在用Blichfeldt定理证明Minkowski定理的过程中,对于格点对称性及直线斜率的存在性没有进行讨论,对其中遗漏的2种情形进行了补充讨论,从而改进了原有的证明.
The original proof of Minkowski' s theorem by Blichfeldt' s theorem doesn' t discuss the symmetry of lattice points and existence of the line slope. A remedy to this gap is given and therefore the original proof is improved .
