Novel transition metal complexes of bis (diarylsubstitutedthiophosphoryl) imines ligand derived from O,O-di (p-methoxylphenyl) thiophosphoryl chloride and O,O-di-(p-methoxylphenyl) thiophosphoryl amine with Cu(Ⅱ), Co(Ⅱ), Ni(Ⅱ), Fe(Ⅱ)and Mn(Ⅱ) were synthesized. The formation mechanism of complexes and their stereochemistry structures were investigated according to elemental analysis, infrared spectra and 31P-unclear magnetic resonance spectra. The extractions of the ligand for different divalent metal ions, such as Zn(Ⅱ), Cd(Ⅱ), Cu(Ⅱ), Ni(Ⅱ), Fe(Ⅱ), Sn(Ⅱ), Mn(Ⅱ), Pd(Ⅱ), Hg(Ⅱ) and Fe(Ⅲ), were investigated in sulphate solution, respectively. The results show the metal atom is coordinated by 4 sulfur atoms in a square-planar fashion, and the titled compound has not only powerful ability to coordinate with cadmium from aqueous solution with a high extractive rate about 61.20% and a relatively weak complexation for other divalent metals with the extractive rate from 2.46% to 36.66%, but also a good selectivity to Fe(Ⅲ).

为了提高虹膜定位的精度和可靠性,提出了两种改进的Snake模型来分别定位虹膜的内外边缘。使用未滤波的虹膜梯度图像,同时,引入蛇点法线方向的归一化向量,使这些向量的方向都指向虹膜的内边缘,在这两个因素作用下来完成Snake模型对虹膜内边缘的定位。定位虹膜的外边缘时,在传统Snake模型的基础上,引入指向轮廓型心的归一化向量,即先求取Snake的型心,然后求取型心至每个蛇点的归一化向量,使它们都指向S
