| Abstract: | Recently ESR Dating Method develops quickly,supplying a gap of Unbalanced U System Dating Method and ~(14)C Dating Method.This paper gives a brief presentation of the rationale and characteristic of ESR Dating Method.Emphatically it introduces the application and questions in the loess.The questions contain the choice of quartz(SiO_2),the choice of ESR signal in the young loess, the mensuration of initial dosage,the contribution of cosmic radial to the samples, the influence of quartz(SiO_2) recrystallization to the annual dosage,the emendation of radioelement disintegration disciplinarian,the emendation of water quantity, the transfer of radioelements round the samples and so on. |
