Blood front

血界───blood boundary

In this paper, the deformation of two-dimensional red blood cell in linear shear flow is simulated using the immersed boundary method to observe the tank-treading motion.───本研究采用浸入边界法模拟二维红细胞在线性剪切流中的形变，观测细胞的坦克履带式运动。

The edge of all-directional M-mode echocardiography images is the combination of the cross points of the sample line and the boundary between the blood and the heart by the time.───全方向M型心动图的边界是采样线血液与腔室壁组织结构形成的分界线与采样线交点位置变化的按时间展开。

concluded that in same boundary conditions blood pumps based on stream-lined design have better blood compatibility and anti-thrombogenicity.───认为，在保持边界条件一致的情况下，流线型的叶轮血泵具有较好的血液相容性和抗血栓形成性能。
