摘要
本文通过求解线性化的血液流动方程，导得局部扩张血管段内压强和切应力的分析表达式，并通过局部扩张随时间发展的规律，讨论了血管局部扩张段内压强和切应力随时间发展的情况。结果表明在局部扩张血管段内，压强与均匀血管段的结果相比略有提高，而切应力则明显下降，对血管组织起一定的影响。
In this study, the analytical expressions of pressure and wall shear stress in local vessel expansion region were deduced through solving the linear blood now equations. with the assumption of the development process mode of the local vessel expansion with time, the progresses of the pressure and wall shear stress in local vessel region were discussed. Results show that in the local vessel expansion section, the pressure is slightly larger than that in the uniform vascular section, and that the shear stress decreases significantly, which will have some effects on vessel tissues.
