Abstract：On the basis of analyzing the cuboid ΔT field and its theoretical expression of gradient field presented by Mr.Guo Zhi-hong et al.that there exist some analytic singular points in hp-half source-free space where the field value is unable to be computed,the paper first introduced the Eular equation into theoretical expression of cuboid magnetic field and anew deduced the expression,resulting in the theoretical expression of the cuboid ΔT field and its gradient field without analytic singular points in hp-half source-free space,which has not only the advantages of simple and uniform form,but also important theoretical and practical meaning.The correlation of model forward computation showed the newly deduced theoretical expression of the cuboid ΔT field and its gradient field without analytic singular points is correct.
