尸僵

尸僵通常在死后2至4小时内出现。

Rigor mortis usually sets in between two and four hours after death .

早期尸僵和迅速自溶解提醒必须迅速进行剖检。

Early rigor mortis and rapid autolysis indicate the need for prompt necropsy examinations .

又分别在宰后16和13小时结束尸僵过程，pH到达终点。

After slaughter 16 hours and 13 hours . And the pH - value was stable .

目的观察尸僵再形成中肌节长度的变化。

Objective To observe changes of the length of sarcomere of rat when restiffening .

这是更好地移动，让事情，而不是让组织尸僵做一套英寸。

It 's better to move and get things done than to let organizational rigor mortis set in .

结果死后未破坏的尸僵肌节的长度明显小于尸僵再形成时的长度。

Results The length of sarcomere of rigor mortis without destory is obviously shorter than that of restiffening .

尸僵会出现在死后3到6小时内，并将持续24到48小时。

The stiffness referred to as rigor mortis sets in three to six hours after death , and lasts for between 24 and 48 hours .

尸僵形成的基本生化过程与肌肉收缩是一致的，不同的是前者发生在死后，后者发生在生前。

The basic biochemical process for the formation of rigor mortis is the same as that of muscle contraction except that the former happens postmortem and the latter antemortem .

结论肌节长度与尸僵强度呈负相关，说明肌节长度可确定尸僵强度，从而为推断死亡时间提供依据。

Conclusion The length of sarcomere is negatively correlative to the intensity of rigor mortis . Measuring the length of sarcomere can determine the intensity of rigor mortis and provide evidence for estimation of time since death .
