They had suppressed the cathodic process of carbon steel electrode. Their inhibition performance was also related with their molecule stereo conformation and electron configuration. Four of bis-(1, 1'-benzotriazoly)-α,β-diamide compounds linked via-CO 〓CO-chain were synthesized and certified by IR and 〓H-NMR. The minimum energy conformations of these compounds were obtained by MM2 forcefield program. The two benzotriazole moiety in BBT1 was more planar than in other compounds. This was beneficial in increasing the inhibition effects of BBT1. In 0.5M H〓SO〓 solution, BBT1 suppressed anodic corrosion reaction. In 3%NaCl solution, BBT1 suppressed both cathodic and anodic corrosion reactions. 1- [ (1'-imidazolly)-methyl] benzotriazole was synthesized by Mannich reaction.

合成了四个通过-CO〓CO-连接的双（1，1'-苯并三唑）-α，ω-二酰胺化合物，采用MM2分子力学程序优化了它们的分子结构，双（1，1'-苯并三唑）-α，ω-二酰胺化合物的缓蚀作用与其分子内两个苯并三唑单元的空间取向有关系，良好的平面性有利于苯并三唑二聚体的吸附和缓蚀作用，苯并三唑二聚体BBT1分子内两个苯并三唑单元近似平行，所以显示出较好的缓蚀效果。0.5M硫酸中BBT1主要抑制铜的阳极溶解的电化学反应；3％NaCl溶液中，BBT1对铜的阳极溶解和氧的阴极还原过程均有抑制作用，相比较而言对阴极过程的抑制作用更大一些。

The results show that non-sequential double ionization rate and the double ionization events that sum of two-electron momentum equals zero increase with the molecular internuclear distance increasing when the molecular internuclear distance is within 1.0a.u.

The results showed that the MS2 fragmentation pathways of DASSSB were affected by the character and position of substitutes on salicylidene phenyl. The C=N cleaving to form fragmentation ion [M+H-283](superscript +) was dominant for DASSSB compounds with electron-donating group on the C4 of the salicylidene phenyl; while fragmentation ion [M+H-254] (superscript +) forming by C-C cleavage of the β-position of C=N was dominant for DASSSB compounds with electron-withdrawing group on the C5 of the salicylidene phenyl.

结果显示，这些化合物的ESI-MS/MS裂解方式与它们分子中水杨醛苯环上取代基的性质和位置有关：当水杨醛苯环上4位连接供电子取代基时，分子以CN双键断裂为主，生成[M+H-283]碎片离子；当水杨醛苯环上5位连接吸电子取代基时，分子以CN双键β位的C-C键发生断裂为主，生成[M+H-254]碎片离子。

A metal-organic complex thin film, constructed by Cu and a new organic material 3,9-dianthracene-10-(dicyanomethylene-9--2,4,8,10-tetrathiaspiro [5,5] undecane was reported. The device with a sandwich structure can be transferred from high to low-impedance under 6V with delay and switching times of less than 1000 and 30 ns, respectively.

Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.

通过测定直接大红染料脱色过程中的溶液pH、TOC、紫外可见光谱图和高效液相色谱图可知，在脱色处理时间(6h)范围内，染料溶液的COD值增大， pH值持续下降，TOC值逐渐降低，结合紫外可见光谱图和高效液相色谱图，说明染料分子虽然已经遭到破坏，染料分子内强生色基团偶氮双键确实遭到攻击，大的共轭体系被破坏，染料分子被脱色，却没有完全被彻底矿化成二氧化碳等无机物，出现了芳环和萘环结构的累积现象，可见完全破坏芳环比破坏偶氮双键发色团更困难。
