Until his group's new report, scientists hadn't compared racemization and C-14 analyses on the same teeth, Buchholz says.
截至他的研究小组出台新报告之前，科学家们未曾对比过同一颗牙齿的外消旋化以及碳14分析结果，布赫兹说道。
By the way, if you're curious about why racemization is so much less accurate a clock than C-14 for dating a tooth's age, part of the explanation has to do with temperature.
顺便说一下，如果你好奇为什么在判断牙齿年龄方面、外消旋化会比碳14定义的时钟精度差之甚多，那么部分原因与温度相关。
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。
By analyzing how much racemization of its aspartic acid occurred, scientists can determine how old the tooth's owner was at death - generally accurate to about 5.5 years, plus or minus 4.2 years.
通过分析其天冬氨酸发生了多少外消旋化，科学家可以确定牙齿主人在多大岁数死亡——通常精确到5年半左右，正负差4.2年。
