摘      要:Two national stalagmite standard (GBW04412, GBW04413) and one international coral standard (RKM4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of ( 234 U/ 238 U) act , ( 230 Th/ 234 U) act and age are all consistent in error range with the standard values obtained by using α spectrometry.
