On the basis of the analysis of high voltage driving waveforms and the consideration of the driving circuit design of scan electrode, the design method of the high voltage driving circuit of scan eletrode, and the energy recovery circuit are studied.

In this paper,we introduce the advantages of ALIS driving method,and the design of the driving circuit of scan electrode;Using MAX+plusⅡsoftware,the driving waveform of scan electrode was realized through combining Text editor with Graphic editor.

In this work,the scanning microelectrode technique and potentiodynamic polarization were used to study the localized corrosion behavior of the reinforcing steel in simulated concrete pore solution with different pH values and chloride ion concentrations.

Determination of homocysteine by single-sweep oscillopolarography;

A sansitive method for the determination of CTD by single-sweep oscillopolarography was developed.

This paper not only concerned about the analysis on the content of Pb,Cd,Zn,Cu,Mn and Cr by single sweep polarography,but also the comparison between the researched result and the national security quality standard of agricultural products.

Objective: To establish a simple rapid method for determining Kjeldahl nitrogen content by 1st order differential coefficient single sweep polarography.

01mol/ L by single sweep polarography has been established.
