摘要： 乙醇和正丁醇大量存在于溺水尸体中。其浓度与尸体在水中的浸泡时间有一定的相关关系。温度能影响上述的相关关系。在自然平均温度１５—１８℃的条件下，运用气相色谱法测定其溺死后不同浸泡时间在血、肺、肝中存在的乙醇和正丁醇含量。其合并后回归方程式依次为ｙ１＝１１５．７２＋１８．２４ｘ；ｙ２＝－４１９．７１＋６４．７０ｘ；Ｙ３＝－３０３．０７＋５４．８７ｘ。研究中发现，溺死后７—１３天内，运用本方法来判断溺死时间的准确性较好。

Abstract: Autopsy samples of blood, lung and liver taken from the immersed guinea- pags in nature temperature of 15 - 18degree centigrade, were analyzed by headspace gas chromatography. As a result, the linear regressive equations between combined concentration of alcohol and n - butanol in blood, iung and liver and the length of submerging time were respectively as follows: Y1=- 115. 72 + 18. 24X,Y2= - 419. 71+64. 76X, Y3= - 303. 07+54. 87X.The method was relatively accurate within the range of 7 - 13 days after drowned death.
