    死亡时间(续)

          死亡时间还可以用眼球化学法来预测:人死后红细胞会破裂,其中K元素会慢慢进入眼房水里,从而可预测死亡时间。
          鞣酸,酸性物质充当了尸体的防腐剂。
          对脂肪类的食物,胃的排空慢,同时新陈代谢的变化也影响胃的排空,同一人在不同的时间有不同的消化速度,这取决于健康和情绪状态。eg:神经性严重头痛后,食物在胃内可以呆几天,而且看起来和刚吞进去一样。(一餐在胃内停留时间约两小时左右。)
          法庭考古学的基础,靠尸体掩埋后的周围土壤层的特殊结构来鉴定的。在此不做展开,有兴趣可以看《科学探案》P166  o(^_^)o
          激烈的运动往往会阻碍消化。突然的精神创伤会使消化完全停止。
