Each of the laboratory intercomparisons (from ICS onwards) has included wood samples, many of them dendrochronologically dated. In the early years, as a result of the majority of laboratories being radiometric, these samples were typically blocks of 20–40 rings, but more recently (SIRI), they have been single ring samples. The sample ages have spanned background through to modern. In some intercomparisons, we have examined different wood pretreatment effects, in others the focus has been on background samples. In this paper, we illustrate what we have learned from these extensive intercomparisons involving wood samples and how the results contribute to the global IntCal effort.

从 ICS、TIRI、FIRI、VIRI 和 SIRI 中的木材样本中学习

每次实验室比对（从 ICS 开始）都包括木材样品，其中许多是按树木年代顺序排列的。早些年，由于大多数实验室都是辐射测量的，这些样品通常是 20-40 环的块，但最近 (SIRI)，它们一直是单环样品。样本时代跨越了背景到现代。在一些比较中，我们检查了不同的木材预处理效果，在其他比较中，重点是背景样本。在本文中，我们说明了我们从这些涉及木材样品的广泛比对中学到了什么，以及结果如何为全球 IntCal 工作做出贡献。
