Down-core variations of the SIRM for CON01-603-2.

The concentration in ferromagnetic particles is much lower in the interglacial sediments than in glacial sediments. Therefore, the NRM needs to be normalised by a...间冰期沉积物中的铁磁性颗粒浓度远低于冰期沉积物。因此，需通过……对自然剩余磁化强度（Natural Remanent Magnetization，NRM）进行归一化处理。
