The floating dendrochronological sequence of pine wood from Józefowo, N. Poland was expected to cover the ∼660 BC radiocarbon (14C) excursion. The sequence was radiocarbon dated using the OxCal wiggle matching procedure and the IntCal20 calibration curve. 14C concentrations were measured in one-year α-cellulose samples from around 660 BC. The published data on the ∼660 BC 14C excursion from Grabie, Poland were used to absolute date the Józefowo chronology with 1-year accuracy. The results confirm the occurrence of a rapid increase in Δ14C in 664/663 BC and its potential to be used as a fixing point for floating dendrochronological sequences.

利用公元前 7 世纪 14 摄氏度的快速大气变化来精确确定约泽福沃（波兰北部）松木漂浮的年代

来自波兰北部约泽福沃的松木漂浮的树木年代序列预计涵盖约公元前 660 年的放射性碳（14C) 游览。使用 OxCal 摆动匹配程序和 IntCal20 校准曲线对序列进行放射性碳测年。14在公元前 660 年左右的一年α-纤维素样品中测量了 C 浓度。已发表的约公元前 660 年的数据14来自波兰格拉比的 C 旅行被用来对 Józefowo 年表进行绝对年代测定，精度为 1 年。结果证实了 Δ 的快速增加14公元前 664/663 年的 C 及其用作浮动树木年代序列固定点的潜力。
