尸体腐败程度与死亡经过时间的实验研究

为了找出推测死亡经过时间的客观依据,应用健康的苏白猪为实验模型,进行尸体腐败程度与死亡经过时间研究,将模型分别放置在室内、室外及地下三个环境中,让尸体在自然的环境中发生腐败,详细记录尸体腐败所表现的现象,特别是腐败气体所产生的张力。实验发现,尸体腐败至软组织与骨骼全部分离、以及腐败残留物质的完全消失,与温度、湿度、降雨量、尸体与地面倾斜度、昆虫的寄生等有明显的关系。所得数据,为死亡经过时间的推测,积累了重要的参考依据。

An experimental study of corpse decay degree and timing of death

In this study, we put dead pigs indoors, outdoors and underground respectively, and kept a detailed record of the natural decay process, especially the tension of the pig's abdomen produced by corruptive gas. The result showed that the decay speed was closely related to temperature, humidity, rainfall, position of corPses on the ground, insect parasitism. The obtained data could pro-vide an important referential basis for inferring time after death.
