另外，随着血管扩张程度的增加，管壁切应力还将进一步减小，而且管壁切应力梯度也将进一步增大。
Furthermore, the more the vessel expansion is, the less the wall shear stress will be and the more the gradient of wall shear stress will be.
文章以人体颈动脉余弦扩张为例进行分析，详细讨论了局部扩张对血管壁切应力及其梯度分布的影响。
As an example, the human carotid with local cosine form expansion was analyzed and the effects of local expansion on the distribution of wall shear stress and its gradient were discussed in detail.
