一、引言在周围血管系统里血液流动的详细情况对于许多临床病因是重要的。往往炎症和疾病的第一个迹象是周围血流有大的变化。血液在性质方面的变化,如它的粘性、红细胞的形状或硬度、管壁流变学性质的变化(动脉粥样硬化等)都有可能伴随毛细血管血流流谱的改变而有较大的变化。Dintenfass(1976)血流对于局部刺激的反应也是感兴趣的,Atherton同Born(1973)。研究在小血管中血流的最明显方法是直接地观察它们。事实上,显微电影摄影术和简单地显微镜的观察在目前已被用来研究这样的流动。然而,用这些方法数据的积累是
I. INTRODUCTION The details of blood flow in the peripheral vascular system are important for many clinical causes. The first signs of inflammation and disease are often large changes in the peripheral blood flow. Changes in the nature of the blood, such as its viscosity, red blood cell shape or hardness, changes in wall rheology (atherosclerosis, etc.) are likely to be accompanied by changes in capillary blood flow spectrum and have a larger Variety. Dintenfass (1976) Blood flow is also of interest for local stimulation, Atherton and Born (1973). The most obvious way to study blood flow in small blood vessels is to look directly at them. In fact, microscopic cinematography and simple microscopic observations have so far been used to study such flows. However, the accumulation of data using these methods is
