摘要

这项研究的目的是确定流动模式的特征取决于血迹形成的表面的倾斜角。供者血大滴80µL。实验得到了玻璃上的直线条形流型。表面倾角分别为30°、45°、60°、75°。随着倾角的增大，流型长度从24.5±0.07 cm增加到48.3±0.02 cm，宽度从0.8±0.04 cm减小到0.5±0.03 cm。流型结构的要素被指定为“头部”、“主体”和末端部分。建议区分两种类型的血流模式：第一种是血液从伤口流出时形成的，第二种是水滴或有限的血块落在垂直或倾斜表面时形成的。

[Flow pattern characteristics depending on angle of inclination of bloodstained surface].

The aim of this study is to determine the flow pattern characteristics depending on the angle of inclination of the surface on which bloodstains are formed. A large drip of donor human blood 80 µL was used. Experimental rectilinear strip-shaped flow patterns on the glass were obtained. The surface had a inclination of 30°, 45°, 60°, 75°. With increasing inclination angle, the length of the flow patterns increases from 24.5±0.07 to 48.3±0.02 cm, while the width decreases from 0.8±0.04 to 0.5±0.03 cm. The elements of the flow pattern structure are designated «head», «body» and end part. It is proposed to distinguish two types of flow pattern: the first one is formed when blood flows out of wound, the second one is formed when a drip or a limited blood mass falls on vertical or inclined surface.
