Abstract This paper revisits the usage of spatially averaged haemodynamic models such as non-stationary 1D/0D in space and stationary 0D in space models. Conditions of equivalence between different 1D model formulations are considered. The impact of circular and elliptic shapes of the tube cross-section on the friction term and the tube law is analyzed. Finally, the relationship between 0D lumped and 1D models is revealed.

心血管系统不同部位的空间平均血流动力学模型

摘要 本文回顾了空间平均血液动力学模型的使用，例如空间中的非平稳 1D/0D 和空间模型中的平稳 0D。考虑了不同一维模型公式之间的等效条件。分析了圆形和椭圆形管截面形状对摩擦项和管定律的影响。最后，揭示了 0D 集总模型和 1D 模型之间的关系。
