对陕西黄土的多矿物细粒样品进行了红外释光（IRSL）预热条件的确定。通过对在不同的预热时间及不同的预热温度下，（N＋β）／N的比值以及ED值的稳定性的对比认为，黄土细粒样品的IRSL测年5min或10min、200－250℃，或160℃6h是可选的预热条件。
The determination of IRSL preheating conditions for the multi-mineral fine-grained samples of loess in Shaanxi Province was carried out. By comparing the ratio of (N + β) / N and the stability of ED at different preheating time and different preheating temperature, it is considered that the IRSL dating of loess fine particles is 5min or 10min, 200-250 ℃, Or 160 ℃ 6h is optional preheat conditions.
