本研究利用加速器质谱放射性碳（AMS 14 C）测量日本近代中期至早期的树木年轮，以研究校准曲线的精细结构。日本树木的年轮年龄由树木年代学或δ 18 O年代学确定。15世纪至17世纪世纪中期的~（14）C年龄在测量误差范围内遵循IntCal ~（13）校准曲线。不同树种在17世纪后半期至18世纪初的波动模式不同。在19世纪，不同样品的14 C年龄模式看似相似，但并不完全匹配。
This study carried out accelerator mass spectrometry radiocarbon (AMS 14C) measurement of Japanese tree rings dating from the middle to early modern eras to investigate calibration curve fine structure. Tree-ring ages were determined by dendrochronology or δ18O chronology for Japanese trees. 14C ages from the 15th century to the middle of the 17th century followed the IntCal13 calibration curve within measurement error. Different patterns of fluctuations during the latter half of the 17th century to the early the 18th century were observed in different tree samples. In the 19th century, patterns of 14C ages of different samples appeared similar but did not exactly match each other.
