对违反银行保密义务行为之探析

商业银行法第二十九条第一款、第二款,第三十条与第五十三条这三条规定可说是我国有关银行保密方面规定得最直接的规定,但规定得很笼统,对违反银行保密义务的行为,是侵权还是违约,要负何种民事责任,应该怎样承担的问题,商业银行法并没有作出具体规定,仅有在第七十三条第四款对银行应该承担民事责任的笼统规定,可以说是立法的一大缺陷,因此本文将对此进行论述

Synthesis and Solution Properties of Polyacrylamide Containing Sulfobetaine Groups

用丙烯酰胺(AM)、n,n-二甲基丙烯酰胺(dMAM)、[3-(甲基乙烯酰胺)丙基]二甲基-(3-磺酸)铵(dMMPPS)和[2-(甲基丙烯酰基氧基)乙基]二甲基-(3-磺酸丙基)氢氧化铵(dMAPS)单体通过氧化还原引发剂引发自由基聚合合成AM-dMMPPS、AM-dMAM-dMMPPS、AM-dMAPS和AM-dMAM-dMAPS 4种两性离子共聚物,并对两性离子聚合物进行表征和性能评价.研究结果表明,实验合成的4种共聚物AM-dMMPPS、AM-dMAMdMMPPS、AM-dMAPS和AM-dMAM-dMAPS都有增黏、抗盐、耐温的效果.在相同的反应条件下,在合成的共聚物中,AM-dMMPPS增黏、抗盐、耐温的效果最佳,其比浓黏度达36.8,dl/g.Four kinds of zwitterionic copolymers(AM-DMMPPS,AM-DMAM-DMMPPS,AM-DMAPS and AMDMAM-DMAPS) were synthesized by free radical copolymerization of acrylamide(AM), N, Ndimethylacrylamide(DMAM),[3-(methacryloylamino)propyl]dimethyl(3-sulfopropyl) ammonium hydroxide inner salt(DMMPPS)and [2-(Methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide(DMAPS).The copolymers were characterized and their solution properties were evaluated.The results show that the existence of the copolymers enhances the viscosity of the aqueous solution and the copolymers exhibit favorable salt resistant and thermal stable properties.At the same condition of copolymerization,in all synthesized copolymers,the AMDMMPPS copolymer has the most excellent properties of aqueous thickening and heat and salt resistant effect,and the highest reduced viscosity of the copolymer solution is 36.8,dL/g.国家自然科学基金资助项目(20876108

NMR Studies on Interactions between Diperoxovanadate and N-Substituted Picolinamide

为了探讨有机配体上取代基团对反应平衡的影响,在模拟生理条件下(0.15mol/LNaCl溶液),应用多核(1H,13C和51V)多维(COSY和DOSY)NMR以及变温技术等谱学方法研究双过氧钒配合物[OV(O2)2(D2O)]-/[OV(O2)2(HOD)]-与N-取代皮考啉酰胺的相互作用.它们反应性从强到弱的顺序为:N-甲基-皮考啉酰胺≈N-(2-羟乙基)-皮考啉酰胺>N-乙基-皮考啉酰胺>N-丙基-皮考啉酰胺,这说明了皮考啉酰胺N上取代基的电子效应影响反应.竞争配位导致一系列新的7配位的过氧钒物种生成,而利用上述谱学方法则有助于揭示此类相互作用体系的反应过程和配位机制.To understand the substituting effects of organic ligands on the reaction equilibrium, the interac- tions between diperoxovanadate complex [OV(O2)2(D2O)]-/[OV(O2)2(HOD)]- and a series of N-substituted picolinamide ligands in solution were explored using multinuclear (1H, 13C, and 51V) magnetic resonance, COSY, DOSY, and variable temperature NMR in 0.15 mol/L NaCl ionic medium for mimicking the physio- logical conditions. The order of reactive capability of the picolinamide-like ligands with [OV(O2)2(D2O)]-/ [OV(O2)2(HOD)]? is as follows: N-methylpicolinamide ≈ N-(2-hydroxyethyl)picolinamide > N-ethyl- picolinamide>N-propylpicolinamide. The substituting group influences the reactivity by an electron effect. Competitive coordination interactions result in a series of new seven-coordinated peroxovanadate species [OV(O2)2L]-(L=N-substituted picolinamide).973子课题(No.2003CB716005);; 国家自然科学基金(No.20772027);; 湖南省自然科学基金(No.06JJ30004);; 中国博士后科学基金(No.20070410805);; 卫生部(福建省)卫生教育联合攻关计划(No.3502Z20051027);; 厦门市重大疾病攻关研究基金(No.Wkj2005-2-019);; 固体表面物理化学国家重点实验室开放基金;; 湖南科技大学博士基金(No.E-55107)资助项目

NMR studies on interactions between diperoxovanadate and N-substituted picolinamide

To understand the substituting effects of organic ligands on the reaction equilibrium, the interactions between diperoxovanadate complex [OV(O-2)(2)(D2O)(-)/[OV(O-2)(2)(HOD)](-) and a series of N-substituted picolinamide ligands in solution were explored using multinuclear (H-1, C-13, and V-51) magnetic resonance, COSY, DOSY, and variable temperature NMR in 0.15 mol/L NaCl ionic medium for mimicking the physiological conditions. The order of reactive capability of the picolinamide-like ligands with [OV(O-2)(2)(D2O)](-)/[OV(O-2)(2)(HOD)](-) is as follows: N-methylpicolinamide approximate to N-(2-hydroxyethyl)picolinamide > N-ethylpicolinamide>N-propylpicolinamide. The substituting group influences the reactivity by an electron effect. Competitive coordination interactions result in a series of new seven-coordinated peroxovanadate species [OV(O-2)(2)L](-) (L=N-substituted picolinamide)

SEM analysis of Particles and its effects in arc ion plating

用扫描电镜对比分析了电弧离子镀增加直线磁场过滤对沉积TiN和TiAlN薄膜中颗粒的密度和尺寸的影响，，结果表明，TIN薄膜中颗粒的最大直径，从14μm减小到3μm，颗粒密度从lO~9／cm~2。降低到10~5／cm~2.TilN薄膜由于靶材中含有低熔点金属Al，因而发射出更大的颗粒，有的颗粒集团达到20μm，磁场过滤后颗粒尺寸减小，颗粒密度降低到10~6／cm~2。分析了脉冲叠加直流偏压对TiCrZrN复合薄膜相组成的影响。颗粒可使电弧离子镀rriN／crN多层膜的结合力降低，并使针孔产生遗传。使用直线型磁场过滤及脉冲叠加直流偏压不仅使颗粒密度和尺寸显著降低和减小，而且多层化对小颗粒产生了包覆作用
