摘　　要：本文提出了一种从重迭的穆斯堡尔谱中求解两套超精细场分布的方法，从而改进了Hesse提出的方法，解谱结果表明，对于Ca2Al0.26Fe1.74O5固溶体的穆斯堡尔谱，采用本文推荐的方法进行拟合，x^2显著下降，而且，超精细场的分布反映了结构中两种亚点阵的存在。A procedure, which has improved the Hesse method, for the evaluation of two hyperfine fields, distributions from overlapped Mossbauer spectra is proposed. In fitting the Mossbauer spectrum of the solid solution Ca_2Al_(0.26)Fe_(1.74)O_5,x^2 decreases remarkably by using the procedure proposed. Furthermore, the distributions of two hyperfine fields reflect two sublattices in the crystal structure.
