Abstract

Results of an experimental study of blood properties are reported. To approach the boundary conditions of blood biophysics in a real flow, the viscoelastic measurements are carried out on surfaces coated with a 10-nm thick fibrous layer composed of extracellular matrix protein. For native whole blood, a plateau of the shear elastic modulus as a function of frequency is observed. The immediate consequence of the shear elasticity is that it is necessary to exceed the stress threshold so that blood can flow. This elastic threshold depends on the boundary conditions.

血液和血浆在脉管系统中的另一种观点

本文报道了一项血液特性实验研究的结果。为了接近真实流动中血液生物物理的边界条件，在涂有10 nm厚的细胞外基质蛋白纤维层的表面上进行粘弹性测量。对于天然全血，剪切弹性模量呈频率函数的平台。剪切弹性的直接后果是必须超过压力阈值才能使血液流动。这个弹性阈值取决于边界条件。
