，此结果与实验吻合较好。
