人们早已发现,在微血管分岔处流入侧支微血管的红细胞压积往往低于主管中的值,这一现象对于微循环生理学研究具有重要意义。在主管上游,那些能流入侧支管的流体与将要沿主管向下游流动的流体之间有一个分界面。本文工作的目的就是用在主管上游注入染料并观测它们在分岔处流向何方的方法,来确定上述分界面 It has long been discovered that the hematocrit inflow into collateral vessels at the microvessel bifurcation is often lower than that in the superficial vessels, a phenomenon that is important for microcirculation physiology. Upstream of the supervisor, there is an interface between the fluid that can flow into the side branch and the fluid that will flow downstream along the main line. The purpose of this work is to identify the above interface by injecting dyes upstream and observing where they flow at the bifurcation
