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。

What this paper finished mainly work as follows: Five-phase hybrid step motor driver system with fixed-chopping frequency and constant total current driving is fully described. Mathematical model of the system, included the current control circuit, power driving circuit and five-phase hybrid stepping motor is established. The steady modeling of the system is established and studied. Based on the steady modeling of the system, dynamic modeling of the system is studied and single step response characteristic is constructed with MATLAB/Simulink. The simulation results, which is certified by the theory analysis, coincide with the theory analysis.
