对流动槽中经过不同入口流速冲刷稳定后的ＥＣ（内皮细胞）表面的切应力分布进行数值模拟，视单个ＥＣ为一条二次曲线，多个ＥＣ的连续分布为此二次曲线的周期拓延，随流速的增加．ＥＣ有沿动流动方向的伸长及细胞质沿流动方向的前移．结果表明：切应力随ＥＣ的形状呈现相同周期性分布的特点，随着单个ＥＣ的Ｒ（高／长）值的增加，切应力呈现上升的趋势；对相同的Ｒ值，迎来流面的切应力值大于背来流面的值．这一研究结果对于了解ＥＣ发生的物理、生理、、生化及基因重组等复杂反应从一个方面提供了有价值的知识．
The numerical simulation of the shear stress distribution on EC (endothelial cell) surface after steady flow at different inlet velocities in the flow cell was considered. The single EC was a quadratic curve, and the continuous distribution of multiple ECs was the cycle extension of the quadratic curve , With the increase of flow rate. EC has along the flow direction of elongation and cytoplasm in the flow direction of the forward. The results show that the shear stress shows the same periodic distribution with the shape of EC, and the shear stress tends to increase with the increase of R (height / length) of a single EC. For the same R value, Shear stress value is greater than the value of the back flow surface. The results of this study provide valuable information on understanding the complex reactions of physiology, physiology, biochemistry and gene recombination in EC from one aspect.
