摘要

分别从不同地点采集了不同沉积类型和粒径大小的２个现代样品。经红外释光（ＩＲＳＬ）信号检测表明，粒径为细砂以下样品的天然ＩＲＳＬ信号强度极小，已被相当彻底地光晒退；而粗砂样品则保留着相当水平的天然ＩＲＳＬ信号。这对于ＩＲＳＬ测年和物理模型的检验具有重要意义。

Abstract

Twenty seven samples were collected with different sediment features and grain sizes. Their IRSL intensities were measured and the equivalent dose D E extrapolated. The experiments show that all samples with fine grain size usually present a very low natural IRSL intensity due to a complete bleaching while the coarse ones have a considerable residual IRSL level.
