Abstract: A practical regression method of saturation exponential in pre-dosc technique is proposed. The method is mainly applied for porcelain dating. To test the method, some simulated paleodoses of the imitations of ancient porcelain were used, The measured results are in good agreement with the simulated values of the paleodoses, and the average ratios of the two values by using the two ways are 1.05 and 0.99 with standard deviations (±1σ) of 19% and 15% respectively. Such errors can be accepted in porcelain dating.
