摘要
目的通过动物实验,探寻嗜尸蝇类蛆的生长长度与尸体死亡时间之间的关系,从而为判断尸体死亡时间提供参考依据。方法将实验用犬击毙后观察尸蝇来到犬尸上的时间、产卵时间、卵期、蛆增长到规定长度所需时间。结果证实蛆虫长度与尸体死亡时间存在正相关性,并进而推算出相关系数θ,从而推导出了一个通过蛆虫长度计算尸体死亡时间的公式。结论通过实际案例的验证,通过该公式可以计算出尸体的大致死亡时间。
Objective Through animal experiments, to study the relationship between the growth time of the maggot fly and the time of death, so as to provide reference to estimate the time of death, Methods After the dogs had been shot, to observe the time of maggot fly coming to the dog remains, the time of ovipositing, the time of being eggs, and the time of maggots growing to the definite length. Results There is the direct connection between the length of maggot and the time of death, with relevance ratio θ, a formulation about calculating the time of by the length of maggot was deduced. Conclusion Through testifying actual case, the time of death can be estimated by using the formulation.
