Lanthanide Complexes with Acetylacetone and 5-(4-Nitrophenyl)-10,15,20-Triphcnylporphyrin Ligands

Five lanthanide porphyrin complexes with 5- (4-nitrophenyl) -10, 15, 20-triphenylporphyrin and acetylacetonate ligands were synthesized and characterized by elemental analysis, IRspectra, Uv-visible spectra, IH NMR. The structures of the complexes were proposed.

赋值环上的Hermite环猜想

本文主要研究赋值环上的Hermite环猜想.根据赋值环V上一元多项式环V[x]的性质,研究并得到V[x]上幺模行向量(a_(1)(x),a_(2)(x),…,a_(n)(x))的一系列关于等价的性质,进而证明了赋值环上的Hermite环猜想成立,即对任意的赋值环V,V[x]都是Hermite环.
