However, when the researchers applied both techniques to teeth, they realized that the racemization offered an additional useful detail, a good gauge of an individual's age at death.

然而，当研究人员将两项技术一并运用于牙齿上，他们意识到外消旋化提供了一个额外的有用细节，能成为个体死亡年龄的良好衡量标准。

Using strain gauge at roots of the teeth, the contact ratio of gears is measured under different loads.

通过在齿根贴电阻应变计，测量了在不同载荷下螺旋锥齿轮的重合度。
