摘      要：We review some recent progress in our understanding of the lowest-lying spin-1/2 and spin-3/2 baryon magnetic moments （MMs） in terms of Chiral Perturbation Theory （ChPT）.In particular,we show that at next-to-leading-order ChPT can describe the MMs of the octet baryons quite *** also make predictions for the decuplet MMs at the same chiral *** them,the MMs of the Δ＋＋ and Δ ＋ are found to agree well with data within the experimental uncertainties.
