The method of the tangent simple systems is applied to the study of the viscoelastic behaviour of human blood in unstationary flow for rectangular steps and triangular ramps of shear rate. The tangent systems we utilize, Maxwell liquids, enable us to determine, at every point of the rheograms, apparent instantaneous values of retardation or relaxation time, viscosity coefficient and elasticity modulus of the studied blood samples, and to plot the curves of variation of these parameters as a function of flow duration. A qualitative interpretation of the results is proposed from data on the aggregation-disaggregation kinetics of red blood cells. Examples are given for samples of normal and pathological bloods.
切线简单系统的方法被应用于研究人体血液在非定常流动中，针对剪切速率的矩形阶跃和三角形斜坡的粘弹性行为。我们所使用的切线系统，即麦克斯韦流体，使我们能够在流变图的每个点上确定所研究血液样本的延迟或松弛时间、粘度系数和弹性模量的表观瞬时值，并绘制这些参数随流动持续时间变化的曲线。根据红细胞聚集 - 解聚动力学的数据，对结果进行了定性解释。给出了正常血液和病理血液样本的示例。
