An estimation of the age of an artifact, biological vestige, linguistic usage, etc.
确定事件或交易发生或生效的日期
The setting of a date on which an event or transaction is to take place or take effect.
Carbon dating is a common method for determining the age of ancient artifacts.
碳定年法是确定古代文物年龄的常用方法。
用法提示:此处“dating”是名词,指通过化学分析测定年代的科学技术。
Geologists use radiometric dating to estimate the age of rocks.
地质学家使用放射性测年法来估算岩石的年龄。
用法提示:“dating”作为名词,表示利用放射性同位素衰变测定地质年代的方法。
The dating of the fossil was done using uranium-lead techniques.
这块化石的定年是通过铀铅技术完成的。
用法提示:“dating”在此指对化石进行年代测定的过程,属于地质学领域的术语。
Radiometric dating of volcanic rocks provides accurate ages.
火山岩的放射性测年提供了准确的年龄。
carbon dating 是常用的测年方法之一。
Scientists use carbon dating to determine the age of organic materials.
科学家使用碳测年来确定有机物的年龄。
Modern dating techniques have greatly improved precision.
现代测年技术大大提高了精度。
特指碳-14方法,不能替代其他放射性定年方法
口语化,含义与radiocarbon dating相同,但更简略
通用术语,涵盖多种同位素,使用范围更广,可替代具体方法
强调给出精确数值,与相对定年(relative dating)相对,不能用于方法名称
与absolute dating类似,更侧重结果形式,正式书面用语

易错句子The fossil is dating to the Cretaceous period.
正确表达The fossil is dated to the Cretaceous period.
将'date'的现在分词与过去分词混淆。表示'确定年代'时,应使用过去分词'dated'来表示被动含义(被测定为某年代),而不是现在分词'dating'。
grammar · medium
易错句子The dating for this sample is accurate.
正确表达The dating of this sample is accurate.
介词误用。表示'某样品的年代测定'时,固定搭配使用介词'of',而非'for'。
放射性测年
Radiometric dating is widely used to determine the age of rocks and fossils.
放射性测年广泛用于确定岩石和化石的年龄。
碳定年
Carbon dating can estimate the age of organic materials up to 50,000 years old.
碳定年可估算长达5万年的有机材料年龄。
铀铅测年
Uranium-lead dating is one of the oldest and most refined radiometric dating methods.
铀铅测年是最古老且最精确的放射性测年方法之一。
钾氩测年
Potassium-argon dating is commonly used for dating volcanic rocks.
钾氩测年常用于火山岩的测年。
化石测年
Fossil dating often relies on associated radiometric dating of surrounding rock layers.
化石测年通常依赖于对周围岩层的放射性测年。
绝对测年
Absolute dating provides a numerical age, unlike relative dating which only orders events.
绝对测年提供具体数值年龄,不同于仅排列事件顺序的相对测年。
