死亡时间的推测是法医病理学研究的重点和难点,对晚期死亡时间的推断误差较大。皮肤是机体死后分解破坏发生较迟的部分。不同环境条件下死后不同时间大鼠皮肤大体、组织学的改变,为推测较长的死后间隔时间建立实验动物依据。利用皮肤大体、组织学改变可望较系统和准确地推测晚期死亡时间。 The speculation of death time is the key and difficult point of forensic pathology research, and the estimation error of late death time is larger. The skin is the body part of the decomposition after the death of the later part. Under different environmental conditions at different times after the death of rats skin general, histological changes, in order to speculate longer interval after the death of experimental animal basis. The use of the skin, the histological changes expected more systematic and accurate prediction of late death.
