摘要： 目的 寻找一种精确推定 PMI的方法。方法 应用电感耦合等离子体质谱（ ICP－ MS），检测了家兔死后 96小时内眼玻璃体液锌、镍元素含量，探讨其与 PMI的相关性。 结果 家兔死后 24h内眼玻璃体液锌、镍元素含量与 PMI显著相关，可作为推定早期 PMI的参考指标，其二项式回归方程分别为 y=0.140 4x2－ 1.335 1x＋ 3.829 8（ R2=0.920 2）、 y=0.004 3x2－ 0.059 6x＋ 0.266 5（ R2=0.910 3）。 结论 家兔眼玻璃体液中 Zn、 Ni元素含量变化是推定早期 PMI的参考指标之一。

Abstract: Objective To seek a exact method of estimating postmortem interval (PMI). Methods This study detected the concentration of zincum(Zn) and nickel(Ni) in vitreous humor of rabbit at hour 96 after death and explored the relationship between their concentration and PMI using a method ICP－ MS. Results The concentration of Zn and Ni in vitreous humor of rabbit at hour 24 after death were related to PMI significantly; The formulae of the relationship between PMI and Zn concentrations is y=0.140 4x2－ 1.335 1x＋ 3.829 8（ within 24h; R2=0.920 2） .The formula of the relationship between PMI and Ni concentrations is y=0.004 3x2－ 0.059 6x＋ 0.266 5（ within 24h; R2=0.910 3）。 Conclusion The concetration of Zn and Ni in vitreous humor of rabbit may be a reference indicator to estinmate early PMI.
